Ukuzihlanganisa kokuqala ngegama elithi “ushaka” kuyafana kubantu abaningi. Lezi yizilo ezinkulu zamathambo ezinamaphiko kanxantathu, amanzi anosawoti afinyelela olwandle nasolwandle. Balokhu befuna inyamazane ukuze bambulale umlomo.

Kodwa ingabe bonke oshaka bayingozi ngokulinganayo kubantu? Kuyavela ukuthi phakathi komndeni omkhulu wabashaka kukhona lezo ezithobile kakhulu, futhi ezinobungane ngisho nakubantu. Hlangana nommeli womndeni wabasiki be-mustachioed - ushaka wosana. Kunezinhlobo ezintathu kuphela zomndeni: ushizi ojwayelekile we-nanny, ushizi ovuthiwe wenanny kanye nomsila omfishane.

Indawo yokuhlala yoshaka

Ungahlangana nesibalo sabantu oshaka osogwini lwaseMelika oLwandlekazi lwe-Atlantic, noma ogwini olusempumalanga yoLwandlekazi iPacific. Oshaka ababanjwa ngemisipha bahlala emanzini oLwandle Olubomvu nolweCaribbean, nangasogwini lwaseNtshonalanga Afrika.

Oshaka baseNanny babhekwa njengezilwane eziphansi, imvamisa azihambi ngokuhamba ngesikebhe ukusuka emaphethelweni angama-60-70 metres futhi azishonile ekujuleni okungamamitha ayi-6. Babuthana emhlanjini, okulinganiselwa ukuthi ngabantu abangaba ngu-40. UManachi Shark uMustachioed bayizisulu zobusuku.

Ntambama bagibela emanzini asogwini, bembela amaphiko ngaphansi. Akuyona into evamile ukubona umbukwane omangazayo - umndeni wabasakazi be-nanny ubekwe ngemigqa komunye nomunye, futhi ubhakwe ngamagagasi amnene ageza kancane nje amaphini alezi zidlamlilo ezihle zivela phezulu.

Ntambama, bayathanda ukucasha emihumeni yamakhorali, emifantwini yamawa asogwini noma baphephele emabhaleni amatshe. Oshaka bakhetha ngokucophelela indawo ecashile bese bebuyela kuyo nsuku zonke ngemuva kokuzingela ebusuku.

Izimpawu ezifakiwe zoshaka we-nanny

Usayizi ophakathi kwabantu abadala usukela kumamitha ayi-2,5 kuya kwayi-3.5. Ushaka omkhulu kakhulu oqoshiwe we-nanny wayenobude bomzimba wamamitha angu-4,3. Ngaphandle, lo shark ubukeka ungenangozi futhi ufana ne-catfish enkulu. Ukufana okunjalo kunikezwa kuyo i-antennae etholakala engxenyeni engezansi yesihle, ngqo ngaphezu komlomo.

Benza umsebenzi onobuhlakani, basiza ekufuneni ukudla enhlabathini yolwandle. Izinkulungwane zamazinyo abukhali abukeka njengonxantathu athola umlomo woshaka ngemigqa. Ukushintsha noma yiliphi izinyo eliphumile noma elephukile, esikhundleni salokho kukhula ngokushesha. Amehlo kashaka we-nanny nxazonke alungile futhi ayatholakala ezinhlangothini zekhanda.

Ngokushesha ngemuva kwazo kukhona izifutho - isici esibonisa uhlobo lwezinhlobo zoshaka ezingezansi ezisiza ukuphefumula. Ngendlela, isici esimangazayo sabasiki be-nanny yikhono lokuphefumula ngenkathi lisaqhubeka, ngaphandle kokuvula nomlomo.

Umzimba woshaka we-nanny unesimo esilinganiselwe sama-cylindrical esinekhanda eli-denser. Amaphethelo wangemuva angaphansi ngosayizi ngaphambili, i-lobe engezansi yecaudal fin is ngokuphelele efakiwe. Use isithombe sikan Shark amaphiko we-pectoral athuthukiswe kahle abonakala kahle. Lokhu kuvumela umphangi ukuba abambelele emhlabathini ngokuqinile phakathi nesikhathi sokuphumula sasemini.

Kungani ushaka ubizwa ngokuthi yi-nanny?

Igama ngokwalo akuyona inzalo eqanjiwe. osokeni abangama-nanny. Kungani ibizwa Ingabe lolu hlobo lomhlaseli? Isizathu sisendleleni yokudla. Oshaka baseNanny abayikhiphi inyama yezinyama zabo, kodwa bayinamathela ngomlomo wabo, okwamanje njengamanje uyanda ngosayizi ngokushesha. Ngasikhathi sinye, umdlwenguli wenza umsindo obuthuntu obuthuntu, ofana nomsindo wokuqabula, noma ukushaya kwenganono okuzwakala kocelemba, ukwehlisa ingane.

Ngaphezu kwalokho, igama labo "abakhathalelayo" ushaka we-nanny nalo latholwa ngokuziphatha, maqondana nenzalo yakhe, hhayi uphawu lwabaningi boshaka. Ngokuyisisekelo, izisulu ezilambile aziphikisi ukuthola inzuzo ngisho nakubantwana bazo, kodwa cha oshaka bezingane. Kungani bengakwamukeli ukudla okunje, azikho izincazelo zesayensi.

Ngokuphambene nalokho, oshaka abangenasimanga baqapha ngokucophelela inzalo yabo, beyisiza ukuba ikhule. Kukhona enye inguqulo yemvelaphi yegama elihle kangaka loshaka. Ogwini lwaseCaribbean, lezi zilwane zabizwa ngokuthi oshaka bekati, okwathi ngolimi lwendawo zabizwa ngokuthi “nuss”, kamuva ezaguqulwa zahunyushwa ngokuthi “umhlengikazi” wesiNgisi - umhlengikazi noma umanny.

Indlela yokuphila yeNanny Shark Nutrition

Oshaka baseNanny bahlukaniswa yindlela yokuphila yokuhlala nokuhlala phansi. Izilwane ezi-phlegmatic, zokungcebeleka zingabola amahora amaningi endaweni eyodwa. Ososayensi baphakamisa ukuthi oshaka abahlaselwe ngotshani, noma kunjalo, njengabanye abamele abomndeni woshaka, abalali ngokuphelele.

Munye kuphela umoya ohlala uphumula, bese kuba omunye. Ikhono elimangalisa kangaka likuvumela ukuthi uhlale wazi njalo. Oshaka baseNanny bangabazingeli ebusuku. Futhi uma uphumula phakathi nosuku, futhi ubhakela emanzini asogwini, lezi zilwane zithanda amaphakethe, khona-ke zithanda ukuzingela zodwa.

Ukudla okuthandwayo koshaka be-baleen kukhona ama-crustaceans, ama-octopus, ama-squid, ama-mollusks, ama-urchins olwandle, i-flounder, i-cuttlefish kanye nezinye izakhamuzi ezingezansi zamanzi kasawoti. Ukwehlukanisa amagobolondo evikela ezinye izinhlobo zezinyamazane, ushaka we-nanny uhlonyiwe ngamazinyo abushelelezi, anobambo.

Ngosizo lwabo, uphula kalula izingxenye ezivikelwe zomzimba walowo ohlukunyeziwe. Ubukhulu bomlomo abuvumeli umhlengikazi ushaka ukuba agwinye inyamazane enkulu, kepha umphimbo wakhe uthuthukile impela. Lokhu ukuxazulula inkinga - ushaka we-nanny umane nje abambe inyamazane yakhe, okushiye okokugcina kungabi nalo ithuba lokubaleka.

Ukulindelwa kokuphila nokuzalelwa koshaka we-nanny

Uma izici zangaphandle zilungile impela kanti i-nanny shark ayizange iwele emanetheni okudoba, khona-ke isilinganiso sokuphila esiphakathi sisukela eminyakeni engama-25-30. Abase-Centenarians phakathi koshaka babhekwa njengezinhlobo ezinamakhaza. Oshaka bezikhala ezivulekile zeqhwa bangaphila iminyaka eyi-100. Lokhu, Yebo, kuhlobene nokushisa okukhona, futhi, ngomphumela, kunciphise izinqubo zokuphila.

Lapho ushaka ushibilika kakhulu, sifushane isikhathi esabelwe sona. Isikhathi sokuzala koshaka we-mustnyoed nanny sisekupheleni kwehlobo, ukusuka maphakathi noJuni kuya maphakathi noJulayi. Ibambe amazinyo ezinsikazi ngeziphephe, owesilisa uzama ukuguqula okhethiweyo emhlane noma eceleni kwakhe, okuvame ukuphela ngamaphiko ezilimele. Abesilisa abaningana bangabamba iqhaza ekwenziweni kokukhulelwa kowesifazane oyedwa. Ama-nanny oshaka angabezinhlobo zohlobo lwe-ovoviviparous oshaka.

Iqanda liqala ukukhula ngaphakathi kowesifazane, bese kuba yi-shark hatch, kodwa liqhubeke nokuphila ngaphakathi emzimbeni woshaka. Sekukonke, uchitha izinyanga eziyi-6 emzimbeni kanina, bese ezalwa emanzini afudumele asogwini. Ukukhulelwa okulandelayo kungenzeka kuphela emva konyaka nesigamu. Yileso sikhathi esingakanani lapho umzimba woshaka ululama futhi ulungiselela ukuqanjwa okusha.

Bobani oshaka abesabayo futhi ngani?

Umbuzo ubanzi kakhulu. Ake sithathe ushaka omhlophe njengesibonelo, njengomunye wabamele abanolaka nabakhulu kunabo bonke. Impendulo cishe akekho. Ushaka omhlophe osekhulile ubhekwa ngenhla kwekhonkolo lokudla. Abantu abasha baba izisulu zabantu abadala noma imikhomo yokubulala.

Kodwa-ke, kunobufakazi obuqoshiwe bokuhlasela komkhankayi kumuntu oshaka omhlophe. U-Orca uhlakaniphe kakhulu kunoshaka. Imvamisa basebenzisa ubuqili be-ramming ohlangothini, obabazekayo futhi baphendulela ushaka bubheke phansi. Kungashiwo ukuthi oshaka bayasaba imikhomo yokubulala, ngoba ezindaweni lapho kwakudotshwa khona oshaka abamhlophe, ngemuva kokubulala omunye wabo ngomkhomo wababulali, abanye banyamalala. Ngokusho kuka-beacons afakelwe abanye oshaka, bekucacisiwe ukuthi baya ekujuleni okungaphezulu kwamamitha ayi-500 futhi basuka ngomkhumbi ukusuka kule ndima.

Futhi, izingwenya ezihlotshisiwe zihlasela oshaka abamhlophe abadala ogwini lwaseNyakatho Australia. Amaqhinga afana nawawemikhomo yokubulala, ukushaya eceleni, namazinyo asesiswini.

Impendulo enhle 5

Kungani abantu bebulala abantu?

Ukubulawa komuntu ngumuntu kuhlale kushukunyiswa okuthile. Noma yimuphi umbulali unesisusa, ngokombono wakhe kwaba imbangela yalokhu kubulawa. Ababulali bangenziwa ngenxa yomhawu, ukuzithanda, ubutha, ngesisekelo sezinkolelo zenkolo, izinhloso zezombusazwe, inzondo yekilasi, ngenxa yokuziphindisela, ukuvikela okuthile, ukuzibulala, njll. Bonke abantu ababulala umuntu beqa umugqa othile ongabonakali, baphikisana nabo nonkulunkulu wabo. UMurder uphendukisa ingqondo yomuntu, noma ngabe unezisusa zini, konke ukubulawa okulandelayo kunikezwa kuye kalula futhi ngemizwa engaphakathi. Lokhu kubulala kwenzeka nokukhathazeka okuncane ngokungatholakali ngqo nomuntu ohlukunyeziwe. Abantu abaqeqeshiwe nabo bangambulala umuntu kalula. Umugqa ongabonakali usebuchosheni bethu, futhi uguqukela kumathuba lapho ubulala umuntu unomphela. Akunandaba noma yini eba yimbangela yokubulala, kubalulekile ukuthi ushintshe i-psyche yomuntu ngemuva kwayo.

Kubukeka kanjani

Abamele lo mndeni woshaka bafinyelela kumamitha ayi-3 ubude, izinhlamvu ezinkulu kakhulu azidluli amamitha ayi-4,5 ubude. Isisindo somzimba cishe singamakhilogremu ayi-130-150 (oshaka abakhulu kakhulu banamakhilogremu angaphezu kuka-170). Umzimba woshaka we-nanny unsundu noma umnyama. Kwesinye isikhathi kuba khona amabala amnyama emzimbeni wonke, kepha imvamisa (amabala) atholakala kubantu abasha kuphela.

Uhlala kuphi

Indawo yokusatshalaliswa koshaka be-nanny inkulu impela. Ngokuvamile zihlala emanzini oLwandlekazi i-Atlantic. Iningi lalaba shaka litholakala ogwini lwaseNyakatho naseNingizimu Melika. Bambalwa kakhulu oshaka abahlala oLwandle iPacific. Ngokuvamile, lezi zinhlanzi zithanda ukuhlala phansi kakhulu futhi zikhuphukele phezulu ebusuku kuphela ngesikhathi sokuzingela. Cishe usuku lonke ushaka lulele ngaphansi kwamatshe amakhulu, hhayi kude nolwandle, futhi luhamba kancane kakhulu. Ngokuqala kobumnyama, oshaka be-nanny bahlangana ngamaqembu ezinhlobo ezingama-20-30 bese beya ukuzingela eduze nolwandle. Ukudla okuyinhloko kwalawa oshaka ama-octopus, ama-crustaceans, ama-urchins olwandle nezinhlanzi.

Ingozi.

Oshaka baseNanny ababhekwa njengabayingozi kubantu, yize kuke kwaba nezimo zokuhlaselwa kwabantu. Abantu abanandaba nalezi zidalwa zasolwandle, ngakho-ke ushaka ngeke ahlasele kuqala (ukuze kudliwe umuntu). Cishe zonke izigameko ezaziwayo zokulimala koshaka-nanny kwakuyiphutha labantu uqobo. Isibonelo, abadobi noma abahlaseli be-scuba bazama ukuthinta ushaka, bawuhlabe noma bawubambe. Kulezi zimo, inhlanzi ngokushesha iluma umuntu owonile nganoma yisiphi isibambo.

Kuyingozi kakhulu imihlathi yoshaka we-nanny, ohlakazeke ngamazinyo amancane kodwa abukhali impela. Uma ushaka wawubamba umhlathi wawo, wawungeke usakhipha ukubamba kwawo kuze kube yilapho isisulu siyeka ukuhamba. Amacala achazwa lapho abantu bekwazile ukusindisa umuntu omunayo ngokumkhipha emanzini kanye noshaka ocijile. Ngisho nasemhlabeni, imihlathi eshaka isalokhu icindezelwe isikhathi eside.

Kungani ushaka ubizwa ngokuthi yi-nanny?

Lezi zinhlobo zivelaphi igama elingaziwa - "nannies"? Iqiniso ngukuthi oshaka abayilimi inyamazane yabo engathandeki, kodwa bancela, bandisa ngokushesha umlomo wabo. Ngasikhathi sinye, umsindo ophansi oshubile ufana nokushaya kwengane okugoqana ingane.

Ngaphezu kwalokho, ezinye izinhlobo zabashaka be-oven oviparous ziqinisekisa isimo sabo sabaqaphi abanakekelayo ngokunakekelwa okungafani nokwenzalo yabo. Ngakho-ke, oshaka bomama balengisa amaqanda ezitshalweni zasemanzini, bewaqinisa ngamalogo we-algae alukiwe ngemilomo yabo.

Ngakho-ke, amaqanda azithola esibelethweni i-impromptu, agadwe ngumama.

Ngokuvamile, oshaka abaningi be-nanny bayizinhlobo ze-ovoviviparous. Ukukhulelwa kuthatha izinyanga ezi-6. Ushaka wesifazane oyedwa ovuthiwe ungathwala imibungu efinyelela kwangama-27. Ushaka womhlengikazi ompunga uthakazeka ngendlela ehlukile yokuzala - i-intrauterine cannibalism.

Izinsikazi zalolu hlobo zinezimbotshana ezi-1, kulowo nalowo maqanda akhula kuwo. Ngokuhamba kwesikhathi, kuboshwe oshaka abasha ngaphakathi kwesibeletho kudla ozakwabo ababuthaka. Kusala ama-mbumbulu kuphela - kulokhozi ngalunye.

Ngasikhathi sinye, umama ukhiqiza amaqanda amasha, abe ukudla kwabazingeli abancane abangakazalwa. Izinhlanzi ezakhiwe ngokuzalwa zizalwa kuphela emva kweminyaka emi-2 yempilo yengane.

Ingabe i-nanny shark iyisidleke esivikelekile?

Kuyamukelwa ngokuvamile ukuthi "ama-nannies" ayizidalwa ezingenangozi, ezingenagazi. Ngabe kunjalo? Abasubathi baseNanny ikakhulukazi bazingela ebusuku, bese bechitha usuku belala emanzini angajulile noma eduze kwezixhobo ngamaqembu amakhulu.

Zidla ngama-octopus, ama-urchins wasolwandle, ama-shrimps, izinhlanzi ezincane noma imfoloko.

Emini, oshaka bavame ukubutha phakathi kwemihlambi eqinile, bese balale ngamaphiko abo asemuva avela emanzini. Ngasikhathi sinye, imvamisa aziphenduli ekuphambukeni okucasulayo nokubhukuda.

Kodwa-ke, uma umuntu ophambuka kancane nje ebamba indawo yakhe yezinhlanzi, acasule ulaka lwale nhlanzi lapho zizingela noma zihlangana, kanti ushaka osindayo onolaka uzokukhumbuza masinyane uhlobo lomhlaseli wangempela.

Unganga kanjani ushaka futhi uhlale uphila?

I-baby shark nanny ihlasele i-diver ecasulayo

OShark-nannies abanezinhlamvu ezihamba kancane babhukuda baye kumuntu okonile bese bemunca ngokushesha imihlathi emzimbeni, baze baphathwe ogwini, ungabavumeli ukuthi bavuleke. Yebo, cishe ingxenye yesithathu yokuhlaselwa ngesihluku kwe- “nannies” kucasulwa izixhaxha, kodwa kulokhu, oshaka bazihlasela.

Ngokuvamile lokhu kwenzeka ebusuku, lapho oshaka be-mustachioed amamitha amathathu besebenza kakhulu. Ngakho-ke, akumelwe sikhohlwe ngesimo sokuphanga salezi zinhlanzi.

Imvelo yabo ezolile, futhi ukubambezeleka kokuphendula koshaka be-nanny kuyabavumela ukuba bagcinwe ezindaweni ezinkulukazi. Ngaphezu kwalokho, lezi zinhlanzi, ngesimo sazo esinolaka, zithambisa ngokushesha, zilalela, futhi zivumela abasebenzi ukuba bazondle.

Kodwa-ke, ukwethemba ukuthula okunjalo akusafanele.

Bukela ividiyo - Ofundiswe ngo-nanny oshaka:

Oshaka base-Australia abangama-nanny basanda kuba sengozini yangempela yokuqothulwa. Kepha ukwanda kwanamuhla kwezinga lokushisa lamanzi oLwandle Lomhlaba kuzokwenza ukuthi abantu ngamunye bathuthele, okuzokwandisa inani lalezi zidalwa ezinesimo esihle, ezihamba kancane.

Ngakho-ke, i-phlegm kanye nemvelo ebonakalayo enhle ihlukanisa i-nanny phakathi kwabanye oshaka begazi. Kodwa ubungane nezinhlanzi eziyingozi akunakulindeleka. Yebo, ushaka we-nanny awunazo izici zokudalwa kwe-maniac. Kepha izici zomhlaseli ongase abe khona ziyimvelo.

Ukubukeka, ubukhulu

Ushaka we-mustachioed nanny mkhulu kunawo wonke emndenini wawo.. Ubude bawo bungadlula amamitha amane, futhi isisindo singafinyelela ku-170 kg. Ushaka womhlengikazi ovuthiwe mncane, ukhula ngobunzima kuze kube amamitha amathathu, kanti ushaka omfishane ongafinyeleli kubude obufika kumitha.

Igama laso - "mustachioed" - lo shark wamukela amadevu amancane amnandi, wawenza wafana ne-catfish. Imvelo ayizanga nalezi zimpondo zokuzijabulisa. Zisizakala kakhulu.

Ngosizo lwamadevu, umhluzi we-nanny "uskena" phansi ukudla okufanele. Abantu abathola amadevu bakhiwe ngamaseli abucayi kakhulu avumela ushaka ukuthi uthwebule nokunambitheka "kwezinto" zasemanzini. Lo msebenzi othuthukiswe kahle, ophelele ulinganisa i-shark-nanny ngenxa yamehlo akhe ampofu.

Kuyathakazelisa! Ushaka wesinaphi kufanele uphefumule ngaphandle kokuvula umlomo, ungashukumi ngokuphelele.

Amehlo kashaka we-nanny mancane futhi awathengi, kepha ngemuva kwawo kunesinye isitho esibaluleke kakhulu - i-spatter. Amanzi adonswa emanzini. Futhi ngalo, ushaka uphefumula ngenkathi isezansi. Umzimba woshaka we-nanny unobujamo be-cylindrical futhi unombala ophuzi noma onsundu.

Izindawo ezincane ezimnyama zihlakazeka kuyo yonke indawo ehlanganisiwe, kepha zitholakala kuphela kubantu abasha. Amaphethelo angaphambili akhudlwana kunasemuva. Futhi i-lobe ephansi ye-caudal fin igcwele ngokuphelele. Kepha amaphiko e-pectoral athuthukiswe kahle. Oshaka badinga ukuthi balale phansi, babambelele phansi.

Kuzoba nokuthakazelisa:

Isakhiwo somlomo woshaka we-mustachioed nanny siyathakazelisa: umlomo omncane nomphimbo onamandla owakhiwe njengompampu. Ushaka osamadevu awuklebuli inyamazane yawo, kepha unamathela ohlukunyezwa, futhi, uqobo lwawo, luboshelwa ngaphakathi kulo, lwenze umsindo wokushaya oshisayo, njengokuqabula, ukushwabana okushisayo kogogo onakekelayo. Ngendlela, lesi sici esibonakalayo sendlela yokondla sakha isisekelo senye inguqulo yokuvela kwegama lomzwelo uthando - ushaka we-nanny.

Ama-nannies aqine kakhulu i-toothy, ehlome ngamazinyo aluhlaza, anxantathu, anemiphetho ebambo. Basebenza kalula ngamagobolondo anzima ama-mollusks asolwandle. Ngaphezu kwalokho, amazinyo oswazi lwe-nanny aseshintsha njalo, amasha akhula emuva kwalawo ephukile noma awile.

Isimilo nendlela yokuphila

Ama-shark nannies ngokuziphatha kwawo athethelela igama elingenacala nelokuthula.

Zolile futhi azisebenzi. Emini, oshaka abahlotshiswe ngembobo bangqongqotha ndawonye emihlanjeni futhi babambe ugesi ekujuleni okujulile, obangcwatshwa ngamaphiko emhlabathini ophansi. Noma khetha ukuphumula amadwala asogwini, imifudlana yamawa asogwini, amanzi afudumele, angajulile angashoni emabhishi anamadwala. Futhi abanandaba nakancane ukuthi inhlawulo yendawo ephakeme inamathele ebusweni. Abasikiwe amadevu baphumula, balale ngemuva kokuzingela ebusuku.

Kuyathakazelisa! AbakwaNanny oshaka baphumula emaphaketheni futhi bazingele bodwa.

Ngaphezu kwalokho, ososayensi banenguqulo yokuthi lezi zidlakela azicimi ngokuphelele futhi zingalali ubuthongo obukhulu. Ngenkathi omunye umhlaba uphumule, omunye uphapheme. Lesi sici somdlwenguli ophapheme futhi sibonisa ezinye izinhlobo zabashaka.

Bangabazingeli abanokuzijabulisa nabanekhono. Ukuhamba kancane emvelweni, oshaka abahlasile basebenzise ngentshiseko inzuzo yabo.. Uhlobo lokuzingela oluhamba nobusuku lubavumela ukuba bandise ukudla kwabo ngezinhlanzi ezincane, ezinwabuzelayo futhi eziba nzima ngesikhathi sasemini, kepha balale ebusuku.

Uma kukhulunywa ngama-gastropods, oshaka abahlafunwayo bayaphenduka futhi bamunce okuqukethwe okumnandi kwegobolondo. Imvamisa ekuzingeleni laba oshaka basebenzisa amaqhinga wokungasebenzi - baqhwa phansi amakhanda abo aphakanyisiwe, baphumule kumaphinifa e-pectoral. Ngakho-ke baveza into engenabungozi kumphisi. Lapho kuvela inyamazane, umenzi-simer uvula umlomo wakhe wokubamba futhi amunce umuntu ohlukunyezwayo.

Uhlala isikhathi esingakanani ushaka we-nanny?

Uma konke kuhamba kahle empilweni koshaka we-nanny - kunokudla okwanele, izici zangaphandle ziyathandeka, futhi akazange angene emanetheni okudoba, khona-ke angaphila iminyaka engama-25-30. Lokhu kuqhathaniswa okuncane nezinhlobo zamakhaza zoshaka, ezisinda kuze kube iminyaka eyikhulu. Izinqubo zokuphila ezihamba kancane zabahlaseli basenyakatho ziyathinteka. Lapho ushaka ushibilika kakhulu, ifushane isikhathi sokuphila kwakho. Kepha oshaka mustachioed bathanda ulwandle olufudumele nolwandle.

Habitat, indawo yokuhlala

Oshaka baseNanny batholakala emanzini asezindaweni ezishisayo nasendaweni esishisayo. Bahlala oLwandlekazi i-Atlantic Ocean ngasogwini olusempumalanga yoLwandlekazi iPacific.

Zingatholakala futhi eshalofini lesiqhingi seCaribbean naseLwandle Olubomvu.

• I-East Atlantic - isuka eCamibia iya eGabon.
• I-Eastern Pacific - kusuka eCalifornia kuya ePeru.

I-West Atlantic - isuka eFlorida iye eningizimu yeBrazil. Indawo yokuhlala yabasiki be-nanny ibonakala ngamanzi angajulile. Akuvamile ukuthi lezi zidlamlilo zibhukude zisuka ogwini ziye olwandle olukhulu. Bakhonza izimbotshana zamanzi, imisele nemisele phakathi kwexhaphozi lommbila, ngamabhange esihlabathi.

Izitha zemvelo

Izitha emvelweni wemvelo walaba bantu abazonda ukuthula azikhonjwa. Imvamisa, oshaka abanjelwe umhlonyane bafa lapho bebanjiswa amanethi okudoba, noma ngesandla somuntu obuke inyama yakhe nesikhumba esinamandla. Noma kunjalo, lolu hlobo loshaka alulona inani elithile lokuhweba.

Ukudla Okuhlanganisiwe

Ama-invertebrates we-Benthic ayisisekelo sokudla koshaka we-mustachioed. Kumenyu yabo kukhona: ama-mollusks, ama-urchins olwandle, izimfudu, ama-shrimps, ama-octopus, ama-squids, ama-cuttlefish. Izinhlanzi ezincane zengezwa kulokhu kudla kwasolwandle: i-herring, i-mullet, inhlanzi yephrotheni, i-pufferfish, i-stingray, nenhlanzi ehlinzayo. Kwesinye isikhathi ama-algae nezicucu zesiponji sasolwandle nezasolwandle zitholakala esiswini sabashaka be-baleen. Kepha ngokusobala, lokhu akuyona ukudla okuyinhloko koshaka, kepha kungumphumela wecala lokufakwa kwenye inyamazane.

Ukuzalela inzalo

Isikhathi sokuvuthwa koshaka be-nanny siwela emqheleni wehlobo. Kuhlala cishe inyanga - ukusuka maphakathi noJuni kuya maphakathi noJulayi. Kuyinqubo eyinkimbinkimbi yokuqomisana nokuqopha, enezigaba ezinhlanu - ngokujwayelana kokuqala, ukubhukuda ngokufana okuvumelanayo, ukudweba ndawonye, ​​ukubamba amaphinifa e-pectoral abesifazane ngamazinyo futhi kuguqule esimweni esifanele ukuhlangana - ngemuva.

Kuyathakazelisa! Ngesikhathi sokubanjwa, owesilisa uvame ukulimaza uhlaka lowesifazane. Ekutsheni, ngamaphesenti angama-50 amacala abesilisa abaningi bahlanganyela, basizana ukubamba owesimame futhi benze ngokulandelana.
