Kufotokozera
Maonekedwe a tsekwe laling'ono amafanana ndi whooper. Komabe, yomalizayi ndi yayikulu kukula. Mbali yapadera ya kachilomboka kakang'ono kuchokera kwa ena ndi mlomo wakuda pang'ono komanso wachikasu pang'ono. Achinyamata amasonyeza mlomo wonyezimira wonyezimira wokhala ndi mtundu wa pinki mbali imodzi ndi wokutira pamwamba.
Ikakhala pamadzi, kakhanda kakang'ono kamakanirira mwamphamvu mapiko ake kudera lakuthwa. Poyerekeza ndi whooper, khosi la nthumwi yocheperako ndilofupikitsa komanso lokulirapo, ndipo silimakhazikika kumapeto kwake. Mwa kuyika anthu awiriwa limodzi, kusiyana kwakukulu pakukula kwa thupi kumawoneka.
M'masamba achikulire, maso ndi miyendo ndizakuda kowala, mu anapiye, ndi khungu lachikasu. Oyimira achichepere ndi opepuka: pambali yakumbuyo, kumayendedwe kofiira, khungu la m'khosi ndi mbali zamutu ndizofiirira. Anthu amakhala ndi utoto woyera mchaka choyamba. Mutu, limodzi ndi khosi, umalandira utoto wake weniweni mchaka chachitatu cha moyo wawo. Khosi ndi gawo lamkati la khosi ndi loyera.
Pansi pa mulomo wa anapiye achichepere, mpaka m'maso, ndimowala bwino kwambiri pang'ono pang'ono. Nthenga zake zimakhala zobiriwira pafupi ndi mphuno, zotuwa pamwamba. Makona a mlomo ndi akuda. Kutalika kwa munthu wamkulu kumatha kufika 1.15 - 1.27 m. Mapiko ake amakhala pafupifupi 1.8 - 2.11 m. Kulemera, kutengera msinkhu komanso kugonana, kumatha kukhala pakati pa 3 mpaka 8 kg.
Chikhalidwe
