Izilwandle ziyisistimu yemvelo enkulu kunazo zonke emhlabeni, ehlanganisa indawo enkulu yoMhlaba. Amanzi olwandle ayikhaya lenqwaba yezilwane: kusuka ezintweni ezincane ezinengqamuzana elilodwa kuya emikhomeni emikhulu eluhlaza okwesibhakabhaka. Indawo yokuhlala enhle yazo zonke izinhlobo zezilwane yathuthukiswa lapha, futhi amanzi agcwele umoya-mpilo. IPlankton ihlala emanzini angaphezulu. Amamitha okuqala ayisishiyagalolunye wokujula ezindaweni zamanzi agcwele izilwane ezahlukahlukene. Ukujula, kumnyama phansi olwandle, kepha ngisho nasezingeni lamamitha ayizinkulungwane ngaphansi kwamanzi, amathumba empilo.
Ngokuvamile, ososayensi bathi izilwane zasolwandlekazi zifundwe ngaphansi kuka-20%. Okwamanje, sekukhonjwe izinhlobo zezilwane eziyizigidi eziyi-1.5, kodwa ochwepheshe balinganisela ukuthi cishe izinhlobo eziyizigidi ezingama-25 zezidalwa ezahlukahlukene zihlala emanzini. Zonke izigaba zezilwane zinokuphikisana kakhulu, kepha zingahlukaniswa ngamaqembu.
Izinhlanzi
Isigaba esichichima kakhulu sabahlali basolwandle yizinhlanzi, ngoba zingaphezu kwezinkulungwane ezingama-250 zazo, futhi unyaka nonyaka ososayensi bathola izinhlobo ezintsha, ngaphambili ezazingaziwa muntu. Izinhlanzi ezifela emithini ziyimisebe noshaka.
I-Stingray
Ushaka
Ama-stingray amise okomsila, amise okwedayimane, ugesi, amise okwenhlanzi. Tiger, Blunt, Long-winged, Blue, Silk, Reef shark, Hammerheads, White, Giant, Fox, Carpet, Whale shark nabanye babhukuda olwandle.
Ingwe kashaka
Ushaka we-Hammerhead
Imikhomo
Imikhomo iyona emele kakhulu izilwandle. Zingezesigaba sezilwane ezincelisayo futhi zinezinto eziphansi ezintathu: okumelwe kwenziwe ngamazinyo, ezinamazinyo nezindala. Kuze kube manje, izinhlobo ezingama-79 zama-cetaceans ziyaziwa. Abamele abadume kakhulu:
Umkhomo oluhlaza okwesibhakabhaka
I-Orca
Umkhoma wesidoda
Okumthende
Umkhomo ompunga
Umkhomo i-humpback
Umkhomo weHering
Belukha
IBelttooth
UTasmanov wakhamisa ngomlomo
Indadi yaseNyakatho
Ezinye izilwane zasolwandle
Omunye wabameleli abayimfihlakalo, kepha abahle bezilwane zasolwandle ngamakhorali.
Amakhorali
Ziyizilwane ezincane ezinamathambo e-limestone ahlangana abumbe amatshe ama-coral. Iqembu elikhulu ngokwanele ngama-crustaceans, abalelwa ezinhlotsheni ezingaba yizinkulungwane ezingama-55, phakathi kwazo okukhona ama-crayfish, ama-lobster, ama-shrimps nama-lobster atholakala cishe yonke indawo.
Isikhuphashe
AmaMolluscs angamathambo angenamqolo ahlala kumagobolondo awo. Abamele leli qembu ngama-octopus, izimbaza, izinkalankala.
Ingwane
I-Clam
Emanzini abandayo olwandle, atholakala ezigxotsheni, ama-walrus, ama-seal, nezimpawu zezinwele zitholakala.
UWalrus
Izimfudu zihlala emanzini afudumele. Izilwane ezithakazelisayo zoLwandle Lomhlaba zingama-echinoderms - i-starfish, i-jellyfish nama-hedgehogs.
I-Starfish
Ngakho-ke, kuzo zonke izilwandle zomhlaba zihlala inamba enkulu yezinhlobo, zonke zihluke kakhulu futhi ziyamangalisa. Abantu kusamele bahlole lo mhlaba ongaqondakali ongaphansi kwamanzi woLwandlekazi Lomhlaba.
