ʻO ka sila crabeater (Lobodon carcinophaga) pili i ke kauoha Pinnipeds.
Hoʻokaʻina o ka sila crabeater
ʻIke ʻia ka sila crabeater ma kahakai a me ka hau o Antarctica. I nā mahina hoʻoilo, puka ia ma kahakai o ʻAmelika Hema, ʻAukekulelia, ʻApelika Hema, Tasmania, Nūhōlani, a kokoke i nā mokupuni like ʻole e pili ana iā Antarctica. I ka hoʻoilo, uhi ka pae ma kahi o 22 miliona mau mika kūlike. km
Kahi noho Crabeater
Noho nā sila Crabeater ma ka hau a kokoke i ka wai anuanu e hoʻopuni ana i ka ʻāina.
Nā hōʻailona kūwaho o kahi sila crabeater
ʻO nā sila Crabeater ma hope o ka molt kauwela he kala ʻeleʻele ʻeleʻele ma luna, a me ka malamalama ma lalo. Hiki ke ʻike ʻia nā māka ʻeleʻele ʻeleʻele ma ke kua, ʻeleʻele māmā ma nā ʻaoʻao. Aia nā poho i ke kino o luna. Hoʻololi mālie ke kapa i nā kala māmā i loko o ka makahiki a aneane keʻokeʻo loa i ke kauwela. No laila, kapa ʻia ka sila crabeater ʻo "ke keʻokeʻo Antarctic keʻokeʻo". He lōʻihi kona ihu a me kahi kino lahilahi e hoʻohālikelike ʻia i nā ʻano sila ʻē aʻe. ʻOi aku ka nui o nā wahine ma mua o nā kāne, me ka lōʻihi o ke kino o 216 cm a 241 cm. He lōʻihi ke kino o nā kāne mai 203 cm a 241 cm.
ʻO nā sila Crabeater he mau scars lōʻihi ma nā ʻaoʻao o ko lākou mau kino. ʻO ka mea nui paha, ua haʻalele ʻia lākou e ko lākou mau ʻenemi nui - nā leopadi kai.
ʻAʻole like nā niho o ka sila crabeater a ʻo "ka paʻakikī loa o nā mea ʻai ʻiʻo." Aia kekahi mau cusps ma kēlā me kēia niho me nā hakahaka ma waena o ka mea i ʻoki loa i loko o ka niho. ʻO nā cusps nui ma nā niho o luna a me lalo e pili pono. Ke pani ka waha o ka crabeater i kona waha, koe wale nā hakahaka ma waena o nā tubercles. ʻO kēlā nahu kahi ʻano sieve kahi e kānana ʻia ai ka krill - ka meaʻai nui.
ʻO ka sila hānai - crabeater
Hāpai nā sila Crabeater ma ka pahu hau a puni ʻo Antarctica ma ka Hemisphere Hema i ka pūnāwai, mai ʻOkakopa a Kekemapa. Hana ʻia ka male ma nā pā hau, ʻaʻole i ka wai. Hāpai ka wahine i ka bipi keiki no 11 mau mahina. Mai Kepakemapa, koho ʻo ia i kahi peʻa hau a laila hānau ʻo ia a hānai i hoʻokahi sila pēpē. Hui ke kāne i ka wahine i ka wahi i koho ʻia ma mua koke a ma hope paha o ka hānau ʻana. Pale ia i ka wahine a me ke keiki hānau hou mai nā ʻenemi a me nā kāne ʻē aʻe e komo hewa ana i ka panalāʻau i koho ʻia. Hānau ʻia nā sila ʻōpio ke kaupaona ʻia ma kahi o 20 kg a loaʻa wikiwiki i ka wā o ka hānai ʻana, loaʻa iā lākou ma kahi o 4.2 kg i kēlā me kēia lā. I kēia manawa, ʻaʻole haʻalele ka wahine i kāna keiki, inā neʻe ʻo ia, a laila e ukali koke ka cub iā ia.
Hoʻopau nā sila ʻōpio i ka hānai ʻana i ka waiū o ko lākou makuahine ma kahi o 3 mau pule o ko lākou makahiki. ʻAʻole maopopo i ka hana o nā hana physiological i ke kino iā lākou iho, akā e emi ana kāna hana waiū, a hoʻomaka ka sila ʻōpio e noho kaʻawale. Hana kolohe ke kāne makua i ka wahine i loko o ka wā lactation holoʻokoʻa. Pale aku ʻo ia iā ia iho ma ka nahu ʻana i kona ʻāʻī a me nā ʻaoʻao. Ma hope o ka hānai ʻana i nā keiki, lilo ka wahine i ka nui o ke kaumaha, aneane hapalua ka nui o kona kaumaha, no laila ʻaʻole hiki iā ia ke pale pono iā ia iho. Lawe ʻo ia i ka moekolohe ma hope koke iho o ka ukuhi ʻana.
Ua oʻo makua nā Crabeater ma waena o 3 a me 4 mau makahiki, a hānau nā wahine i nā keiki i ka makahiki 5, a ola a 25 mau makahiki.
ʻO ka hana sila Crabeater
ʻO nā sila Crabeater i kekahi manawa e hoʻokumu i nā concentrations nui a hiki i 1000 poʻo, akā, ma ke ʻano he rula, alualu liʻiliʻi lākou a i nā hui liʻiliʻi. Luʻu nui lākou i ka pō a hana i ka awelika o 143 luʻu i kēlā me kēia lā. I ka manawa i loko o ka wai, noho nā sila crabeater i loko o ka wai kokoke mau no 16 mau hola.
I ke kai kūloko, he holoholona agile a paʻakikī hoʻi kēia e ʻauʻau, luʻu, neʻe a hana i nā luʻu hoʻāʻo e ʻimi nei i ka meaʻai.
Lawe ka hapa nui o nā luʻu i ka wā huakaʻi, hala lākou i hoʻokahi minuke a hana ʻia i ka hohonu o 10 mika. Ke hānai ʻana, luʻu iki nā sila crabeater i kahi hohonu, a i 30 mau mika, inā lākou e hānai i ke ao.
Luu lākou i ka hohonu i ka pō ʻana o ka pō. Pili paha kēia i ka hāʻawi ʻana o krill. Hana hohonu ʻia nā luʻu hoʻāʻo e hoʻoholo i ka loaʻa o ka meaʻai. Hoʻohana nā sila Crabeater i nā lua hau i hana ʻia e nā sila ʻo Weddell no ka hanu ʻana. Kipaku pū lākou i nā sila Weddell ʻōpio mai kēia mau lua.
I ka hopena o ke kauwela, neʻe aku nā sila crabeater i ka ʻākau ke kū hau ka hau. ʻO kēia nā pinnipeds kelepona paʻalima, neʻe lākou i mau haneli mau kilomita. Ke make nā sila, mālama maikaʻi ʻia lākou, e like me "mummies" i ka hau ma kahakai o Antarctica. Eia nō naʻe, ʻo ka hapa nui o nā sila, huakaʻi huakaʻi lākou i ka ʻākau, a hōʻea i nā mokupuni moana, Australia, ʻAmelika Hema a ʻo ʻApelika Hema hoʻi.
ʻO nā sila Crabeater paha, nā pinniped wikiwiki loa e neʻe i ka ʻāina me ka wikiwiki a 25 km / h. Ke holo wikiwiki nei, hoʻokiʻekiʻe lākou i ko lākou poʻo kiʻekiʻe a hoʻoluliluli i ko lākou poʻo mai kēlā ʻaoʻao a kēia ʻaoʻao i ka lōkahi me nā neʻe o ke pelvis. E neʻe ʻokoʻa ke poʻo o ke alo i loko o ka hau, ʻoiai e noho nā lino hope ma ka honua a neʻe pū.
Mea ʻai silaʻi ʻai pāpaʻi
ʻAʻole pololei ka inoa crabeater sila, a ʻaʻohe hōʻike e ʻai ana kēia mau pinniped i nā pāpaʻi. ʻO ka meaʻai nui ka Antarctic krill a me nā invertebrates ʻē aʻe. ʻAʻau nā Crabeater i ka nui o ka krill me ko lākou waha e hāmama, omo i ka wai, a laila kānana i kā lākou meaʻai ma o kahi niho niho kūikawā. ʻO nā nānā ʻana i ke ola o nā sila crabeater i ka hoʻopaʻa pio ʻana ua hōʻike ʻia hiki iā lākou ke omo i ka iʻa i loko o ko lākou waha mai kahi mamao o 50 knm. ʻO ia ʻano pio ka nui o ka nui ma mua o krill, no laila, i ko lākou wahi maoli, hiki i nā sila crabeater ke omo i ka krill mai kahi mamao loa aku.
Makemake lākou e ʻai i nā iʻa liʻiliʻi, ma lalo o 12 cm, a ale iā ia holoʻokoʻa, ʻokoʻa ka ʻano o nā sila ʻē aʻe, kahi e haehae ai i kā lākou mea pio me ko lākou mau niho ma mua o ka ale ʻana. I ke kau hoʻoilo, ke loaʻa ka krill i loko o nā ana a me nā ana, loaʻa nā sila i ka crabeater i nā meaʻai i kēia mau wahi hiki ʻole ke kiʻi ʻia.
He manaʻo no ke kanaka
Noho nā sila Crabeater i nā wahi noho paʻakikī e hiki i nā kānaka, no laila ʻaʻole paʻakikī lākou e launa me nā poʻe. Maʻalahi ke hoʻomaʻamaʻa a hoʻomaʻamaʻa nā ʻōpio, no laila hopu ʻia lākou no nā zoo, nā aquarium wai a me ka circus, ma ke kahakai o ʻApelika Hema. Hoʻopilikia nā sila Crabeater i ka lawaiʻa kai ma ka ʻai ʻana i ka krct Antarctic, ʻoiai ʻo ia ka meaʻai nui no nā crabeater.
Ke kūlana mālama o ke sila crabeater
ʻO nā sila Crabeater nā ʻano pinniped lehulehu loa o ka honua, me kahi heluna kanaka o 15-40 miliona. Ma kahi o kahi e noho ai kahi mamao loa mai nā wahi ʻoihana, no laila, kū pololei nā pilikia o ka mālama ʻana i nā laha. Ua loaʻa nā kemikino hōʻino e like me DDT i nā crabeater i kekahi mau heluna. Eia hou, inā hoʻomau ka lawaiʻa no krill i ke kai Antarctic, a laila e ala aʻe ka pilikia o ka hānai ʻana i nā sila crabeater, ʻoiai hiki ke hoʻopau nui ʻia nā waihona mālama meaʻai. Hoʻonohonoho ʻia kēia ʻano ma ke ʻano ʻo Least Concern.
