Uma ameva aso ekugwaza

Faka inxeba emanzini ashisayo, ashisa ngendlela umuntu angakwazi ukuyibekezelela ngaphandle kokusha (yihlole ngesandla sakho), imizuzu engama-30 kuya kwengama-90. Thola usizo lwezokwelapha, ikakhulukazi kuma-stonefish nama-stingray.

Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala

Hlala uphephile

Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
Uma ameva aso ekugwaza: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.

Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile

Amaqiniso

For its size, the horn shark has the strongest bite of any shark that has been measured.1

To pull prey loose, the shark pushes its head up with a downward stroke of its tail. No other shark has been seen doing this.1

Large horn sharks that eat many sea urchins can have purple-stained teeth and fin spines.1

A Pacific angelshark was filmed trying to swallow a juvenile horn shark, but spat it out because of the spines.1

Horn sharks have only 148 electroreceptors (ampullae of Lorenzini), far fewer than most sharks, which may have over 2,000. They rely mainly on smell to find food.1

A dropped tooth takes about 4 weeks to be replaced.1
