ʻO Shark Cook ka poʻo nui, a he manuʻala liʻiliʻi liʻiliʻi hoʻi i ʻike ʻia i nā makika o ka genus Cephaloscyllium. ʻO kēia iʻa i hoʻākāka hou ʻia nei, ma 2008. The species epithet "Cooki" kipa ʻia i kēia hiwa e hoʻohanohano ai i ka loea kaulana ʻo Sid Cook.
Hemo loa ka Cook Shark e pili ana i kahi wahi liʻiliʻi i ke kai o Arafura, ma waena o Australia ʻĀpana me nā Tanimbar Islands (Malay Archipelago, Indonesia). No ka noho ʻana, koho i nā wahi me ka lāʻau o lalo o ke kai, he ʻulepau a i ʻole hoʻopili ʻia i lalo o ka lepo. I ka hapanui o ka manawa, ua loaʻa kēia mau hiʻona i ka hohonu o 220-300 m.
Aia nā ʻano ʻāpana i loko o nā ʻuhane haʻahaʻa. ʻO ka lōʻihi kiʻekiʻe i hoʻopaʻa ʻia o kahi kanaka he 29.5 cm.
Hōʻike ʻia ka hiʻohiʻona e kahi kino ākea ke ākea, ʻo ka laulā o ka hiki i ka 10,5-12.2% o ka lōʻihi, pōkole, pālahalaha a i hoʻāliʻi ʻia mai luna mai ke poʻo. Hoʻokomo ʻia ʻo Rostrum, pōkole. ʻO ka laulā ka lapalapa (a hiki i ka 3,4% o ka lōʻihi o ke kino), ma nā ʻaoʻao o nā ihu he mau lōʻihi nā maka a kahi e komo ʻole ai i ka waha. He lōʻihi ka waha, ʻaʻohe kālima pūʻali. I kēlā me kēia pāpale, 48-62 ʻekolu mau niho niho vertex me kahi kiʻekiʻe o ke kikowaena kiʻekiʻe a kau nā niho lateral liʻiliʻi. Nū ʻia nā niho o ka iwi luna ma luna me nā waha o ka maka. ʻO nā maka he lewa kuapoʻi, e kū ana ma luna o ke poʻo. Holoi nā haumāna o nā maka.
ʻO nā kiko o ka pectoral i liʻiliʻi liʻiliʻi, me nā ʻōlelo aʻoaʻo koʻikoʻi. ʻOi aku ka nui o ka fin dorsal anterior a ʻoi aku ke kiʻekiʻe o ka posterior. Hoʻomoʻa ʻia nā ʻōlelo aʻo o dinsal fins. ʻO ka peni anal ka mea like me ka huluhulu dorsal hope, akā heʻuʻu ka mea nui aʻe ma mua o ia mea. He liʻiliʻi nā loika Pelvic, me nā ʻōlelo aʻoaʻo. Ma nā kāne, he lōʻihi loa ka pvgvodia o ka pelvic.
Hoʻopau ka moni caudal i kahi puʻu haʻahaʻa haʻahaʻa. Ma ka kihi o ka pa o luna, aia kahi ʻano o ka ventral notch e hana ana i kahi pennant.
Kahi lili ka plactoid i ka ʻili i ka hiʻona. Ke poʻo hina-ʻulaʻulaʻula nā kino me 8 mau hiʻohiʻona pōkole ʻeleʻele e uhi ana i ke kua a me kahi o nā ʻaoʻao. ʻO ka maka mua e uhi i nā maka ʻelua, aia i ka hope ma hope o ke kaʻe o ke kino. Ke kino a me nā pua kekahi liʻiliʻi nā pua-spek. He lei hina ka ʻaoʻao o ka kino.
Eia nō naʻe, ʻaʻole hiki ke ʻike ʻia nā kiʻi o kēia mango i loko o nā ʻike ʻike, no laila, eia kahi kiʻi kiʻi i hana e like me ka wehewehe.
ʻAʻole maopopo i ke ʻano o ke ola o kēia mau poʻo. E like me nā kalaka a pau ʻo Cephaloscyllium, hiki iā lākou ke hoʻoulu i ka wai a huehue inā he pōʻino lākou, hoʻopiʻi i ke kino i loko o kahi crevice a ʻaʻole e ʻae ʻia e neʻe ʻia mai kahi pā. Eia kekahi, ʻo ka ʻike ʻana i kahi ʻōpū palu e hoʻowalewale i nā ʻenemi e hiki mai ana.
He mau nāhelehele i lalo ʻole, nā kumu kūpono o ka meaʻai o nā invertebrates haʻahaʻa liʻiliʻi - crustaceans, mollusks, juveniles of stingrays, sharks a me nā iʻa bony.
ʻO kā Kahu Ukiuki nui e hoʻohiki ana i ka hua. Hoʻokomo ka wahine i ʻelua hua hua i ka manawa, kahi i hoʻopili ʻia i loko o kahi kapake i loko o ke ʻano o kahi ʻano kīwī me ka antennae i nā kihi no ka hoʻopili ʻana i ka substrate.
E like me nā ʻelele āpau o nā poʻo nui, ke kumu kūʻai o ka Shark Cook ʻaʻole waiwai waiwai. E hoʻopau ʻia kēia mau iʻa i ka lawaiʻa haʻahaʻa ma waena o North Australia a me Indonesia hikina. ʻAʻohe ʻike e pili ana i ka nui a me ka hoʻohana ʻana o kēia mau mea e ka hopu.
ʻAʻole i wehewehe ʻia ke kūlana ʻoluʻolu o nā ʻano.DD) ma muli o ka loaʻa ʻole o nā ikepili ma ka kūlana o ka heluna kanaka.
No ke kanaka ʻaʻole pōʻino.
Kēkohu Shark Cook
He ʻano liʻiliʻi a liʻiliʻi kēia i ʻike ʻia i nā kahe, i loaʻa i kāna ho'ākāka ma 2008.
ʻO ka Shark Cook ka wai e noho ana ma kahi kai ma kahi ʻāpana o ke Kai Arafura, aia ma nā wahi o nā Mokupuni o Tanimbar (Malay Archipelago, Indonesia) a me ʻArelika Nui. Hoʻopili kēia ʻano holoholona i ke ola ma nā wahi i lalo o ke kai me nā algae a i hui pū ʻia me ka lepo lalo, i kahi hohonu o 220-300 m.
ʻO Kuke Kahua Nui (Cephaloscyllium Cooki).
ʻO ka wehewehe ʻana i ka Shark Cooked
Kūpono ʻia nā Cook Shark nui i manaʻo ʻia i kekahi o nā ʻano ʻeke o lalo, ʻoiai ʻo ka lōʻihi ka palena ma kahi kanaka he 29.5 cm.
Kūpono ka nui o ko lākou kino, ākea ko lākou mau poʻo a hoʻopili ʻia i luna.
Noho ka Shark Cook wale nō i ke Kai Arafura (Indonesia) ma kahi hohonu o ka 220-300 m.
ʻO ka laulā o ke kalō he 10,5-12.2% o ka lōʻihi. ʻO nā puhaka kuki he nui i loaʻa i nā pūhaka ākea pākahi (e pili ana i 1 cm), nā kūleʻa o ka ihu i hiki ʻole i ka lōʻihi o kahi ʻano o kēia ʻano. ʻEkolu āpau a vertex nā niho āpau, i kēlā me kēia iʻa. Eia kekahi, ma ka ʻūhā o luna, ʻike ʻia nā niho ʻoiai ua paʻa ka waha o ka manō.
He liʻiliʻi nā loina pectoral, me nā ʻōlelo aʻoaʻo. ʻOi aku ka liʻiliʻi o ka hope o ka hope o ka hope dorsal ma mua o ka anterior. ʻO nā ʻōlelo aʻo o nā dorsal fins.
ʻO ka fin dalal a me ka posterior dorsal like like me ke ʻano, akā ʻoi ka nui i mua o ka lua. ʻO kahi hiʻohiʻona hiʻohiʻona ma waena o ka wahine a me ke kāne, ʻo ka heleʻana o nā pterigopodia lua o ka lua (genital) ma nā pile pelvic. Ma ka moni caudal aia kahi ʻano lula o ka ventral like a like me ka pennant.
ʻO ka hiʻohiʻona hiʻona o ka Cook Shark he 6 pōuliʻu blurry mau maka ma hope o 2 a ma 2 o kahi huelo.
Lā uhi ʻia ka ʻili i ka pākuʻi placoid. Loaʻa i ke kino ka waihoʻoluʻu hina-poloka, nā wahi pōkoleʻeleʻele e ʻike ʻia nā ʻāpana a i hope. Hoʻonikani ʻia nā maka ʻelua i kahi hiʻona i mua o ka maka, ʻelua mau wahi ʻelua ma ka huelo. Hoʻopili i nā wahi ākea ākea, ma ke kino a me nā pupu he mau wahi liʻiliʻi liʻiliʻi o nā kala ʻeleʻele. He hina hina ka Abdomen.

ʻO ka papa ʻai o ka māka nui a Cook Shark ka mea i loko o ka wai hoʻowalewale i loko o ka wai: mollusks, young stingrays, crustaceans, etc.
Ua wehewehe mua kēia ʻano o nā pōlio puaʻa i kahi ʻatikala CSIRO.
Mea Pono e pili ana i ka Shark Cook
Ma kēia manawa, ʻike liʻiliʻi mākou i kēia mau pēpē pēpē, akā, e like me nā mea pihi a pau o ka gen Cephaloscyllium, hiki iā lākou ke pale aku iā lākou iho ma ke komo ʻana i ka ʻōpū o ka ʻōpū a kau ʻana iā lākou iho i kahi kihi, e pale aku ai i nā ʻenemi i ʻole. Eia kekahi, me kēia ʻimi, hoʻonaninani ka shark i nā mea hoʻopiʻi inā he pōpilikia.
E like me nā wīwī āpau, hoʻonui ka puhaka i ka ʻōpū i ka ʻōpū inā he pōpilikia.
E like me ka mea i hōʻike ʻia ma luna, ʻike liʻiliʻi mākou e pili ana i nā ʻakaʻaka ʻo Cook. I kēia hihia, ʻaʻole i hoʻokō ka poʻe ʻepekema i ka nui o ko lākou heluna kanaka. ʻAʻole kēia loea i ka waiwai o ka hana a ʻaʻole ia he pilikia i ke kanaka.

Kahi ʻia ka poʻo make nui i manaʻo ʻia e hoʻopau ʻia i ka ʻaoʻao hema ma ke komohana o ka holo ʻana o ke Komohana. Hiki ke loaʻa nā hakahaka o kēia ʻano i nā wai wale nō e pili ana i ʻAmelika Hema a me Mozambique. ʻAʻole nō i hōʻoia ʻia ka ʻike e pili ana i ka huki ʻana o ka poʻe poʻo nui i hopu ʻia ma waho o kēia pākahi a ʻaʻole i hōʻoia ʻia ka pili ʻana me ka pupule ʻauhau. ʻ suggestlelo nā kānaka ʻepekema ʻo ka poʻe i lawe i ke kahakai ʻo Vietnam a i loko o ke awāwa ʻo Aden, nona kekahi o nā ʻano hiʻoniʻo nui.
Hoʻaiho
Ua loaʻa iā lākou ma nā papa kuʻuna i luna, a ma ka papa ʻāina. Loaʻa kahi ʻokoʻa o ka hohonu makemake e hilinaʻi i ka nui o nā kanaka. ʻO nā ʻaka kūlohelohe, a hiki i 75 cm ka lōʻihi, e noho ana ma kahi hohonu o 40 a 440 mika, aʻo nā pākeke e makemake i nā wai hohonu (mai 440 a 600 mau mika).
ʻAno lawehala
ʻO nā hiu nui pōkole nui i hele i ka lōlō. Pakele kēia mau iʻa i ka ʻenemi e ka ʻauʻau ʻana i loko o nā pihi liʻiliʻi a hoʻoili i ko lākou kino i loko o lākou, ʻaʻole e ʻae i ka poʻe prediter e hopu iā lākou a hoʻihoʻi ʻole iā lākou mai ko lākou mau pāho. Ma ka like like, ka me ka wai o ka wai a me ka lewa, a me nā māka nui i hoʻonui ʻia ke koikoi ʻana no ke koena ma mua o ka wai.
ʻAno hānau
Ua ʻike ʻia kahi liʻiliʻi e pili ana i ka hoʻoulu ʻia ʻana o kēia mau ʻano pōpoki. Nāʻaʻaʻai Oviparous. Pālua ka wahine i nā hua ma nā pālua. Hoʻokomo ʻia kēlā me kēia hua mākaʻi me ka pūniki olakino lōʻihi, kahi i hoʻopili ʻia ai ua hua lā i ka lepo, algae a i ʻole invertebrates. Hoʻoulu ka hua hua ma nā hohonu hohonu (450-600 mika), kahi e noho mau ai nā pākeke.
He pono i ka poʻe
ʻAʻole ka inoa o nā hiu keu piha i kapa ʻia i nā ʻenehana a me nā waiwai ʻē aʻe. Hiki iā lākou ke hoʻoweliweli i ka poʻe lawe kīʻaha ma ke kīnā ʻana i kā lākou mauhe, akā, ka mea nui lākou hōʻino ʻoleʻino hoʻi i kānaka nā iʻa. ʻO ka ʻili o nā poki uluhua nui e ulia ana a hiki ke hoʻohana i ka nohona o kēlā me kēia lā.
Ke kūlana palekana
Ma muli o ka manaʻo ʻole e hana ʻino ʻole ka lawaiʻa i ka poʻe nui o ka hiwa nui i piʻi. Eia nō naʻe, ʻo ka liʻiliʻi o ka hana hōʻemi, ka liʻiliʻi o ka nohona a me ka hoʻonui i nā wahi lawaiʻa e pili i ka hopohopo i ka wā e hiki mai ana. I ka makahiki 2004, ua unuhi ka International Union for Conservation of Nature i nā ʻano i ke kūlana o "LC" - kumu no ka minamina loa. ʻAʻole hana i nā hana e mālama ai a ʻike i ka nui o ka lehulehu.
