Ke hoʻololi mau nei i ka hohonu o ka moana, ua hoʻopio nā eels ultra-ʻeleʻele i ka poʻe noiʻi me he mea lā e ulu ana lākou i mea e hoʻohana ai i ke ʻano o ka camouflage. Me ko lākou huelo ʻālohilohi, hiki i nā ʻeli ke hoʻokokoke i kā lākou mea pio ma mua o ka ʻai ʻana iā lākou me ko lākou mau ʻāwae weliweli.
Ua hōʻike ʻia ka nānā ʻana o nā ʻano Anguilloidei (me nā ʻeli wai hou, nā ʻili spaghetti a me nā ʻeli onejaw transparent) ua ulu kūʻokoʻa ka puaʻa ʻeleʻele ma mua o hoʻokahi manawa. ʻO nā laʻana o ia ʻano, ʻo ia nā kūpuna o ka ʻili pelican (Eurypharynx pelecanoides), ʻeleʻele ale, puhi huelo bobtail, puhi ʻōniʻoniʻo, a puhi ʻili.
Ua paʻi ʻia nā ʻike o kahi noiʻi hou ma ka puke pai Kaiaolaola o na i'a ma Iulai 11, 2020, e hāʻawi ana i ka hoʻomaopopo maikaʻi ʻana i ke ʻano o nā mea kai hohonu, ʻaʻole i aʻo nui ʻia ka nui o ia mau mea.
ʻOiai ʻo ka moana hohonu ka mea nui loa o ka honua i ka honua, ʻike mākou i ka liʻiliʻi loa e pili ana i ia mea, e like me Mike Ghedotti, he polopeka o ka biology moana a me ka ichthyology ma Regis University ma Denver. Ua ʻike pū ʻo ia he hana pipiʻi ke ana ʻana i ke kai hohonu a ʻaʻole like ia me ke ana ʻana i ke kai pāpaʻu.
Noho maʻa a ʻimi ʻo ka bathypelagic, a i ʻole ke kai hohonu, i ka hohonu o ka “Midnight Zone” o ka moana, ma waena o 3,300-13,100 kapuaʻi (1,000-4,000 mika) kahi hiki ʻole ke komo ka lā. ʻO kēia pōʻeleʻele mau i hoʻololi i ke kino o nā ʻele ma nā ʻano ʻano ʻē, me ka waha o ka pelican eel he kumu hoʻohālike maikaʻi loa o ka hiki ʻole ke hoʻohālikelike ʻia e nā ʻano ʻano ʻē aʻe. ʻO ka noiʻi ʻana i nā hana a kēia mau mea i loko o ia mau mea i hōʻike ʻia he paʻakikī loa.
I ka hoʻāʻo ʻana e wehewehe i ke ʻano pohihihi o nā ʻeli kai hohonu, ua nānā pono nā mea noiʻi i ka ʻili o ka ʻili pelican ma lalo o ka microscope. I ka nānā ʻana, ʻike ka poʻe ʻepekema i kahi pigmentation ʻeleʻele jet-ʻeleʻele i laha ma nā kino kino o nā mea ola.
Ua hōʻike ʻia nā noiʻi ʻana i nā ʻano tuna ʻē aʻe he ʻano ʻeleʻele ʻeleʻele like ʻole ka ʻeleʻele ʻeleʻele like ʻole o nā ʻano tuna bathypelagic e like me ka swallower eels a me ka bobtail snipe eels, akā ʻo ka ʻili pelagic wai hohonu, e like me ka ʻili snipe a me nā ʻili niho ʻili, e noho ana i nā wai pāpaʻu, ua emi iki ka degere. o keia puaa.
I kēia mau lā, no ka manawa mua, ua hopu ʻia ka puhi pelican i ka pahu pahu me ka meaʻai i loko o kona ʻōpū. ʻOiai ʻaʻohe ona akamai i ka ʻauʻau, manaʻo ʻia ua hoʻohana kēia mau mea i ko lākou huelo bioluminescent ma ke ʻano he lawaiʻa e huki ai i nā crustaceans liʻiliʻi a i ʻole he hee, a laila lākou e ʻai ai.
ʻO ka puaʻa ʻeleʻele o kēia mau mea pupule e hiki ai iā lākou ke hoʻohana i ka bioluminescence i mea e pono ai lākou, e hoʻohālikelike ʻia nā ʻaoʻao huelo o nā ʻili pelican a me nā ʻili swallower e like me nā kukui ʻālohilohi i ka pōʻeleʻele. Ke hoʻomake ʻo ka puhi pelika i kāna meaʻai a kokoke, hiki i kona waha ke hoʻonui i ʻelima paʻi a ʻai ʻo ia i kāna pahu hopu i ka ʻai hoʻokahi.
Ua ʻōlelo ʻo Ghedotti he mea nui i ka hoʻowalewale ʻana i ka mea pio me ka māmā ʻaʻole ʻike ka holoholona i ke alo o ka mea ʻaihue ma waho o ka lure. Eia kekahi, aia nā ʻano like ʻole e hoʻohana ʻia ai ka bioluminescence ma waena o nā ʻano iʻa like ʻole ma waho o ka hoʻohana ʻana iā ia e hoʻolulu i ka mea pio, a ma ka hapa nui o ia mau hihia, ʻoi aku ka maikaʻi inā ʻaʻole hōʻike kāu luminescence i ke ola o nā ʻāpana ʻē aʻe. kou kino.
Ua paʻi mua ʻia ke aʻo ʻana ma ka puke pai Kaiaolaola o na i'a ma ka lā X XUMUM, 18.
