I-Amazon idume ngezakhamizi zayo nge-BIG SIZE, futhi isivakashi sethu namuhla sesibe ngumuntu wabo bonke ubugqi baseNingizimu Melika. Hlangana nenhlanzi enkulu enamanzi amasha emhlabeni, inkosi yamachibi - i-arapaim enkulu.

Njengenkosi yeqiniso, i-arapaima igwema isiphithiphithi nokuxinana, ikhetha amachibi athokomele ambozwe imifino yempilo enhle. Isiqhwaga asithandi imifula enesivunguvungu, ithanda ukuhlala embusweni wayo omncane kodwa opholile odakeni nase-algae. Ngakho-ke, e-Amazon ngokwayo azikho eziningi zalezi zinhlanzi. Kepha kumaxhaphozi aluhlaza eduzane nomfula omkhulu ongaphezu kwama-arapime kungaba kuningi.

I-Arapaima iphila impilo ezolile ekuphumuleni okuphelele. Lapho esefinyelele osayizi abanjalo, umuntu okhulileyo nakanjani ngeke awele emazinyweni omuntu. Ngaphandle komuntu, kepha ngaphezulu kulokho ngokuhamba kwesikhathi. Ngendlela, isilwane senziwe kabusha futhi sasendulo. Lokhu kusho ukuthi i-herring yethu ayikashintshi kakhulu eminyakeni eyizigidi ezingama-135 edlule. Ukutholwa okucashile kokuvela esikhathini sakudala bekubukeka kufana. Uxolo ama-dinosaurs ayengewona amadoda aqabile kangako, akunjalo? I-Tweet Tweet.

I-pharynx ne-swad bladder yezinhlanzi zimbozwe ngezicubu zamaphaphu, ezivumela ukuba ziphefumule umoya ojwayelekile. Amandla wezinhlanzi awamangalisa impela, yize etholakala kwezinye izinhlobo. Lesi sici se-anatomical senza isilwane siphefumule. Awukwazi ukudida imodeli yokuphefumula yomuntu omkhulu noma ubani. Ukuze uthole umoya ophefumulayo, i-arapaime ikhuphukela phezulu, imboze ubuso bayo futhi idale ithokhethi, ivula umlomo wayo kabanzi.

Kepha emuva esimeni esiyinhloko saleli khamu lamanzi ahlanzekile, usayizi waso wasebukhosini. Abantu abadala bakhulu ngendlela emangalisayo - amamitha ayi-3-4 ubude, anesisindo esingama-200 kg. I-Arapaima ingukutholwa kwangempela komdobi onolwazi. Kuze kube muva nje, izinhlanzi zabanjwa ngokungalawulwa. Kungemva kokuba inani lezinhlobo linciphile ngokuphelele, ukulawulwa kwethulwa emazweni aseNingizimu Melika.

Yini edingekayo ukondla umuntu wasebukhosini? Caruncle. Inyama ka-Aristocrat ibekwa nsuku zonke, hhayi ngezimpelasonto. Imidondoshiya idla izelamani ezincane, zidla zonke izinhlanzi zisendleleni yazo. Kwesinye isikhathi izakhamizi zasemhlabeni, ngokwesibonelo, izinyoni, ezinqume ukugeza endaweni yokubhukuda enkulukazi, nazo ziya kuyondla. Izilwane ezincane zinokunambitheka okucolisisiwe. Ukudla abakuthanda kakhulu i-shrimp yamanzi amasha. Ukufihla isidumbu esinjalo umphangi ngeke asebenze. Ekuzingeleni, inhlanzi yenza sengathi iyi-log elintantayo engahleliwe, bese yenza ijerk ebukhali empangweni yayo.

Ekhuluma ngoFry. I-Arapaims - njengeenkosi zamakhosi zangempela, zibanakekela ngokucophelela abazisebenzisayo. Isikhathi sokuzala siba ngoNovemba (ENingizimu Melika, lokhu kungukuqala kwehlobo). Iduna elikhulu nelikhuluphele lidonsa umgodi ezansi. Kuqhamuka intokazi enkulu nenonile. Uma inkosazana ithanda umgodi, khona-ke izoqala ukumjikisa amaqanda, kuthi owesilisa, njengoba kulindeleke, isidoda.

Esikhathini esingangesonto, lo mbhangqwana unakekela izingane, zixosha izinyamazane ezindleleni zokwenza imbaza. Ngemuva kokubopha izingane, ubaba uyaqhubeka nokuvikela izingane ezingozini zalo mhlaba. Ukuze izilwane ezincane ezinqamulelayo zingasabalali noma kuphi, i-ZAZHEETETS ifaka imfihlo ye-encyme ekhethekile ethambisa imfino. Ngenxa yalokhu, abancane baphansi kokugadwa njalo kukababa omkhulu. Kepha, izingane ziyakhula. Futhi emva kwezinyanga ezingama-2-3, ukupela kwe-enzyme kuyancipha, izinhlanzi esezikhulile zihamba uhambo lwamahhala.

I-Arapaima ingenye yezinhlobo ezimbalwa ezilandela ukwamukelwa kwefry esele ngaphandle kwabazali. Imidondoshiya ebambile ithatha ngisho nenzalo yayo ngaphansi kwemali, ikhulisa izingane eziyizintandane nayo. Futhi manje sibona inhlanzi ephumelelayo phambi kwethu, efinyelele ukuphakama kangangokuba izosinda eminye iminyaka eyizigidi ezingama-135 ngaphandle kwezinkinga ngaphandle kwezinguquko, kodwa. Umuntu. Umuntu uhlala njalo, uyazi.

Sekungamakhulu amaningi eminyaka, ukubamba ama-arapaims amakhulu kube ukudoba okuphambili kuyo yonke imizana ehlala kulezi zindawo. Inyama yenhlanzi icishe ibe yize, ithi, inambitheka ngendlela emangalisayo futhi ithengiswa ngemali enkulu, ngamazinga emizana edobayo, imali. Manje umbono usengozini yokubhujiswa. Ukudotshwa kwenqwaba akuvunyelwe, kodwa wena ngokwakho uyaqonda ukuthi hlobo luphi lweziphathimandla zokulawula olungase lube khona ehlathini elikude. Minyaka yonke, amachibi aya eba mpofu. Ithemba lokongiwa kwezinhlanzi ligcinwa kuphela ezindaweni ezimbalwa ezivikelwe lapho zidotshwa khona ngokukhethekile. Akekho umuntu okufanele asolwe. Abantu basinda ngendlela abangakwazi ngayo, futhi isixazululo kufanele sibe sesimweni sokuthuthuka okuphelele kwayo yonke imikhakha yempilo esifundeni.

Ngendlela, ungangithola iphutha lokuthi le akuyona empeleni inhlanzi enkulu yamanzi amasha, njengoba kukhona i-beluga yethu yaseRussia kanye nobufakazi obuqinisekisiwe bababantu abanesisindo esingaphezu kwethani. Kodwa, ngeshwa, ama-belugas amakhulu kangaka awatholakalanga iminyaka eyi-100, futhi nansi - lapha futhi manje. Amamitha amane nama-200 kg.

Nakekela imvelo nemvelo kuzokuvikela.

Incwadi Yezilwane yayinawe.

Isithupha phezulu, ukubhalisa - ukusekela umsebenzi wombhali.

Yabelana ngemibono yakho kumazwana, sihlala siwafunda.

Ukuphila endalweni

I-Arapaima (lat.Arapaima gigas) yachazwa okokuqala ngonyaka we-1822. Ihlala kuyo yonke ubude be-Amazon nezinkokhelo zayo.

Izindawo ezihlala kuzo zincike ngenkathi. Ngenkathi yemvula, i-arapaima ifudukela emachibini nasemifuleni, futhi nangesikhathi semvula, iye emahlathini ayakhukhula. Imvamisa ihlala endaweni enamanzi, lapho ijwayele ukuphefumula umoya-mpilo womoya, iwugwinye kusuka ebusweni.

Futhi emvelweni, ama-arapaim avuthiwe ngokobulili adla ikakhulu ezinhlanzini nasezinhlanzini, kepha izingane ezincane azaneliseki kakhulu futhi zidla cishe yonke into - inhlanzi, izinambuzane, izibungu, ama-invertebrates.

Incazelo

I-Arapaima inomzimba omude futhi omude ngamaphiko amabili amancane we-pectoral. Umbala womzimba uluhlaza ngombala wokuboniswa okuhlukahlukene, nezikali ezibomvu esiswini.

Unezikali ezinzima kakhulu, ezibukeka njengegobolondo futhi okunzima kakhulu ukubhoboza.

Le ngenye yezinhlanzi ezinkulu zamanzi ahlanzekile e-aquarium, ikhula cishe ngo-60 cm futhi ihlala iminyaka engama-20.

Futhi emvelweni, ubude obuphakathi buyi-200 cm, yize kunabantu abakhulu. Kunobufakazi bendawo engu-450 cm ubude, kepha ibhekisela ekuqaleni kwekhulu leminyaka elidlule futhi ayibhalwa phansi.

Isisindo esiqinisekisiwe esiphezulu singama-200 kg. Amancanyana ahlala nabazali bawo izinyanga ezintathu zokuqala zokuphila futhi afinyelela ekuvuthweni eneminyaka eyi-5 kuphela.

Umsuka wokubuka nencazelo

I-Arapaima yinhlanzi ehlala emanzini amasha asishisayo, angomndeni wakwa-Aravan kanye ne-oda le-Araranoid. Leli qembu lenhlanzi ezinamanzi ahlanzekile angabizwa ngokuthi awokuqala. Izinhlanzi ze-Aravanoid zihlukaniswa ukuphuma kwethambo okufana namazinyo akhiwe olimini. Ngokuphathelene nesisu ne-pharynx, amathumbu alezi zinhlanzi asohlangothini lwesobunxele, yize kwezinye izinhlanzi zidlula ngakwesokunene.

Ividiyo: I-Arapayma

Izinsalela zakudala kakhulu ze-Aracoids zatholakala ezincwadini zesikhathi se-Jurassic noma i-Early Cretaceous, iminyaka yalezi zinto zamalahlezi ezisukela eminyakeni eyizigidi eziyi-145 kuye kwezingu-140. Batholakala enyakatho-ntshonalanga yezwekazi lase-Afrika, endaweni yaseMorocco. Ngokuvamile, ososayensi bakholelwa ukuthi i-arapaima yayiphila ngalezozinsuku lapho ama-dinosaurs ayehlala khona emhlabeni. Kunombono wokuthi iminyaka eyizigidi ezingama-135, ngaphandle, ihlala ingashintshiwe, okumangazayo nje. I-Arapaim ingabizwa kufanele ngokuthi hhayi ifossil ephilayo nje kuphela, kodwa futhi kuthiwa yisilo esikhulu sangempela sokujula kwamanzi ahlanzekile.

Iqiniso elihehayo: I-Arapaima ingenye yezinhlanzi ezinkulu kunazo zonke eMhlabeni, ezihlala emanzini amasha, ngobukhulu bawo ziphansi kancane kunezinhlobo zama-belugas ngamanye.

Le nhlanzi enkulu emangalisayo inamagama amaningi, i-arapaim ibizwa ngokuthi:

• omkhulu arapaime
• I-Brazil Arapaim
• piraruku
• puraruk
• paye.

AmaNdiya aseBrazil aqamba igama le nhlanzi ngokuthi "pyrarucu", okusho ukuthi "inhlanzi ebomvu", leli gama ligxilisiwe kulo ngenxa yokubonga kohlelo lombala we-orange-inyama yenhlanzi kanye namabala abomvu agcwele esikalini, atholakala emsileni. AmaNdiya avela eGuiana abiza le nhlanzi ngokuthi i-arapaima, negama layo lesayensi elithi "Arapaima gigas" livela negama leGuana ngokufakwa kwesichasiso "esikhulu".

Ubukhulu be-arapaimes buyamangalisa ngempela. Ubude bomzimba wakhe onamandla bufinyelela kumamitha amabili ubude, futhi kuyaqabukela, kepha kwakukhona amamodeli akhula afinyelela kumamitha amathathu. Kunofakazi bokuzibonela abathi bahlangana nezikhathi zasendulo ngobude bamamitha angama-4,6, kepha le datha ayisekelwa lutho.

Iqiniso elithokozisayo: Isisindo se-arapaima enkulu kunazo zonke ezabanjwa sasingezikhulu ezimbili, lolu lwazi lubhalisiwe ngokusemthethweni.

Ukubukeka nezimpawu

Isithombe: Kubukeka kanjani njenge-arapime

Umzimba we-arapaim uphakeme, isibalo sonke siyaphakama futhi sithambile kancane ezinhlangothini. Ukunciphisa okubonakalayo kusondele endaweni yekhanda, nayo ephakeme. Isigaxa se-arapaim engxenyeni engenhla sithambile kancane, futhi amehlo asondele engxenyeni engezansi yekhanda. Umlomo wenhlanzi, uqhathaniswa nosayizi wawo, mncane futhi utholakala uphakeme impela.

Ingxenye yomsila we-arapaim inamandla amakhulu namandla, ngosizo lwayo inhlanzi yasendulo yenza ukuhlaselwa kombani iphonse, igxuma ikholamu yamanzi lapho ilandela isisulu. Ekhanda lenhlanzi, njengesigqoko sesondo, kukhona amapuleti amathambo. Izikali zase-Arapaimea ziqinile, njengevoti le-bulletproof, ihlukaniswe ngamatshe amaningi, inokukhululeka nobukhulu obukhulu.

Iqiniso elithokozisayo: I-Arapaima inezikali eziqinile, eziphindwe ka-10 kunamathambo, ngakho-ke amaphiraneshas amabi futhi anegazi lenhlanzi enkulu ayesabeki, bona ngokwabo kade baqonda ukuthi le Giorgia inzima kakhulu kubo, ngakho bahlala kude naye.

Cishe eduze kwesisu se-arapaima kunamaphiko we-pectoral. Ama-anal and dorsal fins mude kakhulu futhi agudlulwa eduze komsila. Ngenxa yalesi sakhiwo, ingxenye engemuva yenhlanzi ifana ne-oar; isiza i-arapaime ukusheshisa ngesikhathi esifanele futhi ihlasele isisulu sayo ngokushesha.

Ngaphambili, inhlanzi inesikimu sombala onsundu, lapho kuboniswa khona ukuthinta okuthile okuluhlaza okwesibhakabhaka. Lapho kutholakala khona amaphiko angenamikhono, ithoni yomnqumo ithathelwa indawo obomvu, kuthi lapho isondela eduze nomsila, iphenduke ibomvu ibomvu futhi igcwele, iba mnyama ngokwengeziwe. Amabhothi abomvu nawo angabonakala ezembozweni ze-gill. Umsila uhlanganiswa nomngcele obanzi wombala omnyama. Umehluko phakathi kobulili e-Arapaima ubonakala kakhulu: abesilisa banciphile futhi bancane, umbala wabo ulula kakhulu futhi uqhakazile. Futhi izinhlanzi ezincane zinombala ophelile, okufanayo kwabesilisa nabesifazane abasha.

Manje usuyazi ukuthi ukubukeka kwe-arapime kubukeka kanjani. Ake sibheke lapho kutholakala khona inhlanzi enkulu.

Ihlala kuphi i-arapaime?

Isithombe: I-Arapaim Fish

I-Arapaima ingumuntu ohlola umzimba, omangalisayo, nowangaphandle.

Wayemthanda u-Amazonia, ehlala ezindaweni ezinkulu zamanzi:

Futhi, le nhlanzi enkulu yalethwa ngamatshe emanzini aseMalaysia naseThailand, lapho yaqala khona impande. Emvelweni yemvelo, izinhlanzi zithanda izitshalo zasemfuleni kanye namachibi, lapho izimila zasemanzini ziningi khona, kepha zingatholakala nakwezinye izidalwa zamanzi ezikhukhula. Enye yezinto eziphambili zomsebenzi wayo ophumelelayo yimpilo kahulumeni yokushisa efanelekile, okufanele ihluka kusuka kuma-25 kuye kwangama-29 degrees, kunjalo, enophawu lokuhlanganisa.

Iqiniso elithakazelisayo: Lapho kufika isikhathi sezimvula, i-arapaima imvamisa ifudukela emahlathini ayizikhukhula, agcwele amanzi. Lapho isomiso sibuyela, inhlanzi ibhukuda ibuyele emachibini nasemifuleni.

Futhi kwenzeka ukuthi inhlanzi ayikwazi ukubuyela echibini layo noma emfuleni, lapho-ke kufanele ilinde isikhathi kumachibi amancane asasele ngemuva kokuchitha amanzi. Esikhathini esinamandla, i-arapime ingazingcwaba emhlabathini osilika noma ohlanzekile wesihlabathi, iyakwazi nokuhlala emazweni anodaka. Uma inhlanhla izoba ngasohlangothini lwe-pyraruka futhi ibekezelele isikhathi sesomiso, inhlanzi izobuyela echibini layo elinokuhlalwa kulo ngesikhathi semvula esilandelayo.

Kuyaqapheleka ukuthi i-arapaim ifakwe ezimweni zokufakelwa, kepha lo msebenzi unzima kakhulu. Kwenziwa eYurophu, e-Asia nase Latin America. Vele, ekudingisweni i-arapaimes ayinawo ubukhulu obunjalo, awudluli imitha ubude. Izinhlanzi ezinjalo zihlalwa ezindaweni zokudoba zasolwandle, ama-zoo, kanye namachibi okufakelwa abasebenza ngokukhiqiza izinhlanzi.

Ngabe kudliwa yiphi i-arapaime?

Isithombe: U-Arapaima, uyi-pyraruku

Akumangazi ukuthi ngosayizi omkhulu kangako, i-arapaima iyisidlakudla esinamandla kakhulu, esiyingozi futhi sishesha. Ngokuyisisekelo, imenyu ye-arapaims inhlanzi, enezinhlanzi ezincane nezinhlobo zezinhlanzi ezinesisindo esithe xaxa. Uma noma yiziphi izilwane ezincelisayo ezincane nezinyoni zikule ndawo yokungenela inyamazane, izinhlanzi ngokuqinisekile ziyothatha ithuba ukubamba isidlo esinjalo esingajwayelekile. Ngakho-ke, izilwane eza ukuzophuza amanzi, nezinyoni ezihleli emagatsheni zithambekele ukukha amanzi, zingaba ukudla kwenhlanzi enkulu.

Uma ama-arapaemes avuthiwe akhetha ngokwengeziwe ekudleni, khona-ke ukukhula okuncane kwalezi zinhlanzi kumane kungukudla okungenakuphikiswa futhi kubambe konke okuhamba kuseduze, kubambe:

• izinhlanzi ezincane
• zonke izinhlobo zezinambuzane nezibungu zazo,
• izinyoka ezincane
• izinyoni ezinesayizi ephakathi nendawo ezincelisayo,
• i-carrion.

Iqiniso elikhangayo: Enye yezitsha ezithandwa kakhulu ze-arapaima isihlobo sayo, inhlanzi ye-aravan, engeye-aravaniformes efanayo.

I-Arapaim, ehlala ezimeni zokufakelwa, idla ukudla okune-protein eningi: izinhlobonhlobo zezinhlanzi, izinkukhu, inyama yenkomo, igobolondo kanye nama-amphibians. Njengoba endle i-arapaima ilandela inyamazane yayo isikhathi eside, imvamisa ivumela izinhlanzi ezincane ukuba ziphile emanzini ayo. Izinhlanzi ezivuthiwe zidinga ukondliwa okukodwa ngosuku, kanti nezilwane ezincane zidinga ukudla kathathu ngosuku, ngaphandle kwalokho zingaqala ukuzingela omakhelwane abahlala e-aquarium yabo.

Izici zobuntu nendlela yokuphila

Isithombe: Giant Arapaima

Naphezu kweqiniso lokuthi i-arapaimea inamandla amakhulu, iyinhlanzi esebenza kakhulu, ihlala ihamba. Uhlala azifunela ukudla, ukuze akwazi ukubamba isikhashana ukuze angesabi inyamazane ayitholile noma ayeke ukuphumula okufushane. Inhlanzi izama ukuhlala isondele ezansi, kepha ngesikhathi sokuzingela ihlala ikhuphukela phezulu.

Ngosizo lomsila wayo onamandla, i-arapime ingagxuma ikholamu yamanzi iye kulo lonke ubude bayo obuhlaba umxhwele. Ngokusobala, lo mbukwane umane wethusa futhi udangele, ngoba lesi sidalwa sasendulo sifinyelela amamitha amathathu ubude. I-Arapaima ikwenza lokhu ngaso sonke isikhathi lapho ixosha inyamazane, izama ukugxumela egatsheni lesihlahla elenga phezu kwamanzi.

Iqiniso elihehayo: ngaphezulu kwesiqeshana sokubhukuda kanye ne-pharynx, i-arapaim inethiwekhi eminyene yemithambo yegazi, efanayo ngesakhiwo izicubu zamaphaphu, ngakho-ke lezi zitho zisetshenziswa yizinhlanzi njengesixhobo esengeziwe sokuphefumula, ngosizo laso esiphefumula umoya wasemkhathini ukuze siphile ngenkathi eyomile.

Lapho izidumbu zamanzi ziba ezingashoni ngokuphelele, i-pyraruku icwiliswa odakeni olumanzi noma enhlabathini enesihlabathi, kodwa njalo ngemizuzu eyi-10 kuye kwayi-15 ikhethwa phezulu phansi ukuze iphefumule. Ngakho-ke, i-arapime iphefumula kakhulu, ngakho-ke ukububula kwakhe nokuphefumula kwakhe kwezwakala esifundeni sonke. Ngokuvamile, le whopper ingabizwa ngokuzethemba hhayi nje ngokuba ngumzingeli onobuqili futhi ogugile, kodwa futhi ne-hardy ekhethekile ekhethekile.

Isakhiwo senhlalo nokuzala

Photo: Arapaim e-Amazon

Ama-arapaims angabesifazane aba ukukhula ngokocansi asondele eminyakeni yobudala emihlanu, lapho ekhula abe yimitha nesigamu. Kuvela izinhlanzi ngasekupheleni kukaFebhuwari noma ekuqaleni kwentwasahlobo. Insikazi iqala ukulungiselela isidleke sayo ngaphambi kwesikhathi. Uyihlomisa ichibi elifudumele elivilaphayo noma lapho amanzi esekhona, into esemqoka ukuthi phansi kunesihlabathi.Inhlanzi imba umgodi, obubanzi bawo busuka kwengxenye yemitha iye kuma-80 cm, kanye nokujula - kusuka ku-15 kuye ku-20 cm. Kamuva, insikazi ibuyela kule ndawo isivele ihamba nomlingani wayo futhi iqala ukuvela, okuyinto enkulu ngosayizi.

Ngemuva kwezinsuku ezimbalwa, amaqanda aqala ukuqhuma, bese kuvela uFry kubo. Ngaso sonke isikhathi (kusukela ekuqaleni kokukhula kuze kube yilapho ifreyithisi isizimele), ubaba okhathalelayo useduze, evikela, evikela futhi ondle inzalo yakhe, umama naye akabhukudi asuke esidlekeni ngaphezu kwamamitha ayi-15.

Iqiniso elihehayo: Izinsuku zokuqala zokuphila kwe-Arapaims encane zifika eduze kukababa wazo, uyazondla ngemfihlo ekhethekile emhlophe, egcinwe yizinduna ezitholakala eduze kwamehlo ezinhlanzi. Le nto inephunga elithile, elisiza gazinga ukuhambisana noyise futhi ingalahleki embusweni ongaphansi kwamanzi.

Izinsana zikhula ngokushesha, zithola cishe amagremu ayi-100 enesisindo futhi zengeza cishe amasentimitha angama-5 ubude ngaphezu kwenyanga.Izinhlanzi ezincane ziqala ukudla njengabadli bezingane ubudala phakathi nesonto, bese zithola inkululeko yazo. Okokuqala, ukudla kwabo kuqukethe ama-plankton nama-invertebrates amancane, bese kuthi ngemuva kwalokho kube nenhlanzi encane kanye nokunye okuphangiweyo kuyo.

Abazali basenezinyanga ezintathu bengasayiboni impilo yezingane zabo futhi bayabasiza ngazo zonke izindlela ezingabakhona, okungeyona into enkulu ngokuziphatha kwezinhlanzi. Ososayensi bathi lokhu kufana nokuthi izingane azikwazi ngokushesha ukuphefumula ngosizo lomoya wasemkhathini, futhi nabazali abanakekelayo bazifundisa kamuva. Akukaziwa ngokuqinisekile ukuthi mangaki ama-arapayms ahlala endle. Ososayensi baphakamisa ukuthi isikhathi sabo sokuphila esimweni semvelo sisukela eminyakeni eyisishiyagalombili kuya kwengama-10, sincike ekutheni iqiniso lokuthi ekuthunjweni izinhlanzi ziphila kusuka eminyakeni eyi-10 kuye kweyi-12.

Izitha zemvelo arapime

Isithombe: Umfula i-Arapayma

Akumangazi ukuthi i-colossus enjenge-arapaima, ezimweni zemvelo, cishe ayinazitha. Ubukhulu benhlanzi, impela, bukhulu kakhulu, futhi izembatho zayo zempi azinakufinyeleleka, ngisho nepiranhas idlula kuleli hulk, ngoba azikwazi ukubhekana nezikali zalo ezikhulu. Ofakazi bokuzibonela bathi ngesinye isikhathi ama-alligators afuna i-arapime, kepha ayakwenza kaningi, yize imininingwane ephathelene nalolu lwazi ingaqinisekiswa.

Isitha esikhohlisayo kunazo zonke i-arapaima singabhekwa njengomuntu obelokhu ezingela izinhlanzi ezinkulu kakhulu amakhulu amaningi eminyaka. AmaNdiya ahlala e-Amazonia abheka futhi asayibheka le nhlanzi njengendawo yokudla eyinhloko. Bakha iqhinga lokuthathwa kwakhe kudala: abantu bathola ukuphefumula komoya wakhe onomsindo, ngemuva kwalokho babanjwa besebenzisa inetha noma behluthulelwe.

Inyama yenhlanzi imnandi kakhulu futhi inempilo, eNingizimu Melika iyabiza kakhulu. Ngisho nokuvinjwa kokudotshwa kwe-arapaime akuyekisi abadobi abaningi bendawo. AmaNdiya asebenzisa amathambo enhlanzi ngezinjongo zokwelapha, futhi enza nezitsha zazo. Ukusuka esikalini sezinhlanzi, kutholakala amafayela amahle kakhulu wezipikili, adumile kakhulu kubavakashi. Esikhathini sethu, izibonakaliso ezinkulu kakhulu ze-arapaims zithathwa njengezisulu, konke kungenxa yokuthi amakhulu amaningi eminyaka amaNdiya angabambanga abantu abakhulu kunabo bonke futhi abanesisindo esikhulu.

Isimo sabantu kanye nezinhlobo zezinhlobo

Isithombe: Kubukeka kanjani njenge-arapime

Inani labantu base-arapaime lisanda kwehla kakhulu. Ukubanjwa kwezinhlanzi okuhlelekile nokungalawulwa, ingxenye enkulu, ngosizo lwamanethi, kuholele ekutheni eminyakeni eyikhulu edlule inani lezinhlanzi liye lehla kancane kancane. Izithambiso ezinamandla kakhulu, ezazithathwa njengendebe enomdlandla futhi zavinjwa ngokuhaha okukhulu, zithinteke kakhulu.

Manje esifundeni sase-Amazon ukuhlangana nezinhlanzi ezidlula amamitha amabili ubude kungukutholakala. Kwezinye izifunda, kwethulwe umthetho wokuvinjwa kokubanjwa kwama-arapimes, kepha lokhu akubavimbeli abazingeli abafuna ukuthengisa inyama yenhlanzi, okungabizi. AmaNdiya okudoba asendaweni aqhubeka nokuzingela izinhlanzi ezinkulu, njengoba Kusukela kudala isikhumbuzo sasidla ukudla inyama yaso.

Inhlanzi enkulu yasendulo neyasendulo ayifundelwa kabi, futhi akukho mininingwane eqondile nenembile ngenani lemfuyo yayo. Ngisho neqiniso lokuthi inani lezinhlanzi selinciphile, umcabango ususelwa kuphela kwinani lezinhlobo ezinkulu, eziqale ukuvela ngokungajwayelekile. I-IUCN namanje ayikwazi ukwahlukanisa le nhlanzi kunoma yisiphi isigaba esivikelekile.

Kuze kube manje, isikhathi se-arapime sinikezwe isimo esididayo sedatha "enganele". Izinhlangano eziningi zemvelo zithi le nhlanzi enobuhlakani idinga izindlela ezikhethekile zokuvikela, ezithathwa yiziphathimandla zezinye izifundazwe.

Njengoba sekushiwo, izinkomba ezinkulu zempikiswano ziba mbalwa kakhulu, yingakho sekusondele kakhulu ukuphela kweminyaka eyikhulu yamashumi ayisithupha edlule iziphathimandla zamazwe athile aseLatin America zifaka le nhlanzi ezincwadini ezibomvu ezindaweni zazo futhi zathatha izindlela ezikhethekile zokuvikela le ndlela eyingqayizivele. umuntu wezinhlanzi.

I-Arapaima ayiyona nje inzalo ye-gastronomic, kepha ibaluleke kakhulu kwizazi zezinto eziphilayo nakubantu bezilwane zezilwane, njengohlobo lwakudala, lwezilwane ezinwebu olusasinda ezinsukwini zethu kusukela ngesikhathi sama-dinosaurs. Ngaphezu kwalokho, izinhlanzi azisafundwa kangako. Ngakho-ke, kwamanye amazwe kunqatshelwe ngokuqinile ekubambeni i-arapaimes, nasezindaweni lapho inani lezinhlanzi likhulu impela, ukudoba kuvunyelwe, kepha ngemvume ethile, ngemvume ekhethekile nangesilinganiso esilinganiselwe.

Abanye abalimi baseBrazil bazala i-arapaima ekudingisweni besebenzisa inqubo ekhethekile. Lokhu bakwenza ngemvume yeziphathimandla futhi ukuze kwandiswe inani lezinhlanzi. Izindlela ezinjalo ziyaphumelela, futhi esikhathini esizayo kuhlelwa ukuthi kukhiqizwe izinhlanzi eziningi ekudingisweni ukuze imakethe igcwale inyama yayo, futhi ukuhlala kwe-arapaime ehlala endle akuzange kuhlupheke kulokhu futhi kwaqhubeka nempilo yayo echumayo yezigidi eziningi zeminyaka.

Ukufingqa, ngifuna ukwengeza ukuthi imvelo kamama ayikhathalelwa ukusimangaza, igcina izidalwa ezimangalisa nezasendulo njengoba arapaima. Ngokumangazayo, le nhlanzi yezinsalela yasendulo yayihlala eduzane kwama-dinosaurs. Uma ubheka i-arapaima, uhlola ubukhulu bayo obuhlaba umxhwele, awukwazi ukusiza ukuthi yiziphi izilwane ezinkulu ezazihlala umhlaba wethu izigidi eziningi zeminyaka edlule!

Imvelaphi yegama

Igama lesayensi lalezi zinhlobo Arapaima gigas kuvela igama elithi arapaima, ngakho amaNdiya aseGuyanese abiza le nhlanzi, nesiLatini gigas - "Giant", amaNdiya aseBrazil ayibiza ngokuthi i-pyrarucu, okusho ukuthi "inhlanzi ebomvu", ngenxa yombala we-orange obomvu nenyama namabala abomvu akhanyayo esikalini namaphiko angakhokhelwa.

Indawo yokuhlala nendawo yokuhlala

Kuthunyelwe eSouth America e-Amazon, eBrazil, eGuyana nasePeru. Kuhlala imifula namachibi agcwele kakhulu izimila zamanzi, emigodini nakwezinye izidumbu zamanzi ezikhukhula, emanzini okushisa kwe- + 25 ... + 29 ° C, pH = 6.0-6.5 nobulukhuni dH = 10 °. Ngenkathi yesomiso, kuhlala amachibi nemifula, ngesikhathi semvula ihamba iye emahlathini ayizikhukhula. Izinhlanzi ezingezansi.

Izinsalela ze-arapaim noma inhlanzi yezinhlobo ezifanayo nayo zitholakala eColombia esifundeni saseMagdalena futhi ingeyaseMiocene.

Indlela yokuphila

I-Predator, idla kakhulu izinhlanzi, kanye nangezinye izikhathi zezinye izilwane ezincane, kubandakanya nezinyoni. Izingela ikakhulu ebusweni bamanzi. I-Arapaim ingaphefumula umoya wasemkhathini, ngenxa yezicubu ezifakwa yinethiwekhi eminyene yemithambo yegazi, efana nezicubu zamaphaphu, ezalanisa umugqa we-pharynx kanye nesinye isinye, okubukeka kunesakhiwo samaselula futhi sisebenza njengesitho esengeziwe sokuphefumula. Le divayisi yathuthuka ngenxa yokuqukethwe komoya ophefumulwayo e-Amazon. Ngakho-ke, i-arapaima ingasinda kwisomiso ngokugwinya umoya futhi ibuyele kusilika nesihlabathi sesixhaphozi. Ukuntanta ebusweni obungaphezulu komoya njalo ngemizuzu engama-5 ukuya kwengama-20, kuzwakale umsindo womoya we-arapima omude kude.

Iba ukukhula ngokomzimba ngonyaka we-5 wokuphila, ubude bezinhlanzi zokuqala ezisakazwayo ziqala ku-160-170 kuya kuma-210-215 cm. Kuqala ngo-Ephreli-Meyi. Ifuya ezindaweni ezingashoni ngamanzi ahlanzekile nangaphansi kwesihlabathi, lapho yakha khona isidleke ngokumba umgodi ongu-50-80 cm kanye nokujula kuka-15-20 cm. Kulesi sidleke, insikazi ibekela amaqanda, amaqanda makhulu. Njengoba ingaphezulu kokwenza ukubumbana, iduna liqapha ngokucophelela amaqanda kanye nezinsana, ezidonsa ngemuva kwamahora angama-36 kuya ku-38. Ngalesi sikhathi, insikazi izungeza ngokucophelela indawo eyi-10-15 yemitha elizungeze isidleke. Ngemuva kokuqunjelwa, izibungu ziqale zihlale eduze kwekhanda lowesilisa bese zidla into ethile ekhethekile emhlophe, ekhishwa yizinduna ezikhethekile ngemuva kwamehlo ayo. Fry ikhula ngokushesha okukhulu futhi ngesonto ngemuva kokuphindwa kabusha kwe-yolk sac iba izisulu. Ngokwesilinganiso, banezela ama-5 cm ngenyanga (ukusuka ku-2,5 kuye ku-7.5 cm). Lapho ikhula kuma-aquariums eJalimane emazingeni okushisa angamamitha ayi-2323 C emva kwezinyanga eziyi-10, i-fry ifinyelela isisindo esilinganiselwe esingu-1700 g, isisindo esinamandla angama-2500 g. U-Arapaim, owayehlala eChicago aquarium, wakhula cishe ngo-1.5 m ngaphezu kweminyaka emi-5: kusuka ku-20 kufika ku-160 cm.

Izici ezihlukile zama-arapaimes noma i-piraruku

Umuntu ngamunye ohlala kulo mhlaba wethu uhlukile futhi akathandeki, futhi uma kukhulunywa ngezilwane ezinjengezinhlanzi ezinkulu zase-arapaime, ukumangala kumane kudlule. Ngeshwa, indlela yokuphila kwalezi zinhlanzi zasendulo ifundwe kancane. Imithombo esemqoka yemininingwane yizindaba zabahambi, abavame ukungathembeki. Umdabu waseNdiya waseMelika, owayesebenze iminyaka eminingi kwezokudoba e-Arapaim, akazange enze okubonakalayo ngokwesayensi. Babona kuye kuphela umthombo wokudla, ngoba inyama yakhe imnandi.

Usayizi nokubukeka

Inhlanzi ye-Arapaima noma yePayce inokubukeka okuxakile kangangokuba ngifuna ukubhekisisa cishe yonke ingxenye yomzimba wakhe, enesimo esidlulile futhi icindezelwe kusukela ezinhlangothini:

• Ikhanda liyaphawuleka futhi sengathi ligcotshwe ngaphezulu, ukuze libukeke lincane ngokusemuva komzimba omkhulu. Amapulangwe amathambo avikela ikhanda phezulu.
• Umlomo ungaphezulu futhi ubanzi kakhulu.
• Isikali sikhulu kakhulu, siqinile futhi sigqunywe ngemibala. Ububanzi bezikali zabantu abadala bungaphezu kwamasentimitha amane. Unqenqema lwesilinganiso ngasinye luhlotshiswe ngomngcele obomvu we-purplish (ngakho-ke kuthiwa yi-piraruk - inhlanzi ebomvu).

Izithombe ezimbalwa zenhlanzi ye-pyraruku etholakala ngezansi zibonisa izici ezichazwe ngenhla zokubukeka kwayo.

Isimo sezikali ze-arapaima

Ukuqina kwezikali ze-arapaima kukhulu kangangokuba akunakuzicabanga. I-modulus ye-elastic (isibonisi esingokomzimba sekhono lomzimba noma into yokuhlangabezana nokuhlanzeka ngaphansi kwethonya lamandla) yayiphindwe kayishumi kunale nkomba yethambo.

I-squam inesakhiwo esinezigaba eziningi, ngenxa yokuthi i-arapaima ikwazi ukusinda ngokuphephile, njengoba inenkampani ye-piranha natterera ezindaweni zokugcina ezincane ezihlukaniswe nomfula ngenkathi yesomiso.

Umbala namaphinifa

I-Adapa arapaima ezingxenyeni ezihlukene zomzimba inemibala ehlukene yombala:

• inhloko engaphambili lomzimba ingumnqumo onsundu, ibala ngombala oluhlaza okotshani,
• kusukela kumaphiko we-ventral, umbala womzimba uguquka kancane ube bomvu bese umsila uba mnyama obomvu.

Ukutholakala kwamaphiko kuhlukile kakhulu futhi kuyisici se-arapaima:

• Okungakhokhiwe (okuyisisekelo nokuhlaziywayo) yinde kakhulu futhi kususelwa kude kakhulu ne-caudal fin futhi kubukeka kucishe kulingana.
• Amaphini abhanqwe ngawodonga nawo akhishwa ngokubhekisele emsileni.

Ukuhleleka okunjalo kwamaphini angaphekiwe kunesizathu. Womathathu la manqobelo nesiqu esibanzi se-caudal sindawonye enza “umdwebo” osiza ngempumelelo inhlanzi ukuhlasela inyamazane - kuyinika ukushesha.

Ubude

Kukholelwa ukuthi izinhlobo ezinkulu kakhulu ze-arapaimea zifinyelele kubudeamasentimitha angama-450. Noma kunjalo, abukho ubufakazi obubhaliwe kulokhu. Ukuqagela kwamasentimitha angama-248 ubude, okwamaminithi eBrazil ngo-1978, kubhekwa njengokuqopha umlando ngosayizi.

Encwadini ethi "Pisces of British Guiana," ebhalwe nguShom Bourke ngemuva kohambo lwakhe lokuya eGuiana, olwenzeka ngo-1836, ubude bezinhlanzi ze-arapaima bungamamitha ayi-427 (amasentimitha angama-427). Kepha lesi sibalo asiwona umphumela wesilinganiso sakhe, kodwa sithathwa ezindabeni zabantu bendawo. Ngakho-ke, kungaba khona ukungabaza ngokwethembeka kwaso.

Ukuphefumula umoya wasemkhathini

I-Arapaim akuyona kuphela inhlanzi engaphefumula umoya-mpilo emoyeni. Izihlobo zakhe eziseduze kakhulu zinekhono elifanayo - ngokwesibonelo, u-Arovan, u-Arovan oyingqayizivele weplatinamu.

Ukuphila ngemizimba yamanzi engenawo umoya-mpilo kungenzeka ngenxa yesakhiwo esikhethekile sesinye sezinhlanzi zokubhukuda, esisebenza njengephaphu:

• Isinye sokubhukuda sikhulu kakhulu.
• Izindonga zesinye zisungulwa ngezicubu zamaselula, lapho kunethiwekhi eminyene yemithambo yegazi.

Ukuphefumula kwe-Arapaima gill kunikeza ingxenye eyodwa kuphela kwezinhlanu zezidingo zayo ze-oksijini, amaphesenti ayisishiyagalombili komoya-mpilo odingekayo othola umoya wasemkhathini. Ukufeza lokhu, ukudoba abantu abadala njalo ngemizuzu engu-15. intanta ibheke phezulu kwamanzi. Intsha kudingeka ikhuphukele phezulu komoya kaningi.

Ekhipha ikhanda lakhe emanzini futhi evula kakhulu umlomo wakhe, izinhlanzi zenza umsindo ongajwayelekile wokuqhafaza, ukhipha umoya kusuka esigaxeni sokubhukuda nokudweba engxenyeni elandelayo.

I-Arapaima Vulnerability

Ukuphefumula kwe- "pulmonary" kwe-arapaima kucacile kangangokuba kuyenza ibe sengozini enkulu. Umsindo owenziwe lapho uvula umlomo wakho luhlobo lwesiginali kubadobi.

Lapho inhlanzi inyukela phezulu, indawo engamanzi iguquka ibe yi-whirlpool enhle. Abadobi bamqaphela masinyane futhi baphonsa isifutho esinzima maphakathi ne-maelstrom. Akukona njalo ukushaya ilitshe.

Ngemuva kokuvela maphakathi nesichwensi umlomo waso uvulekile, i-arapaima ikhipha umoya “ophelile” ngokushesha, ithathe isikhashana, ivale umlomo ngaso leso sikhathi futhi ivele ingene ekujuleni. Lokhu kuhlala isikhathi esingaphezu kwemizuzwana.

Abadobi bathanda ukuzingela i-arapayma ngemizimba emincane emincane (efinyelela kumamitha ayi-160), lapho kulula kakhulu ukuqaphela ama-whirlpools. Futhi ngasikhathi esithile inhlanhla ingahle “imamatheke” kubo - kuzoba nokushaya ngqo kwesichotho emzimbeni womuntu ovuke ukuphefumula i-arapaims.

Ukondla

Isisulu esidla ikakhulu izinhlanzi, kepha futhi sidla izinyoni, ama-invertebrates, amagundane. Ngokusemqoka, bagxuma baphume emanzini babambe izilwane ezihleli emagatsheni ezihlahla.

Ekuthunjweni, adla ngazo zonke izinhlobo zokudla okubukhoma - izinhlanzi, izinduku nokudla okuhlukahlukene okufakwayo.

Ukondla e-zoo:

Izinsongo nokuvikeleka

Kudala, inyama ye-pyraruku beyiyisisekelo sokudla phakathi kwabantu base-Amazon, njenge-Arovana yase-Asia eseNingizimu mpumalanga ye-Asia. Kepha bathi nje lapho beqala ukusebenzisa amanetha ukukhipha kuwo, emifuleni eminingi i-arapaim yanyamalala. Ukube izinhlanzi ezinkulu kuphela zibanjiwe ngesifutho, abantu abasha baqala ukubanjwa yinetha, ngakho inani labantu laqala ukwehla kakhulu. Izinhlanzi ezinobude bamamitha amabili noma ngaphezulu zaqala ukubanjwa kakhulu.

Isimo esichazwe ngenhla sasiyisisusa sokuthuthukiswa kwezindlela zokunciphisa ukubamba, ukulwa nabazingeli kanye nokugcina amasheya. Isibonelo, kwesinye sezifundazwe ezisempumalanga yePeru, kuchazwa amachibi nezindawo ezithile zemifula lapho izimayini ze-arapaima zivunyelwe nelayisense elikhishwe nguMnyango Wezolimo.

Njengo-Asia Arovan, i-piraruk (arapaima) ibhalwe ku-CITES. Kubhalwe kuSithasiselo 2 njengesidalwa esinosongo lokuqothuka kanye nesidingo sokulawulwa okuqinile kokuhweba kumasampula aso.

Abantu abavunyelwe ukuba bathengiswe ngabantu abangaphansi kwamamitha owodwa nengxenye.

Usongo lwesibili lwe-arapaima njengezinhlobo ukugawulwa kwamahlathi. Kungani:

• Emahlathini agcwele ezikhukhula, ngesikhathi semvula, ama-pyraruku azala futhi akhule inzalo.
• Imifino iyisiphephelo sezingane, ezibhekene nengcindezi enamandla evela kwabazingeli.

Ukuzala

Umuntu wesifazane ufinyelela ukukhula ngokomzimba eneminyaka engu-5 nobude obungu-170 cm.

Ngokwemvelo, ama-arapaims avela ngesikhathi somile, kusukela ngoFebhuwari kuya ku-Ephreli akha isidleke, futhi ekuqaleni kwenkathi yemvula, i-re hatch ne-fry zisesimweni esihle sokukhula.

Imvamisa bmba isidleke ngaphansi kwesihlabathi, lapho insikazi ibekela amaqanda. Ngaso sonke isikhathi, abazali bavikela isidleke, kanti ukuthosa kuhlala ngaphansi kokuvikelwa kwabo okungenani izinyanga ezintathu ngemuva kokuzalwa.

Ukuzala

Ama-Arapaims azalanisa futhi azalwe kabusha emapulazini amachibi nasezindlini zokugcina ezifakwe ezindaweni ezihlukile zoMhlaba:

• Ukhuliswa eThailand, lapho ayethuliswa khona ukuze ilinywe, njengento yokudotshwa kwezemidlalo. Ukudoba emachibini angumcimbi othandwa kakhulu kubavakashi.
• EPeru, ezinye izidumbu zamanzi zivikelwe ukuhlela ukuzalaniswa kwe-arapaima ukuze kutadishwe i-biology yayo.
• EBrazil, i-arapaim yahlaliswa echibini elikhethekile ngethemba lokuyifunda.

Ukuzala

Ukufuya i-pyraruku futhi ikakhulukazi ukunakekela izingane kuyinqubo eshukumisa kakhulu, ekhombisa ukunakekelwa okuphezulu kwalezinhlanzi. Eminyakeni engu-5 yobudala, i-pyraruku iba nocansi. Ukuzala kabusha kwenzeka ngoNovemba, futhi ngazimbili zakhiwa ngaphambi kwesikhathi - ngo-Agasti nangoSepthemba. Kunombono ongavunyelwanga wokuthi abantu abadala bangazala kabili ngonyaka.

Lezi zinhlanzi ezinkulu zingabazali abakhathalela kakhulu. Ndawonye baqapha isidleke ngamaqanda akhulayo.

Ukusakazeka kwenzeka eduze kogu ngokujula okungajulile (cishe amamitha elilodwa nesigamu). Owesilisa ulungisa isidleke. Kucatshangwa ukuthi udonsa umgodi wokuklabeka enhlabathini yobumba ngomlomo wakhe. Ububanzi bomgodi bucishe bube yingxenye yemitha, futhi bujulile. Esidlekeni esinjalo, insikazi ifafaza amaqanda. Ayikho idatha ngosayizi nenombolo yamaqanda.

Ngemuva kokukhulelwa kokufakwa kweqanda, owesilisa uqala ukuvikela. Ihlala itholakala eduze kwesidleke. Insikazi nayo ayishiyi indawo esondele edlekeni, futhi ibhukuda ibanga lamamitha ayi-10-15 kuyo futhi idonsa izinhlanzi ezisondela kakhulu.

Ngemuva kokuvela kwefry, ubaba uyabanakekela

Ubaba piraruku uyaqhubeka nokuqapha futhi azungeze inzalo yakhe ngisho nangemva kokuqothula ama-fry kumaqanda. Kwelinye isonto, izinsana ezibanjiwe zisendaweni esidleke ngaphansi kokuqashwa kowesilisa ngokucophelela: kungaba ukuthi zigeleza ngenhla kwesidleke, noma zibekwe eceleni.

Lapho i-piraruk Fry ishiya isidleke, ihlala isekhanda likayise. Isakhamuzi saphakamisa ukuthi ngale ndlela intsha ithola “ubisi lwabazali”.

Kodwa-ke, uPapa ngeke abe nalo “ubisi”. Ekhanda lowesilisa osekhulile, kukhona indlala ekhethekile ekhombisa umunyu. Izimbotshana lokhu kuthunyelwa kuzo kungabhekelwa kuzithombe zesithombe se-pyraruka: ekhanda kukhona izihlambi ezincane ezifana nezilimi. Uma uthatha isikhulisi, ungazibona ngisho nakulesi sithombe.

Emaphethelweni ala ma-protrusion, izimbobo ezincane kunazo zonke ziyabonakala, lapho kukhululwa i-mucus. Yonke imfihlo echaza ukugcotshwa kwelenta ekhanda lowesilisa ilele entweni ekhethekile equkethwe mucus. Lento ihlala ikhanga izingane futhi izenze zibhukuda emhlambini. Ngokubambisana nowesilisa, i-fry iqala ukukhuphukela phezulu bese ikhipha umoya.

Ukuxhumana okungafani futhi okumangalisa kangaka nobaba kungahlala izinyanga ezintathu ubudala. Ngalesi sikhathi, abancane bayakhula, futhi ukuxhumana kwe-Arapai encane nomzali wabo kuya buthaka. Umhlambi uyahlukana, bese umuntu ngamunye eqala impilo yokuzimela.

Ngabe idlani i-arapaima

I-Arapaim yinhlanzi edlayo. Uma ubheka umthambo waso, uzophawula igebhezi eliqinile nomhlane onamandla womzimba onamaphiko aminyene angenabantu. Indima yalokhu kugoqeka yashiwo ngenhla njenge- "oar" enikeza ukushesha kwezinhlanzi ngesikhathi sokuhlaselwa.

Amajahidi adla ikakhulukazi ngesimbotshana samanzi amasha. Njengoba zikhula, izinhlanzi kanye nezilwane ezincane, njengezinyoni, zengezwa ekudleni kwe-arapaima. I-Arapaime ichitha isikhathi sayo esiningi ngezansi, ngakho-ke izinhlanzi ezingezansi zakha imenyu yazo enkulu. Ngokuvamile, akukho sithombe esiphelele sokudla kwalezi zinhlanzi ezinkulu ngenxa yezinhlobo ezingafundiswanga kahle.
