Ilwazi Elivamileko

Umndeni omkhulu wama-Chelonioidea wakhiwe mindeni emihlanu kuthi emithathu yakhona seyatjhabalala. Yoke imihlobazo iphefumula umoya. Zimhlobo ophuma phambili ngokuthaya. Ziphumula nofana zilalae ngaphasi kwamanzi ama-awara ambalwa. Zinedlala elinetswayana ehlokwazo nelisebenza ukuphungula ubunengi betswayi ezilithola nazidlako. Ziphila isikhathi esingaba minyaka ematjhumi abunane. Zihlanganela ukumithisana elwandle, kodwana zibekelela amaqandazo ebaleni lesanda.

Zibekela amaqanda angaba ma-200 esithukghwaneni sinye. Zibekela iinthukhgu ezingabalelwa ukusuka kesisodwa ukuya kezibunane ngokwesikhathi sonyaka. Ubulili bamadzinyanazo bukhethwa bunjalo bomtjhiso wesanda esidlekeni. Amadzinyana azenzela yawo indlela yokubuyela emalwandle. Madzinyana angaba maphesende ali-0,2 % akghona ukusinda bekabe madala.

Ukudla Kwazo

Ziphila ngokudla ngemanzini ukuyela lapho kutjhingela ngamamitha amatjhuni amahlanu. Zimhlobo odla koke ngokungakhethi begodu zidla nemihlobohlobo yeemilo, iinlwanyana zangemanzini. Okufaka hlangana ama-sponges, cnidarians, molluscs, crustaceans, algae, iimilo kanye neemfesi.

Zizwana nokudla khulu imihlobo yeemfesi ezibizwa ngama-Jellyfish (cnidarians). Iitjhwaratjhwara zivame ukuphazamisa iinlwanezi ziqabange bonyana mhlobazo weemfesi eziwuthandako, nekuvamise bonyana zigcine ngokufa ngemva kokuzidla.
