Izici nendawo yokuhlala
I-Manta ray yisilwane esinomgogodla, esisodwa sohlobo, esinamabhangqa amathathu emilenze esebenzayo. Ububanzi bameleli abakhulu bezinhlobo bungafinyelela kumamitha ayi-10, kepha kaningi kunabantu abaphakathi nendawo - cishe amamitha ama-5.
Isisindo sabo siyashintshashintsha cishe amathani ama-3. NgeSpanishi, igama elithi "stingray" lisho ingubo, okungukuthi, isilwane sathola igama laso emzimbeni waso ongajwayelekile. Indawo yemvelo stingray manta - amanzi apholile, asezindaweni ezishisayo nakwezifudumele. Ukujula kuyahlukahluka kakhulu - kusuka ezindaweni ezingasogwini kuya kumamitha ayi-100-120.
Ngokuvamile kwamukelwa ukuthi izici zomzimba nesimo esingajwayelekile somzimba zivumela i-manta ukuthi yehlele ekujuleni okungaphezu kwamamitha ayi-1000. Ngokuvamile, ukubonakala kwama-stingray eduze nogu kuhlotshaniswa nokushintsha kwezinkathi nesikhathi sosuku.
Ngakho-ke, entwasahlobo nasekwindla, ama-stingray ahlala emanzini angajulile, ebusika ayabhukuda olwandle oluvulekile. Into efanayo iyenzeka ngokushintsha kwesikhathi sosuku - emini, izilwane zisondele ngaphezulu, ebusuku zigijimela ekujuleni. Umzimba wesilwane uyi-rhombus ehambayo, ngoba amaphiko aso ahlanganiswe ngokuthembekile nekhanda.
I-Manta ray esithombeni kusuka phezulu kubukeka njengendawo eyisicaba elele eshibilika emanzini. Ngasohlangothini kuyabonakala ukuthi "indawo" kuleli cala ihambisa umzimba ngamagagasi futhi inyuse ngomsila omude. Umlomo we-manta ray utholakala engxenyeni yawo engenhla, okuthiwa emuva. Uma umlomo uvulekile, kuba khona "umgodi" emzimbeni we-stingray, cishe ububanzi obuyimitha elilodwa. Amehlo asendaweni eyodwa, ezinhlangothini zekhanda aphume emzimbeni.
Esithombeni, i-manta ray enomlomo ovulekile
Ingaphezulu langemuva limnyama ngombala, imvamisa linsundu, luhlaza okwesibhakabhaka noma mnyama. Isisu siyakhanya. Kukhona futhi izindawo ezivame ukuba mhlophe ngemuva, ezimeni eziningi ezisesimweni samahuku. Kukhona nabamele abamnyama ngokuphelele bezinhlobo, okuwukuphela kwendawo ekhanyayo lapho kunendawo encane engxenyeni engezansi.
Uhlamvu nendlela yokuphila
Ukuhamba kwemisebe ye-manta kwenzeka ngenxa yokuhamba kwamaphiko ahlanganiswe nekhanda. Ukusuka ngaphandle, kubukeka njengokundiza kokungcebeleka noma ukukhuphuka ngaphezu kwendawo engezansi kunokubhukuda. Isilwane sibukeka sinokuthula futhi sikhululekile, noma kunjalo usayizi we-manta ray kusenza umuntu azizwe esengozini eduze kwakhe.
Emanzini amakhulu, imithambeka ihamba ikakhulukazi emzileni oqondile, igcina ijubane elifanayo isikhathi eside. Ngaphezulu kobuso bamanzi, lapho ilanga lifudumeza khona ubuso, ithambeka lingazungeza kancane.
I-manta ray enkulu kunazo zonke ingahlala yodwa ngokuphelele kwabanye abameleli bezinhlobo, futhi ingahlangana ngamaqembu amakhulu (kufika kubantu abangama-50). Imidondoshiya ihlangana kahle eduze kwezinye izinhlanzi nezilwane ezincelisayo ezingezona ubudlova.
Ukugxuma kungumkhuba othakazelisayo wezilwane. Imanta ray igxuma iphume emanzini futhi ingenza ngisho nokuqubuka komzimba ngaphezulu kobuso bayo. Kwesinye isikhathi lokhu kuziphatha kukhulu futhi ungabona ukuhlangana okulandelayo noma ngasikhathi sinye kwama-mantas amaningi ngasikhathi sinye.
Ngeshwa, ososayensi abanayo impendulo eqondile lapho uthando lokugxuma luhlobene nomkhakha wokuphila. Mhlawumbe lokhu kwehlukile komdanso wokukhwelana noma umzamo olula wokulahla ama-parasites.
Enye iqiniso elithakazelisayo mayelana ne-manta ray ngukuthi lesi sidlakela kumele sihlale sihamba, njengoba ingwane ingathuthuki. Ukunyakaza kusiza ukumpompa amanzi ngemigodi.
Imvamisa i-giant manta ray iba isisulu soshaka abakhulu kakhulu noma imikhomo yokubulala. Futhi, ukwakheka komzimba we-stingray kwenza kube lula ukuba yizisulu zezinhlanzi eziyizinambuzane nama-crustaceans. Kodwa-ke, izimuncagazi aziyona inkinga - imisebe ye-manta izwa ngokweqile bese iyahamba iyofuna ababulali bama-parasites - imfanzi.
Ososayensi basikisela ukuthi indawo Likuphi i-manta rayibonakala kuye njengebalazwe. Ubuyela emthonjeni owodwa ukuyokhipha ama-parasites, futhi uhambela njalo izindawo ezinokudla okuningi.
Ukudla
Cishe noma yiziphi izakhamuzi zomhlaba ongaphansi kwamanzi zingaba yizisulu zemisebe ye-manta. Abamele izinhlobo ezincane ezondla izikelemu ezahlukahlukene, izibungu, ama-molluscs, ama-crustaceans amancane, bangabamba izingwane ezincane. Okungukuthi, i-manti emaphakathi nencane esencane imunca ukudla okuvela ezilwaneni.
Kubhekwa njengokuphikisana ukuthi ama-stingray amakhulu, esikhundleni salokho, adla kakhulu nge-plankton nezinhlanzi ezincane. Idlula amanzi ngokwawo, i-stingray iyayicwenga, ishiya inyamazane ne-oksijini incibilika emanzini. Ngenkathi "izingela" i-plankton, i-manta ray ingakwazi ukumboza amabanga amade, yize ingathuthukisi isivinini esisheshayo. Ijubane elijwayelekile ngu-10 km / h.
Ukuzala kanye nesikhathi sokuphila
Uhlelo lokuzala lwama-stingray luthuthuke kakhulu futhi luyinkimbinkimbi. Imisebe yeManta izala kabusha ngendlela e-ovoviviparous. Umanyolo wenzeka ngaphakathi. Owesilisa ukulungele ukukhwelana lapho ububanzi bomzimba wakhe bufinyelela kumamitha ayi-4, imvamisa ufinyelela lolu sayizi eneminyaka engama-5-6. Insikazi encane ingamamitha angu-5-6 ububanzi. Ukuvuthwa kwezocansi kuyafana.
Imidanso yokukhwelana yama-stingray nayo iyinqubo eyinkimbinkimbi. Ekuqaleni, owesilisa oyedwa noma ngaphezulu aphishekela owesifazane oyedwa. Lokhu kungaqhubeka isigamu sehora. Owesifazane ngokwakhe ukhetha umlingani ozohlangana naye.
Lapho nje owesilisa efika kokhethiweyo, uphendulela isisu sakhe phezulu, ambambe ngamaphiko. Owesilisa bese efaka ipipi ku-cloaca. Ama-stingray athatha lesi sikhundla kungakapheli imizuzu embalwa, lapho ukukhulelwa kwenzeka khona. Kubikwe amacala lapho kukhuleliswe khona abesilisa abaningi.
Amaqanda avundiswa emzimbeni wowesifazane futhi amawundlu aqandusela lapho. Ekuqaleni, badla izinsalela ze "shell", okungukuthi, i-gall sac, lapho amaqanda esesimweni semibungu. Lapho-ke, lapho lokhu kuphakelwa sekuphelile, baqala ukuthola izakhamzimba obisini lwebele.
Ngakho-ke, imibungu ihlala emzimbeni wowesifazane isikhathi esingangonyaka. I-stingray ingazala izinyane elilodwa noma amabili ngasikhathi. Lokhu kwenzeka emanzini angajulile, lapho ahlala khona aze athole amandla. Ubude bomzimba we-stingray encane bungafinyelela kumamitha ayi-1.5.
