Chinyama dziko lalikulu: buluu zinsomba

Nyama yaikulu kwambiri m'nyanja dziko, buluu zinsomba kufika moona chachikulu - mpaka mamita 33 ndiponso kulemera zimphona izi ndi matani oposa 150. Yerekezerani yofanana akulemera 50 njovu African. Chifukwa moyo wake yogwira nyama chofunika tsiku lililonse zopatsa mphamvu miliyoni. Nangumiyu wa zinsomba baleen (mtundu zinsomba), zakudya zake lililonse - ndi nsomba yaing'ono, nkhanu, nyama, zomera ndi krill.

Kupeza kuti kuchuluka kwa chakudya mosavuta ngati mukudziwa kumene kwambiri wa nkhanu. Pa otchedwa "kudyetsa minda", pomwe ndende wamkulu zomera, n'zotheka kuona zinsomba angapo, koma anthu oposa 3 gulu, iwo zambiri osati zopereka.

Blue zinsomba ili paliponse nyanja dziko kuchokera kozizira ku Antarctic, pamene kusiyanitsa subtypes zingapo:

• kumpoto;
• kum'mwera;
• nyenyezi yaing'ono;
• Indian.

Woyamba mitundu iwiri amakonda madzi ozizira pa nyanja, ndi pygmy ndi Indian zopezeka m'nyanja otentha. Kutsogolera moyo yekha, nyama imeneyi yakhala mwini choyambirira njira zawo zoyankhulirana. Nthawi zina akulu m'magulu ang'onoang'ono, ngakhale ngakhale ngati yaing'ono, iwo okha.

Big Nangumiyu sikuti amakhala tcheru kununkhiza, ndi pafupifupi mosatsata pamaso, koma kuti wamaliza kulankhula kudzera "kuimba." Yolembetsera phokoso la amuna pa nyengo mating. nyimbo iyi ili ngati kulira loopsa angamvele pa mtunda wa 1600 Km. Akazi, kwambiri, nthawi zina akulankhula, koma ndi Bakuman ake. Malinga ndi asayansi, buluu zinsomba kusanthula phokoso, chifukwa njira yokha iwo kulankhula ndi dzikoli. Komanso dziwani luso ndi nzeru za nyama.

kuswana nyengo limapezeka pa zaka ziwiri. Pa kubala ana amatenga miyezi 10-11. Atabadwa mwana wamkazi amalidyetsa ndi mkaka miyezi 7-8, pa mapeto a nthawi ino, chinsomba wamng'ono akulemera pa 20 matani ndi kutalika mamita oposa 20. Panthawi imeneyi, khungu la mwana kale chidwi majeremusi m'madzi. kafukufuku sikumatha kupeza nambala yaikulu ya mkati ndi kunja majeremusi chinsomba. Ali kumeneko m'minda kudyetsa nyama wamkulu ali ndi diatoms, amene asayansi anayesedwa mitundu 31 ya nsomba pa chimodzi chokha. Khungu izi nyama ndi lachikasu wobiriwira mtundu, mollusks ambiri moyo mu malo omwewo, pa thupi nyama.

Kwa zaka zambiri, buluu zinsomba anaphedwa ndi munthu. Pakuti m'zigawo za whalebone, anthu mafuta ndi Taphunzira kuti ankasakidwa zimphona izi, kuchepetsa chiwerengero cha nthawi 100. Kumayambiriro kwa zaka za m'ma 20, nsomba kusalankhula zachititsa kuti kodi pano dziko alibe kuposa anthu 1500. Maulosi a asayansi zokhumudwitsa: view sangakhoze kupulumutsidwa ku anazimiririka ku nkhope ya Dziko Lapansi. Mu North Atlantic pa mphindi pali osapitirira 100 zinsomba wamkulu.

ikutha awo ukupitirira chifukwa kukhuthula m'nyanja, kuchucha mafuta ndi phukusi yogwira anthu m'chilengedwe. Kwambiri wosakwiya kukula zachilengedwe kwambiri kumabwezera mmbuyo ndi resumption a anthu, pamene zili mu zinthu yokumba n'zosatheka chifukwa cha kukula kwa nyama ndi.
