I-Black Sea ingenye yezilwandle ezisemqoka nezidumile emhlabeni. Unqenqema loLwandle i-Atlantic, oluphakathi kweMpumalanga Yurophu neNtshonalanga ye-Asia, seludume kakhulu. Igama libonisa uhlamvu olungenakulinganiswa kanye nezici eziningi ezingavamile. Imvelo engenawo umoya-mpilo wamanzi olwandle oLwandle Olumnyama, ngenxa yokuthi inqubo yokubola yenzeka kancane ezingxenyeni ezingezansi, nakho kwaveza amahemuhemu amabi, enezela ebhishi lezingulube udumo olubi lolwandle.
Ufezela olwandle olumnyama
NgoLwandle Olumnyama, amelwe ama-subspecies amabili. Umuntu uhlala ngasogwini, omncane ngosayizi, abadobi bavame ukumbamba ngezinduku zokudoba. Omunye uthathe isifiso sokujula futhi ufinyelela kumanani aqinile. IScorpena yinhlanzi enamaphiko amenyezelwe futhi avuthayo, ukukhula okuningi emzimbeni nomlomo omkhulu. Isici esibalulekile yizindlala ezinobuthi ezansi kwamaphiko nasezembozweni ze-gill, futhi ubuthi bunamandla, buthinta abantu abanezinto ezingezwani nomzimba, abanezinkinga nge-vascular and respiratory system.
Udrako wasolwandle
Ifihla ngasogwini lolwandle olumnyama, ihlasela abantu kusuka phansi kolwandle, lapho izifihla khona esihlabathini. Amehlo kuphela angaphezulu kwendawo engezansi, inhlanzi ibheke labo ababhukuda ngobuthi badle. Abantu bazama ukubamba ngezandla zabo, ngoba ngokubukeka udrako ubukeka njenge-gobies. Le nhlanzi idume kakhulu ngezinsipho zayo ezinobuthi ezingadala ukulimala kanzima kubantu. Ngenxa yemigogodla nobuthi obunamandla, le nhlanzi ihlukaniswa njengenye yobuthi obukhulu oLwandle Olumnyama.
Inkomo yasolwandle noma i-stargazer
Singamasentimitha angama-20-25 ubude, kodwa ezimweni ezehlukile sifinyelela kuma-40 cm futhi sinesisindo esingu-900 g. Inhloko enkulu nomzimba onesiqeshana esicishe sibe yindilinga, sicindezelwe ngasemsileni. Phezulu kwekhanda kunamehlo amancane anabafundi abavikelwe yisembozo esisobala, ukuvuleka okukhulu emlonyeni ngemigqa yamazinyo egobile ngaphakathi ukubamba izisulu. Ikhanda eligobile livikelwe ngamapuleti amathambo ama-4. Izinsipho ezimbili ezinamandla ezinobuthi ngemuva kwesifuba se-gill zidlise abadobi abaningi, abasusa ngokunganaki isazi sezinkanyezi ku-hook.
Ikati lasolwandle (i-stingray ejwayelekile)
Ama-stingray ahlala emanzini angajulile aze afike ku-50-60 m ukujula. Zikhetha olwandle olunesihlabathi, olunodaka, noma lwamatshe amancane, lapho zizungeza khona amatshe azungezwe inhlabathi ecacile. I-stalker itholakala ngamaqembu amancane noma eyodwa ngasikhathi, lapho isencane idla izakhamuzi ezincane eziphansi kolwandle, igubha ezinyaweni ezingezansi, igubha izidalwa ezindaweni zokukhosela, iqoqe izinhlanzi ezifile nezibolile. Njengoba ikhula futhi iba nkulu, iya kozingela izinhlanzi ezincane, inqabe ama-crustaceans kanye nezinambuzane ezingenamgogodla.
Isiphetho
Kunezinhlobo ezimbalwa zezinhlanzi oLwandle Olumnyama, ngoba amanzi aqukethe umoya-mpilo omncane. Lokhu kubi kwezokudoba, hhayi nje kuphela ukuhlukahluka kwezinto eziphilayo zasemanzini. Futhi phakathi kwezinhlobo ezingavamile eziguqulwe ukuze ziphile emanzini aphansi e-oxygen, kunezinhlobo eziningana zezinhlanzi ezinobuthi. Akunakwenzeka ukuthi umuntu omdala angafa ngemuva kokuthintana nabamele izilwane ezinoshevu ze-aqua, kepha futhi akumnandi kangako emiphumeleni elimazayo yama-neurotoxin wezinhlanzi zoLwandle Olumnyama.
