ano

Pehea ke ano o ka sila?

No ka ʻohana o nā sila a me ke ʻano o nā mea ʻai ʻai. ʻOi aku ka liʻiliʻi ma mua o nā sila ʻē aʻe. ʻO nā kāne ma ka awelika a hiki i 180 knm ka lōʻihi a me ke kaumaha 150 kg, nā wahine 140 cm a me 100 kg.

He poepoe ko lakou mau poo a he keokeo-hinahinahina ko lakou hulu. Loaʻa iā ia ke ʻano o nā kiko a me nā apo. Ma muli o ka ʻāina, hiki ke ʻokoʻa ke kala a me ke ʻano. Ma nā kapakai Kelemania, ʻeleʻele hina hina nā holoholona me nā kiko ʻeleʻele. I ko lākou ulu ʻana, ua hoʻololi maikaʻi ʻia nā sila i ke ola i loko o ka wai. Hoʻopili ʻia ko lākou kino, hoʻololi ʻia nā wāwae mua i ʻano like me ka ʻili, ʻo nā wāwae hope i nā ʻūhā caudal.

He mau wāwae ko lākou ma waena o ko lākou manamana wāwae. Ua emi ko lākou mau pepeiao i ʻike ʻia nā puka pepeiao ma ke poʻo. He māwae haiki ka puka ihu a hiki ke pani loa i ka luʻu ʻana. He mea maʻamau ka ʻumiʻumi me ka ʻumiʻumi lōʻihi.

Ma hea kahi e noho ai nā sila?

Māhele ʻia nā sila ma ka ʻāpana ʻākau. Loaʻa lākou ma ka ʻAkelanika a me ka Pākīpika. Ma Kelemānia, loaʻa nui lākou ma ke Kai Akau. Ma ka ʻaoʻao ʻē aʻe, ʻike pinepine ʻia lākou ma ke Kai Baltic, a laila ma nā kahakai o Denemaka a me nā mokupuni ʻo Suedena hema.

Noho nā sila ma nā kapa one a me nā kahakai. Noho lākou ma nā wahi pāpaʻu o ke kai. Eia nō naʻe, neʻe nā sila i kekahi manawa i loko o nā muliwai no ka manawa pōkole. Noho kekahi subspecies i loko o ka loko wai ma Kanada.

He aha nā ʻano o nā sila?

ʻElima mau subspecies o nā sila. Noho kēlā me kēia o lākou ma kahi ʻāpana like ʻole. E like me ka hōʻike ʻana o kona inoa, ua maʻamau ka sila ʻEulopa ma nā kahakai o ʻEulopa. Noho ka sila Kuril ma nā kahakai o Kamchatka a me ka ʻākau o Iapana a me nā mokupuni ʻo Kuril.

ʻO nā subspecies wale nō i loaʻa i ka wai maʻemaʻe ʻo ka Ungava seal. Noho ʻo ia ma kekahi mau loko ma ka moku ʻo Kanada ʻo Québec. Aia ka ʻehā o nā ʻano ʻano ma ke kahakai hikina, ʻo ka ʻelima ma ke kahakai komohana o ʻAmelika ʻĀkau.

Ehia makahiki o ka sila?

Hiki i nā sila ke ola 30 a 35 mau makahiki ma ka awelika. ʻOi aku ka lōʻihi o ka noho ʻana o nā wahine ma mua o nā kāne.

Pehea ke ola o ka sila?

Hiki i nā sila ke luʻu a hiki i 200 mika ka hohonu a ma nā hihia koʻikoʻi no 30 mau minuke. 'Ai'ē lākou i ka hiki ke ho'ololi kūikawā i ko lākou kino: He nui ka hemoglobin i kou koko. ʻO kēia ka puaʻa koko ʻulaʻula e mālama ai i ka oxygen i loko o ke kino. Eia kekahi, hoʻolohi ka puʻuwai i ka wā e hoʻokele ai, no laila e pau ka oxygen i nā sila.

I ka ʻauʻau ʻana, hoʻohana nā sila i kā lākou mau hiʻi hope no ka hoʻoulu ʻana. Hiki iā lākou ke piʻi i ka wikiwiki a hiki i 35 mau kilomita i kēlā me kēia hola. Hoʻohana nui ʻia nā ʻili mua no ka hoʻokele. Ma ka ʻāina, ma ka ʻaoʻao ʻē aʻe, hiki iā lākou ke neʻe wale me ke kolo ʻana ma luna o ka honua e like me ka enuhe me ka hoʻohana ʻana i ko lākou mau alo mua. ʻAʻole hoʻopilikia ka wai anuanu i nā sila:

ʻO kā lākou hulu me 50,000 mau lauoho no ke kenimika kūhāhā e hana i kahi papa insulating o ka ea a ma lalo o ka ʻili, aia kahi papa momona a hiki i ʻelima kenimika ka mānoanoa. ʻAe kēia i nā holoholona e hoʻomanawanui i ka mahana a hiki i -40° Celsius. Hiki i nā sila ke ʻike maopopo loa ma lalo o ka wai, akā pohihihi ko lākou ʻike ma ka ʻāina. Maikaʻi nō hoʻi ko lākou lohe ʻana, akā hiki ke honi ʻino.

ʻO ka hoʻololi hoihoi loa i ke ola i loko o ka wai, ʻo ia ko lākou ʻumi: ʻO kēia mau lauoho, i kapa ʻia ʻo "vibrissae", ua hui pū ʻia e nā aʻalolo 1500 - ma kahi o ʻumi mau manawa ʻoi aku ma mua o ka ʻumi o ka pōpoki. He antennae koʻikoʻi lākou: Me kēia lauoho, hiki i nā sila ke ʻike i nā neʻe liʻiliʻi loa i ka wai. ʻIke lākou i ka mea e ʻauʻau ana i loko o ka wai: No ka waiho ʻana o nā iʻa i nā ʻeleʻele maʻamau i loko o ka wai me kā lākou neʻe ʻana o ka hope, ʻike pono nā sila i ka mea pio i ko lākou wahi kokoke.

Me lākou, hiki iā ʻoe ke hoʻonohonoho pono iā ʻoe iho me ka wai ʻeleʻele. Hiki i nā sila makapō ke ʻimi maʻalahi i ko lākou ala i ka wai me kā lākou kōkua. Hiki i nā sila ke hiamoe i ka wai. Lana lākou i luna a i lalo i ka wai a hanu hou i luna o ka ʻili me ke ala ʻole. I loko o ke kai, ʻo lākou wale nō, ma ka ʻāina, ke hoʻomaha lākou ma nā kapa one, hui pū lākou. Eia nō naʻe, he mau hoʻopaʻapaʻa ma waena o nā kāne.

ʻO nā hoaaloha a me nā ʻenemi o ka sila

Ma waho aʻe o nā iʻa predatory nui e like me nā kohola pepehi kanaka, ʻo ke kanaka ka mea hoʻoweliweli nui loa i nā sila: ua ʻimi ʻia nā holoholona e nā kānaka no nā tausani makahiki. Hoʻohana ʻia ko lākou ʻiʻo i mea ʻai, a hoʻohana ʻia ko lākou hulu e hana i nā lole a me nā kāmaʻa. Ua pilikia pū lākou i ka haumia kanaka o ke kai.
