Mitundu m'madzi nkhumba ndi kufotokoza zomwe zili mu ukapolo

Kumva mawu akuti "porpoises", ambiri ali kunyumba makoswe furry ngati hamsters. Koma likukhalira, otchedwa oimira kuti Cetacea, akufanana ndi dolphin amene amakhala makamaka madzi amchere ambiri a m'nyanja ndi m'nyanja. Ena ntchito ngati chakudya anthu. Popeza porpoises mitundu yambiri ndi nyama pang'ono kutha, nsomba zawo ndikoletsedwa zisakuyenda bwino. Chifukwa cha kufanana chidwi ndi anamgumiwa, mabanja amenewa kawirikawiri osokonezeka osati anthu wamba komanso akatswiri zomera.

Monga nyama zina za m'madzi, porpoises ndi viviparous. zazikazi kudyetsa ana awo mkaka kwa ndithu nthawi yaitali. zakudya zawo Amakhala makamaka wa nsomba, koma nthawi zina monga nyama ndi nkhono.

Chiwerengero cha nyama izi catastrophically otsika. Malinga ndi asayansi, kuthengo alibe oposa 300 payekha. Pachifukwa ichi, kutchera misampha nyama koletsedwa, koma vuto limeneli si kuthandiza, chifukwa iwo bwanji chiwerengero cha chilengedwe osauka ndi kukhalapo kwa ambiri kwa nsombazo mu malo okhala. Iwo amakhala okha ndi Gulf of California, yomwe nthawi amadwala maukonde.

Izi mbira nkhumba si lalikulu kwambiri - mpaka masentimita 150 m'litali ndi makilogalamu 50 kulemera. Ali ndi thupi imvi ndi lalikulu wakuda "mfundo" kuzungulira maso. The mmunsi, monga anthu ambiri m'banja, mbandakucha pamwamba. Wochezeka nyama m'malo pang'onopang'ono, kupewa phokoso, anthu, ndi chilichonse chokhudzana ndi iwo.

Otchedwa chifukwa cha malo. Iye amakhala makamaka madzi a Ocean Pacific pafupi America South, ndipo nthawi zina amapezeka mu Atlantic. Kumasiyana ndi congeners ake mphamvu kwa nthawi yaitali kukhala mu chilengedwe madzi oyera. porpoises Argentine zambiri kusambira mu mitsinje pofunafuna nyama. Iwo akhoza kukhala kumeneko kwa masabata, akusuntha ndi panopa 50 Km.

Mosiyana ndi asuweni awo, zinsomba amakonda kukhala payekha. Ali ndi matupi mwachilungamo lalikulu lamphamvu (mpaka 180 masentimita m'litali). Mtundu wa thupi mdima imvi ndi kuunikiridwa sadzachitanso noticeable pansi. Chinyama chakudya chachikulu - nsomba ndi nyama.

Moyo mu ukapolo

Popeza kugwira mitundu yambiri ya m'madzi zimakhala ndikoletsedwa m'mikhalidwe yokumba ikuchitikira kamodzikamodzi. Kwenikweni, tikulankhula za m'chere zokhala m'malo owetera, malo kafukufuku, dolphin ndi malo nyanja. Ngakhale luntha la nyama sitinganene kuti ofooka amazigwiritsa Movutikira. Pachifukwa ichi, mu zoimira iwo amagwiritsidwa ntchito kawirikawiri.

The analibe ufulu kuyenda ndi porpoises yochepetsetsa danga zowawa zoipa kwambiri. Pa zili zoipa, nthaŵi zambiri amafuna kudwala ndipo akhoza kufa. Kudyetsa ziweto izi zikhoza kukhala zovuta. Ndithudi, zakudya wawo zikuphatikizapo nsomba. Porpoise - chilombo, ndi fastidious, ndi wosusuka.

ntchito anthu akhala zimawononga mphamvu pa anthu a mitundu onse porpoises. Akudwala masoka zachilengedwe, nsomba lamulo ndipo nthawizina kuphedwa, mwangozi kugwera maukonde.
