He aha ke ʻano o nā manō keʻokeʻo nui?
ʻO ka manō keʻokeʻo nui kekahi o nā manō maoli. No ka mea, loaʻa iā ia ke ʻano maʻamau o ka manō: He ʻano torpedo ke kino, e lilo ia i mea ʻauʻau maikaʻi loa. He conical ka ihu a kuhikuhi. ʻO ke ʻano o ka ʻūhā ʻūhā, ka ʻūhā hope triangular, a me ka pectoral fins lōʻihi, ʻeleʻele ma ka ʻaoʻao. He keʻokeʻo ka ʻōpū, ʻulaʻula ke kua a ʻeleʻele hina.
Ma ka awelika, ʻo ka manō keʻokeʻo nui he 4.5 a 6.5 mika ka lōʻihi, ʻo kekahi a hiki i ʻehiku mika. ʻO ke kaumaha o nā mea liʻiliʻi he 700 kilokani, ʻo ka nui loa a hiki i 2000 kilokani. He ākea a poepoe iki ka waha, he huinakolu na niho. ʻO nā maka nui a me nā ʻāpana gill nui ke kuʻi.
Ma hea kahi e noho ai nā manō keʻokeʻo nui?
Loaʻa ka manō keʻokeʻo nui ma kahi kokoke i nā kai a pau, ʻoi aku hoʻi ma nā wahi mahana. Eia nō naʻe, ʻike ʻia ia ma nā kai subtropical a me nā kai ʻoluʻolu, kahi e loaʻa pinepine ai i ka hoʻoilo. He mea maʻamau ka ʻike ʻana ma waho o nā kapakai o ʻApelika Hema, Australia, New Zealand, a me Kaleponi. ʻO ka manō keʻokeʻo nui e hahai i nā wai pāpaʻu kokoke i kahakai kahi e noho ai nā sila he nui a me nā liona kai. A i ʻole, noho mau ʻo ia ma luna o nā papa ʻāina a ma ko lākou mau pali. ʻO ia nā wahi o ke kai kahi e hāʻule ai nā kihi o nā ʻāina i ke kai hohonu.
Holo pololei ka manō keʻokeʻo nui ma ka ʻili wai a ma ka hohonu a hiki i ka 1300 mika. I kekahi manawa hele lōʻihi loa ʻo ia.
ʻEhia makahiki o nā manō keʻokeʻo nui?
ʻAʻole maopopo i ka makahiki e hiki ai i nā manō keʻokeʻo nui. Eia nō naʻe, manaʻo ka poʻe noiʻi hiki iā lākou ke ʻano like me ke kanaka. Hiki ke hoʻoholo ʻia ka makahiki o ka manō me ka nui o kona kino: ʻo ka manō keʻokeʻo nui ʻelima a ʻeono mika ka lōʻihi ma kahi o 21 a 23 mau makahiki.

Pehea ka noho ʻana o nā manō keʻokeʻo nui?
ʻO ka manō keʻokeʻo nui he mea ʻaihue maikaʻi. No ka mea, he kino kūikawā kona i kona ihu: ka mea i kapa ʻia ʻo Lorenzini ampoules. ʻO kēia nā puka i hoʻopiha ʻia me kahi mea gelatinous. Me kēia mau mea, hiki iā ia ke ʻike i nā māla electromagnetic o kāna mea pio mai kahi mamao loa. Ua ʻoi aku ka maikaʻi o ka ulu ʻana o ka maka a me ka ihu ma mua o nā manō ʻē aʻe. No ka laʻana, hiki iā ia ke ʻike i nā kala a ʻike i nā ʻala liʻiliʻi loa o ka wai.
Eia kekahi, hāʻawi kahi pūnaewele kūikawā o nā kīʻaha koko i nā maka a me ka ihu i hiki iā lākou ke hana wikiwiki. ʻO ke kahe koko maikaʻi ʻo ia ke kumu i piʻi ai ka mahana o ke kino o ka manō keʻokeʻo nui a ʻaʻole maoli ke koko anu a hilinaʻi i ka mahana o ke kaiapuni.
ʻO ka mahana kino o ka manō keʻokeʻo nui he 10 a 15 degere Celsius ke kiʻekiʻe ma mua o ka wela o ka wai. Ma kekahi ʻaoʻao, hiki iā ia ke ʻauʻau wikiwiki a, ma kekahi ʻaoʻao, hiki iā ia ke noho ma ke kai anuanu. Aia nā ʻano like ʻole i nā manō nui ʻē aʻe a me nā tuna nui a i ʻole ka iʻa pahi.
A hiki i kēia mau lā, ua manaʻo ʻia ʻo ka manō keʻokeʻo nui he loner loa. Ua ʻike ʻia i kēia manawa he mau holoholona kaiapuni lākou a hana pinepine i nā hui liʻiliʻi. ʻOiai he nui ka poʻe e makaʻu nui i ka manō keʻokeʻo nui ma muli o nā hōʻike hoʻonui.
ʻOi aku ka nui o nā manō i pepehi ʻia e ke kanaka ma mua o ka make ʻana o ke kanaka e nā manō nui. ʻO ka mea nui, ʻaʻole ʻo ke kanaka i loko o ka papahana pio a ka manō keʻokeʻo nui. Akā, paʻakikī ka manō i nā leo a me ka hoihoi.
Ke neʻe kekahi mea i loko o ka wai, ʻauʻau ka manō i kēlā kumu o ka walaʻau. ʻO ia ke kumu e makemake ai lākou e "hoʻāʻo" i kahi holoholona pio - hiki ke lilo i kanaka - me ka nahu hoʻāʻo. Eia nō naʻe, ʻo ka nahu hoʻokahi e hōʻeha nui i ke kanaka a make pinepine.
ʻO nā hoaaloha a me nā ʻenemi o ka manō keʻokeʻo nui
ʻOiai ʻo ka manō keʻokeʻo nui he iʻa ʻaihue nui, ʻoi aku ka nui o nā mea ʻaihue i ke kai. ʻO nā koholā pepehi kanaka nui loa a me nā mea ʻaihue akamai i hiki ke lilo i mea hoʻoweliweli i nā manō keʻokeʻo nui. Eia nō naʻe, he mea kakaʻikahi ka poʻe kohola pepehi kanaka e pepehi i kahi manō keʻokeʻo nui. ʻO ke kanaka ʻenemi nui o ka manō keʻokeʻo nui. Huli ʻo ia i kēia iʻa kakaʻikahi, ʻoiai ua mālama ʻia.
Pehea e hānau ai nā manō keʻokeʻo nui?
ʻAʻole nui ka ʻike e pili ana i ka hana hou ʻana o nā manō keʻokeʻo nui. He viviparous lākou, ʻo ia hoʻi ka ulu ʻana o nā ʻōpio i loko o ka ʻōpū. Akā naʻe, ʻaʻole maopopo ka lōʻihi o ka hāpai ʻana o nā wahine. Manaʻo ka poʻe noiʻi he ʻumikūmālua mahina ka hānau ʻana o nā manō ʻōpio. A laila ua hiki i ka 150 kenimika ka lōʻihi.
ʻAʻole ʻike ʻia ka nui o nā keiki i ka wahine i ka manawa hoʻokahi. Ua ʻike mua ʻia nā holoholona me ʻeiwa ʻōpio. Aia kekahi ʻano ʻano ʻē i loko o ka manō keʻokeʻo nui: ʻo ia ka mea e hakakā ka ʻōpio kekahi i kekahi i loko o ka ʻōpū o ka makuahine.
