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

Sida loo aqoonsado

  • 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

Inta badan lagu khaldaa: 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

Awoodda sunta

Qodxo sun leh

Qodxo fiiqan ayaa sunta sidda. Haddii aad ku tunto ama aad qabato wuu xanuunjiyaa.

Maxay samaysaa suntiisa (qaniin ama mudid)?

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

Intee buu dadka khatar ugu yahay?

Khatarta dadka: Xanuun badanAad buu u xanuunjin karaa, laakiin ku dhowaad weligiis khatar weyn ma aha.

Muxuu sameeyaa marka uu baqo?

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

Haddii qodxihiisu ku dhex galaan

Badbaado

  • Weligaa ha taaban, ha qaban, hana ku ciyaarin xayawaan duurjoog ah, xitaa mid yar, xitaa haddii uu u muuqdo inuu hurdo ama dhintay.
  • Meel u bannee. Haddii aad mid la kulanto, deg, tartiib dib ugu noqo oo u daa inuu jidkiisa maro.
  • Haddii qodxihiisu ku dhex galaan: deg, ha dhaqaaqin, wac lambarka gurmadka degdegga ah (112, 000, 911) ama si degdeg ah u tag isbitaalka. Xusuuso sida uu u egyahay, sawir ayaa caawiya.
