The spiny dogfish is a small, well-known shark with a sharp spine in front of each of its two back fins. It lives in shallow and offshore waters in most parts of the world, especially cooler seas, and it is hunted heavily for food. Its spines are its main form of defence.1

Ihlala
Shallow and offshore waters in most parts of the world, especially temperate seas; the northern Pacific population is now a separate species, the Pacific spiny dogfish1
ULwandlekazi i-Atlantic, ULwandlekazi iPacific, ULwandlekazi i-India, Ulwandle iMediterranean, ULwandlekazi lwaseNingizimu, ULwandlekazi i-Arctic, I-Antarctica, Ulwandle i-North Sea
Ekhaya
It lives in shallow waters and further offshore, and is described as bottom-dwelling. It is commonly found at depths of about 50 to 149 m, and has been found deeper than 700 m. Commercial fishing brings it to fish markets, fish and chip shops and restaurants.1
Ubude

Indlela yokusibona

  • Two spines, one in front of each dorsal (back) fin.1
  • No anal fin on the underside.1
  • White spots along its back.1
  • Greyish brown on both sexes, with countershading (darker on top, paler underneath).1
  • Asymmetrical tail lobes, forming a heterocercal tail (the upper lobe is larger).1

Ivamise ukudidaniswa ne: Several shark species share the names dogfish, spurdog and piked dogfish. Spiny dogfish are told apart by having two spines, one in front of each dorsal fin, and no anal fin.1

Amandla obuthi

Ameva anobuthi

Ameva abukhali aphethe ubuthi. Ukusinyathela noma ukusibamba kubuhlungu.

Ubuthi baso benzani?

Its dorsal spines secrete a mild venom. The spines are driven into an attacker when the shark arches its back.1

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KubuhlunguKungaba buhlungu ngempela, kodwa cishe akukaze kube kubi kakhulu.

Senzani uma sesabile?

If it is caught, it arches its back to pierce its captor with the spines near its dorsal fins.1

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
