Ukuqala emaphethelweni eshalofu lamazwekazi, kungashiwo ukuthi lingena ku- ekujuleni okukhulu, ebonakala ngokungabi khona kokukhanya. Yi- indawo ye-bathyal, okubandakanya nomthambeka wezwekazi, kulandelwe indawo ethafeni elingenamkhawulo elinamamitha angaphezu kuka-3.000 XNUMX, nendawo eyi-hadal, ejwayelekile yemisele yaseMariana.
Lezi zindawo ezijulile zine- ampofu ichthyofauna yasolwandle ngenxa yokushoda kokudla, ukuminyana komoya-mpilo ophansi, izingcindezi eziphakeme kakhulu kanye nezinga lokushisa eliphansi kakhulu.
EMedithera, ukwehla kuphawuleka kakhulu, Ngaphezu kwamamitha ayi-1000 ukujula kuphela izinhlobo ezingama-36 ezirekhodiwe de peces. Izici zemvelo ezinzima kakhulu zibhebhethekiswa kulolu lwandle ngenxa yokujula kweStrait of Gibraltar, evimbela ukudlula kwezinhlobo ezijulile ezisuka e-Atlantic.
I-Las izinhlobo ze-mesopelagic kanye ne-bathypelagic, ziphakathi kuka-200 no-1000 m, zinokuma okungajwayelekile noma okungajwayelekile okuphambuka kakhulu kulokho okuyiyona nqondo efanelekayo yenhlanzi ejwayelekile. Isibonelo esihle salesi morphology esingajwayelekile yi inhlanzi yezembe. Iningi de peces Kulokhu kujula okukhulu ahlome ngezitho ezikhanyayo noma ama-photophores, angasebenza kokubili ukuqashelwa kwe-intraspecific nokuheha inyamazane engenzeka.
Ngokuvamile, mancane ngosayizi. Kukhona, noma kunjalo, ukwehluka okuphawulekayo, isibonelo, 'regalecus glesne'ingafinyelela futhi yeqe ngisho amamitha amathathu ubude. Imindeni ejwayelekile ye-mesoplegic, phakathi kokunye, yiyona sibusiso, the scrawny, the ama-gonostomatids, the kubukhali futhi i izipho.
Eziningi zalezi zinhlanzi zikhombisa ukufuduka okuqonde mpo okuphawulekayo, futhi hambisa ebusuku kumazinga we-epipelagic. Abanye bafika ebangeni elingamamitha ayi-1000 ebusuku, ukufuduka okumi mpo kwebusuku okuphakathi kwamamitha angama-300 kanye nama-700 kujwayelekile kakhulu kuma-myctophids amaningi.
I-Las Izinhlobo ze-betonic yale ndawo imvamisa itholakala ngaphezu kwe-1000 m yokujula. Phakathi kokujula okungu-2.000 3.000 no-XNUMX XNUMX m, inani eliphelele lezinhlobo zezilwane lincishiswa laya kweziyisikhombisa kuphela eMedithera.
