Pakusodza, ma dolphin amatha kugwiritsa ntchito njira zosiyanasiyana, kuphatikizapo zonse.

Kuti achite izi, nyama zanzeru zimachita izi:

tumizani ma scout kuti mukafune sukulu ya nsomba
zungulirani nsomba kumbali zonse, ndikudyetsa,
amayendetsa nsomba m'madzi osaya, kenako nkugwira ndikudya komweko.

Adalemba Buku Lofiyira

Ngakhale kuti dolphin wokhala ndi nkhope yoyera sanagulitsidwe pamlingo waukulu, M'mayiko ena monga ku Norway, Islands Islands, Greenland, Iceland ndi Labrador, ma dolphin awa adagwidwa mwadongosolo kuti agwiritsidwe ntchito pamakampani ogulitsa zakudya. Mwambiri, kuchuluka padziko lapansi kwamtunduwu kuli m'malo okhazikika. Chiweto chonse chikuyembekezeredwa anthu 100,000, ndipo pakadali pano palibe zomwe angachite kuti achepetse. Monga ma cetaceans, ma dolphin oyang'ana nkhope oyera atha kuyanika, zomwe zimayambitsa sizinayambike. Kuphatikiza apo, milandu yokhudza kupha nyama mu maukonde asodzi idadziwika. Chimodzi mwazomwe zimawopsa kwambiri pamtunduwu ndi kuwonongeka kwa madzi ndi zinthu za organochlorine ndi zitsulo zolemera.

Ndizosangalatsa

Ma dolphin ndi amodzi mwa opanga kwambiri komanso nthawi yomweyo zachilengedwe padziko lapansi. Nyama izi sizimangothandiza achibale awo pamavuto, koma nthawi zambiri zimathandiza anthu. Amakankhira dolphin kufooka kuchokera pagulu lawo kupita pamadzi kuti apumule, kuyesera kuthandizira nyama zomwe zikuloweka mu maukonde asodzi, kupulumutsa miyoyo ya anthu omwe akusweka ndi ngalawa. Asayansi aku America aku St. Andrews University of Florida apeza kuti ma dolphin amasiyanitsa aliyense osati ndi mawu komanso dzina. Pakubadwa kwa mwana, mayiyo amapanga likhweru lina, lomwe limatchedwa dzina lake. Pambuyo pake, likhweru lotere limakhazikika, ndipo mamembala ena a paketi amatha kusewera. Pakadali pano, izi zatsimikiziridwa mwasayansi kwa ma dolphin a botolo.

Chithunzi: Ma dolphin oyera okhala ndi mutu

Asayansi atsimikizira kuti mitundu yonse ya ma dolphin imagwiritsa ntchito chilankhulo chamanja kuyankhulana. Imatha kukhala kudumpha kapena kutembenuka, kusuntha kwa mutu kapena zipsepse, kukokana kwachilendo kwa mchira, ndi zina zambiri.

Komanso nyama zanzeru zimatha kulankhulana pogwiritsa ntchito mawu apadera. Ofufuzawo awerengera mawu opitilira phokoso oposa 14,000 ofanana ndi nyimbo. Pali nthano zokhudzana ndi nyimbo za dolphin pamadzi a padziko lonse lapansi komanso nthano zachabe zomwe zimapangidwa.

Zothandizira kumva za dolphin zimatha kudziwa phokoso lokhala ndi 200,000 pamphindikati, pamene anthu azindikira 20,000 zokha.

Nyama zimasiyanitsa mawu amodzi kuchokera kuzinthu, kuti zimasiyanitsa mosavuta. Pogwiritsa ntchito ma radiation osiyanasiyana omwe akupanga, nyama zimatha kufalitsa uthenga wofunika kwa wina ndi mnzake pa mtunda wautali pansi pa madzi. Kuphatikiza pa nyimbo, anthu amatha kusindikiza, kudina, kusewera, kuyimba muluzi.

Ma dolphins amatha kuchenjeza abale awo za ngozi, afotokozere momwe sukulu yayikulu ya nsomba, amuna amalimbikitsira akazi kuti azikwatirana. Zambiri zofunikira komanso zofunikira zimafotokozedwa ndi anthu kuchokera mkati mwanyanja, pogwiritsa ntchito mphamvu zamadzi zopangira mphamvu.

Pali mitundu iwiri ya mawu omwe ma dolphin amapanga:
