Udrako ohlaza okwesibhakabhaka, ingelosi eluhlaza okwesibhakabhaka, umgwinya wolwandle ... Ngeke uwukholwe, kepha wonke lawa ngamagama esilwane esisodwa.

Udrako ohlaza okwesibhakabhaka ungowabashokobezi. Uhlala olwandle.

Amanzi eTropiki oLwandle Lomhlaba ngokwesiko abhekwa njengendawo yokuhlala “yolwandle”, lapho singaphetha khona ngokuthi ingelosi eluhlaza okwesibhakabhaka iyisilwane esishisayo.

Yini usayizi nokubukeka kwesibhakabhaka nodaka oluhlaza okwesibhakabhaka?

Uma ubheka isithombe ungaqonda ukuthi kungani la ma-gastropods enegama lawo. Zifana ncamashi nenyoni enamaphiko asabalele, noma imbali eluhlaza okwesibhakabhaka enamaphethini amangalisayo. Izindawo eziphuma eceleni kwezinhlangothi zomzimba kadrako ohlaza okwesibhakabhaka zibizwa ngokuthi yi-cerati.

AmaCerats anesakhiwo ngendlela yesandla esivulekile, njengokungathi iminwe ikhule ku-mollusk. Kulezi ziphumile, indlela yokugaya ukudla itholakala esilwaneni. Ngaphezu kwalokho, i-cerate yindlela yokuhlala emanzini bese ubhukuda, uhola ngokuziphilisa.

Umbala womzimba we-mollusk uluhlaza okwesibhakabhaka ngombala ohlaza okwesibhakabhaka nokumhlophe. Ubude besilwane buyehluka kusuka kumasentimitha amahlanu kuya kwayi-8.

Ukudla kadrako okuluhlaza okwesibhakabhaka

Okuxakile ngokwanele, kepha lesi sidalwa somoya siyisisulu sangempela. Imenyu yayo yansuku zonke ifaka phakathi izakhamizi ezingaphansi kwamanzi ezifana: isikebhe samaPutukezi, abafowethu - ama-gastropods, kanye ne-antomedusa ne-siphonophores.

Ukudla i-jellyfish kungilosi eluhlaza okwesibhakabhaka kusiza "ukungavikeleki" ngokumelene nobuthi obuqukethwe amaseli okugwaza. Indlela ekhethekile yokuvikela yohlelo lokugaya ukudla ayivumeli nje ukuthi ihlupheke ngokulimaza amaseli, kodwa futhi nokuyicubungula ukuze kusizakale ukuphepha kwayo. Kungakho udrako ohlaza okwesibhakabhaka engelulekwa ukuba athathe ngezandla ezingenalutho, ngoba angasebenzisa ubuthi obebuqoqwe ngaphambili kusuka kumaseli okugwaza wejellyfish ukuze azivikele.

Indlela yokuphila kadrako

Uma ukwazi ukuhlangana nalezi zibongo, lapho, kaningi, ungabona uhlangothi lwazo lwesisu. Lokhu kungenxa yobuchopho bokuhamba ngaphezulu kwamanzi. Isilwane sizigcwalisela ngamabhamuza omoya, siwagwinye, sikhuphukele phezulu emanzini bese sikhasa ngefilimu yaso yokuxineka (cishe, njengesiba se-aquarium).

Ngenxa yale ndlela yokuhamba emanzini nombala okhethekile (isisu esikhanyayo nesibhakabhaka esimnyama esimnyama), owethulwe kuye ngemvelo, i-mollusk ihlala ingabonakali kusuka emoyeni nakwavela ekujuleni.

Ukuzala

Onke amadragoni aluhlaza okwesibhakabhaka ayizidalwa eziphindwe kabili. Ngemuva kokuzalela, bobabili abalingani bazalela amaqanda abo, okuandisa amathuba okusinda kwesizukulwane esizayo. Imollusk inganamathisela amaqanda ayo kwesinye isilwane esintantayo, isibonelo, ne-andromedus.

Kukhona iqiniso elithokozisayo ngale-mollusk engajwayelekile: ngaphezu kwamaqanda ayo, udrako onsomi angazinamathisela ku-jellyfish. Kepha akagcini nje ngokubhukuda kulo, kepha futhi “uyaluma” ngalo, uma elamba. Ngakho-ke lo "umkhumbi wesikebhe" onomsebenzi "ohlanganisa konke".

Incazelo yemvelo

Udrako ohlaza okwesibhakabhaka ungowokuzalwa kwe-genus nudibranch. Lolu hlobo lwe-gastropod lubizwa nangokuthi i-glaucus noma izingelosi eziluhlaza okwesibhakabhaka. Izidalwa zihlukaniswa ngokungabikho kwamagobolondo. nokuba khona kwamagciwane wesikhumba akwesibili asezinhlangothini zomzimba futhi abonakale ngenxa yombala okhanyayo.

I-Glaucus ifana nomhlobiso we-brooch noma inyoni eluhlaza okwesibhakabhaka. Imizimba yabo emincanyana ifinyelela kubude obuyi-3-4 cm, kepha izinhlobonhlobo ezikhudlwana zingakhula zibe ngama-8 cm. Umzimba uhluka ngesimo esiminyene futhi senziwe kancane. Ekugcineni, kuyindiza impela. Kuhamba umlenze obanzi futhi owakhiwe kahle. Ingukuphakama okukhethekile kwemisipha, evulekile ngaphambili nokuthinta kuze kube sekupheleni.

Ikhanda lincane ngosayizi nodrako onsomi. I-mollusk inezinhlangothi zayo amaqembu amathathu abhangqiwe wezingalo eziyizigaxa ngendlela ephuma ngayo okwenziwe ngomunwe - ama-cerats, anjengokufana nokwakhiwa kwama-tentacle. Ngiyabonga, amadragoni aluhlaza okwesibhakabhaka abukeka emuhle futhi engajwayelekile. AmaCerates ahlukile ngobude, kepha athuthukisiwe kakhulu awo aqhamuka emuva. Lezi zingcwecwe zithuthukisa ikhono lokubhukuda le-mollusk. Isisekelo umbala womzimba wakhe siyinhlanganisela enhle:

• oluhlaza okwesibhakabhaka
• ukusikwa.

Ngasemuva, umbala ungaba nsundu noma ube mnyama okwesibhakabhaka. Amatende omlomo, ingxenye engezansi yekotini nomuzwa wokuhogela kuqokonyiswa ngombala ohlaza okwesibhakabhaka ogcwele. Isibopho esimnyama esiluhlaza sigijimela emaphethelweni e-cerat, kuthi intambo eluhlaza okwesibhakabhaka ibonakale ngasemlenzeni.

Lo mbala uvikela, ngoba ama-mollusks abukeka engabonakali emanzini. Amagagasi ngokuvamile awaphonsa ogwini olunesihlabathi. Lapho-ke zibamba iso ngokushesha, zidonsela ukunaka ngokubukeka kwazo okuhle.

Indawo yokuhlala nendlela yokuphila

Inani eliphakeme kakhulu lama-mollusks lingaqashelwa ogwini lwaseNingizimu-mpumalanga ye-Afrika nase-Australia. Akuvamile ukuba zivele emachibini aseYurophu. Lokhu kungenxa yokuthi amadragoni aluhlaza okwesibhakabhaka ahlala ezindaweni eziphila olwandle zasendaweni eshisayo. Bona, ngokungafani nezinye izinhlobo zama-gastropods, ngaso sonke isikhathi eduze kwamanzi futhi ungalokothi uhlale phansi. Isizathu sale ndlela yokuphila ukuthathwa ngezikhathi ezithile kwamabhamuza womoya. Bawela esiswini sengelosi eluhlaza okwesibhakabhaka, ngenxa yalokho agcinwa ngayo.

Kule vidiyo uzofunda kabanzi ngale mollusk:

Ngesikhathi sokunyakaza, ingemuva komhlali wasolwandle usesimweni esingezansi, kanti umlenze unamathela ngokuqinile ebusweni bamanzi. I-equilibrium isabalalisa umzimba we-mollusk ubheke phansi. Ihamba eduze nefilimu yokungezwani kwengqondo ifuna okuphakelayo.

Udrako ohlaza okwesibhakabhaka uyi-mollusk, umbala nemodi yokuhamba yawo ngokusebenzisa indawo yamanzi kudala ukungabonakali kwayo emanzini nasemoyeni. Isidalwa sivame ukulalela intando yomoya namagagasi. Isisu esiluhlaza okwesibhakabhaka noma esiluhlaza okwesibhakabhaka senza kungabonakali ezinyoni, kuthi emuva kube ngwevu - empilweni yasolwandle.

Ukudla

Isidalwa esinomoya omnandi nesithandekayo empeleni singumhlaseli. Le mollusk eyingozi kakhulu, ebeka usongo oluyingozi kwabanye abahlali basolwandle. Ukudla kwakhe akujwayelekile futhi kuyakhethwa. Kuqukethe izidalwa ze-hydroid ezivamile endaweni ye-glaucus. Ama-mollus angabizwa ngokuthi ama-cannibals, ngoba adla uhlobo lwawo. Ukudla okuthandekayo kwengilosi eluhlaza okwesibhakabhaka yile:

• izikebhe ze-portuguese
• antomedusa.

Abamele laba bangabahlali abanobuthi bezilwandle nolwandle. Ubuthi babo buyingozi kakhulu ebantwini, kepha kuma-mollusks alunangozi ngokuphelele. Udrako ohlaza okwesibhakabhaka uboniswa uhlelo lokugaya olungandile, amagatsha awo angena ekujuleni kwe-cerat. Ngenqubo yokudla i-jellyfish enobuthi, izinto eziyingozi ziqongelela ezithweni ezikhethekile zokugaya ukudla. Ubuthi buhlala emgedeni ogwazayo wejellyfish futhi isikhathi eside ugcina impahla yawo ebulalayo ngaphakathi kukadrako.

Ubuthi lobu, obuqokelele ngaphakathi kukadrako ohlaza okwesibhakabhaka, buba yingozi kakhulu ukwedlula lokho kwe-jellyfish. Kubeka engcupheni enkulu impilo yezinye izidalwa zasolwandle. Ngalesi sizathu, i-glaucus izizwa iphephe ngokuphelele, ngoba akekho umuntu oyodlayo.

I-Shellfish idla ngokuthakazelisa kakhulu. Lapho bebona i-jellyfish, babhukuda kuyo futhi, sebeshonile, babambelela phansi. Iluma iqatha lenyama bese ibhukuda kanye nesisulu. Ngakho-ke ziyahamba, ziluma izingxenye zize zigcwale ngokuphelele. Izinsalela ze-jellyfish zisetshenziswa njengesixwesi sokuzala.
