Nā hiʻohiʻona a me nā wahi noho o ka sila
Sila holoholona i loaʻa i loko o ke kai e kahe ana i loko o ke Kai Arctic, mālama ia ma kahi kokoke i ke kahakai, akā hoʻolilo ka hapa nui o ka manawa i ka wai.
He mea maʻamau ke kāhea ʻana i nā lunamaka o nā hui o nā wepa eared a me nā sila maoli. I nā kūlana ʻelua, hoʻopau nā lālā o nā holoholona i nā palule me nā māiʻuʻu i hoʻomohala maikaʻi ʻia. Aia ka nui o ka māmele i ka pili ʻana i kekahi ʻano a me nā subspecies. Ma ka awelika, ʻokoʻa ka lōʻihi o ke kino mai 1 a 6 m, paona - mai 100 kg a i 3.5 tone.
Ua like ke kino lōkō me ka spindle i ke kinona, liʻiliʻi ke poʻo i mua, kahi ʻāʻī neʻe ʻole, he 26-36 mau niho ka holoholona.
ʻAʻohe nā auricle - ma kahi o lākou, aia nā pale ma ke poʻo e pale i nā pepeiao mai ke komo ʻana o ka wai, loaʻa nā valves like i nā puka ihu o nā māmela. Ma ka waha o ka ihu he nui nā wīwī lōʻihi - tactissa vibrissae.
Ke hele ma ka ʻāina, huki ʻia nā peʻa hope, maʻalahi ʻole a hiki ʻole ke lawelawe ma ke ʻano he kākoʻo. ʻO ka nui momona momona o ka holoholona makua hiki ke 25% o ka nui o ke kaumaha o ke kino.
Aia i ka laha, ʻokoʻa ka mānoanoa o ka lauoho, no laila, kai kai ʻelepani - nā sila, ka mea loaʻa ʻole iā ia, ʻoiai e kaena ana nā ʻano ʻē aʻe i ka hulu kulu.
Kūleʻa ke kala - mai ka ʻulaʻula a i ka wepa hina, mai ka papu a i ka onionio a sila i ʻike ʻia... ʻO kahi mea hoihoi ʻo ia hiki i nā sila ke uē, ʻoiai ʻaʻohe o lākou mau lacrimal glands. He huelo liʻiliʻi kā kekahi mau laha, ʻaʻole pili i ka neʻe ʻana ma ka ʻāina a ma ka wai.
Ke ʻano a me ka nohona o ka sila
Sila ma he kiʻi me he holoholona kikole a lohi naʻe ia, akā hiki ke hana ʻia kēlā ʻano manaʻo inā aia ia ma ka ʻāina, kahi e neʻe ai nā neʻe ʻana o ke kino mai kekahi ʻaoʻao ai kekahi ʻaoʻao.
Sila sila
Inā pono, hiki i ka māmala ke piʻi i nā wikiwiki a i 25 km / h i ka wai. I ka ʻōlelo o ka luʻu, he poʻokela nō hoʻi nā lunamaka o kekahi mau ʻano - hiki i ka hohonu o ka luʻu ʻana a hiki i ka 600 m.
Eia hou, hiki i kahi sila ke noho ma lalo o ka wai ma kahi o 10 mau minuke me ka ʻole o kahi lako oxygen, no ka mea aia he ʻeke ea ma ka ʻaoʻao ma lalo o ka ʻili, kahi e mālama ai ka holoholona i ka oxygen.
Keʻauʻau nei i ka ʻimi ʻana i nā meaʻai ma lalo o nā kaola hau nui, nā sila me ka dexterity e ʻike ai i nā pua i loko o lākou e hiki ai ke hoʻopiha hou i kēia waihona. I kēia kūlana kani ke sila, like me ke kaomi ʻana, kahi i manaʻo ʻia he ʻano eolocation.
E hoʻolohe i ka leo o nā sila
Ma lalo o ka wai, hiki i ke sila ke hana i nā kani ʻē aʻe pū kekahi. ʻO kahi laʻana, hoʻonui ka sila elepani i kāna ʻeke ihu e hana i kahi kani e like me ka halulu o kahi elepani ʻāina maʻamau. Kōkua kēia iā ia e kipaku aku i nā hoa paio a me nā ʻenemi.
ʻO nā lunamaka'āinana o nā ʻano sila āpau i ko lākou ola i ke kai. Koho ʻia lākou ma ka ʻāina i ka wā hoʻoheheʻe wale a no ka hānau hou ʻana.
He mea kupanaha ka hiamoe ʻana o nā holoholona i ka wai, ʻoi aku, hiki iā lākou ke hana ia i nā ala ʻelua: huli i kona kua, paʻa ke sila ma ka ʻaoʻao ma muli o ka momona o ka momona a neʻe lohi hoʻi o nā palaka, a i ʻole e hiamoe ana, lele wale ka holoholona i lalo o ka wai (mau mika ʻelua), ma hope o ka puka ʻana, he mau hanu a hou hou, e hana hou i kēia mau neʻe i loko o ka manawa holoʻokoʻa o ka hiamoe.
ʻOiai ke ʻano o ka neʻe, i loko o kēia mau hihia ʻelua e hiamoe nui nei ka holoholona. Noho nā poʻe hānau hou i nā hebedoma 2-3 mua wale nō ma ka ʻāina, a laila, ʻaʻole ʻike maoli i ka ʻauʻau ʻana, iho lākou i loko o ka wai e hoʻomaka i kahi ola kūʻokoʻa.
Hiki i ke sila ke hiamoe i loko o ka wai, ke kaʻa nei ma luna o kona kua
ʻEkolu mau kiko o ke kanaka makua ma nā ʻaoʻao, ka papa o ka momona ma kahi o ia mea i emi iho ma mua o ke koena o ke kino. Me ke kōkua o kēia mau wahi, hoʻopakele ʻia ka sila mai ka wela nui ʻana, e hāʻawi ana i ka wela nui ma o lākou lā.
ʻAʻohe o nā ʻōpio i kēia hiki. Hāʻawi lākou i ka wela i ke kino holoʻokoʻa, no laila, ke moe ka wepa ʻōpio ma ka hau no ka manawa lōʻihi me ka neʻe ʻole, kū kahi puddle nui ma lalo ona.
I kekahi manawa hiki ke make i kēia, ʻoiai ke hoʻoheheʻe nui ka hau i lalo o ke sila, ʻaʻole hiki ke hele i waho. I kēia hihia, ʻaʻole hiki i ka makuahine o ka pēpē ke kōkua iā ia.Nā sila Baikal noho i loko o nā kino paʻa o ka wai, kahi ʻano ʻole o kekahi ʻano ʻē aʻe.
ʻAi hānai
ʻO ka meaʻai nui no ka ʻohana sila ka iʻa. ʻAʻohe o nā makemake kikoʻī o ka holoholona - he aha ke ʻano iʻa e launa me ia i ka wā e ʻimi holoholona ai, e hopu ʻo ia i kēlā.
ʻOiai, e mālama ai i kahi nui nui, pono i ka holoholona e alualu i nā iʻa nui, keu hoʻi inā ʻike ʻia i ka nui. I nā wā ʻaʻole kokoke nā kula iʻa i nā kapa i ka nui i koi ʻia e ka sila, hiki i ka holoholona ke alualu i ka mea pio, e piʻi ana i nā kahawai.
No laila, pili o ka sila sila i ka hoʻomaka o ke kauwela, hānai ia i nā iʻa e iho i lalo i ke kai ma nā kahawai o nā kahawai, a laila hoʻololi i capelin, e ʻau i ke kahakai no ka lawaiʻa ʻana. ʻO Herring a me salemona nā mea make hou aʻe i kēlā me kēia makahiki.
ʻO ia, i ka wā mahana, ʻai ka holoholona i ka iʻa he nui, ka mea nāna e hoʻāʻo i kahakai no kekahi kumu a i ʻole kekahi, ʻoi aku ka paʻakikī o nā mea i ke kau anuanu.
Pono e neʻe aku nā ʻohana sila mai nā kahakai, e pili kokoke ana i ka ʻauheʻe ʻana o ka hau a ʻai i nā pollock, nā molluscs a me nā heʻe. ʻOiai, inā kū kekahi iʻa i ke ala o ke sila i ka wā e ʻimi ai, ʻaʻole e ʻau.
Hoʻohua a me ke ola o kahi sila
Nānā ʻole i nā laha, hoʻopuka nā sila i nā keiki i hoʻokahi manawa wale nō i ka makahiki. Hana ʻia kēia ma ka hopena o ke kauwela. Akoakoa nā mākamela i nā rookeries sila nui ma ka ʻili o ka hau (ka ʻāina nui a i ʻole pinepine, he lana hau e heʻe nui ana).
Hiki i kēlā me kēia rookery ke helu i mau tausani mau kānaka. ʻO ka hapa nui o nā kāne he monogamous, akā naʻe, ʻo ka sila elepani (ʻo kekahi o nā sila nui nui) he pilina polygamous.
Hana ʻia ka male ma Ianuali, a ma hope o ka hānau ʻana o ka makuahine he 9-11 mau mahina sila i ka pēpē... Hiki ke kaupaona kahi pēpē ma hope koke o ka hānau ʻana he 20 a i ʻole 30 kg me ka lōʻihi o ke kino o 1 mika.
Cubson sila pepeiao
ʻO ka mea mua, hānai ka makuahine i ka pēpē me ka waiū, he 1 a ʻelua paha mau nipples o kēlā me kēia wahine. Ma muli o ka hānai ʻana, loaʻa wikiwiki nā sila - i kēlā me kēia lā hiki iā lākou ke kaupaona a 4 kg. Palupalu ka hulu o nā pēpē a keʻokeʻo pinepine, akā naʻe sila keʻokeʻo loaʻa iā ia ke kala mau o ka wā e hiki mai ana i 2-3 mau wiki.
Ke hala ka manawa o ka hānai ʻana me ka waiū, ʻo ia hoʻi, ma hope o hoʻokahi mahina ma hope o ka hānau ʻana (kaukaʻi ʻia i nā ʻano, mai 5 a 30 mau lā), iho nā pēpē i ka wai a laila mālama i kā lākou meaʻai ponoʻī. Eia nō naʻe, i ka manawa mua ke aʻo wale nei lākou i ka ʻimi holoholona, no laila noho lākou mai ka lima a ka waha, me ka mālama wale i ka lako o ka momona i loaʻa me ka waiū o ka makuahine.
ʻOkoʻa ka hana a nā makuahine hānai o nā ʻano ʻokoʻa. No laila, nā sila pepeiao i ka hapanui e noho kokoke i ka rookery, a me nā wahine nā sila liraE like me nā ʻano ʻē aʻe, neʻe lākou mai kahakai no kahi mamao loa i ka ʻimi ʻana i nā iʻa nui.
Mākaukau kahi wahine ʻōpio e hoʻomau i ka genus i ka makahiki o 3 mau makahiki, hiki i nā kāne ke oʻo makua i nā makahiki 6 wale nō. Aia ke ola o kahi kanaka olakino i ka laha a me ka moekolohe. Ma ka awelika, hiki i nā wahine ke hōʻea i nā makahiki o 35, nā kāne - 25.
