Nyanja Yakuda ndi imodzi mwanyanja zazikulu komanso zotchuka padziko lapansi. Mphepete mwa Nyanja ya Atlantic, yomwe ili pakati pa Eastern Europe ndi Western Asia, kwakhala kwachilendo kwanthawi yayitali. Dzinali likuwonetsa mawonekedwe osasangalatsa komanso zinthu zina zachilendo. Chikhalidwe chopanda oxygen chamadzi am'nyanja Yakuda, chifukwa choti kuwonongeka kumachitika pang'onopang'ono m'malo am'munsi, zidadzetsanso mphekesera zowopsa, kuwonjezera ku banki ya nkhumba kutchuka kwachisoni panyanja.
Chinkhanira chakuda
Mu Nyanja Yakuda, imayimilidwa ndi ma subspecies awiri. Wina amakhala kufupi ndi gombe, laling'ono, asodzi nthawi zambiri amamugwira ndi ndodo. Wina adatenga zokongola mpaka pansi ndikufika pamiyeso yolimba. Scorpena ndi nsomba yokhala ndi zipsepse zotulutsa mawu, zophuka zambiri pathupi ndi pakamwa kwambiri. Mbali yofunika ndi tiziwalo timene timatulutsa poizoni m'munsi mwa zipsepse ndi zokutira phala, ndipo poyizoni ndi wamphamvu, imakhudza anthu omwe ali ndi chifuwa, mavuto am'mitsempha komanso kupuma.
Chinjoka cha m'nyanja
Imabisala m'mbali mwa gombe la Black Sea, imazunza anthu kuchokera pansi pa nyanja, pomwe imadzibisa mumchenga. Ndi maso okha omwe ali pamwambapa, nsomba ikuyang'ana omwe amasambira ndikuyika poizoni ndikudya. Anthu amayesa kugwira ndi manja, chifukwa mawonekedwe chinjokacho chikuwoneka ngati gobies. Nsombazi ndizodziwika bwino chifukwa cha msana wake wakupha womwe ungavulaze kwambiri anthu. Chifukwa cha mitsempha ndi ululu wamphamvu, nsombazo zimawerengedwa kuti ndi imodzi mwazowopsa kwambiri ku Black Sea.
Ng'ombe yam'nyanja kapena nyenyezi
Ndi kutalika kwa 20-25 cm, koma nthawi zina kumafikira 40 cm ndikulemera magalamu 900. Mutu waukulu ndi thupi lokhala ndi gawo loyandikira mozungulira, lopanikizika kumchira. Pamwamba pamutu pali maso ang'onoang'ono okhala ndi ana otetezedwa ndi chivundikiro chowonekera, kutseguka kwakukulu pakamwa ndi mizere ya mano yopindidwira mkati kuti agwire ozunzidwawo. Mutu wokhotakhota umatetezedwa ndi mbale zinayi zamfupa. Mitsempha iwiri yamphamvu yakupha kumbuyo kwa mafinya yakhala ikudyetsa asodzi ambiri, omwe mosamala amachotsa wopendekayo pachikopa.
Nyama yam'madzi (wamba stingray)
Ma stingray amakhala m'madzi osaya mpaka 50-60 m kuya. Amakonda mchenga, matope, kapena matanthwe apansi, pomwe amayenda mozungulira matanthwe ozunguliridwa ndi nthaka yoyera. Mbalameyi imatha kupezeka m'magulu ang'onoang'ono kapena kamodzi, ikadali yaying'ono, imadya nyama zazing'ono zam'madzi pansi, imakumba pansi, imakumba nyama kuchokera kumisasa, imasonkhanitsa nsomba zakufa ndi zowola. Pamene akukula ndikukula, amapita kukasaka nsomba zazing'ono, amakana nkhanu ndi nyama zopanda mafupa.
Mapeto
Pali mitundu yochepa ya nsomba ku Black Sea, chifukwa madzi amakhala ndi mpweya wochepa. Izi ndizoyipa kwa asodzi, osati zamoyo zosiyanasiyana zam'madzi. Ndipo mwa mitundu yosawerengeka yomwe yazolowera kukhala m'madzi otsika a oxygen, pali mitundu yambiri ya nsomba zakupha. Sizingatheke kuti munthu wamwalira atamwalira atalumikizana ndi oimira nyama zakutchire zam'madzi, komanso osasangalala ndi kuwonongeka kwa ma neurotoxin a nsomba za ku Black Sea.
