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

Ho e tseba jwang

  • 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

Hangata e ferekanngwa le: 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

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

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

Dintlha

1

Dogfish sharks have one of the longest pregnancies of any organism, lasting around 18 to 24 months.1

2

Spiny dogfish hunt in packs that can range up into the thousands.1

3

In England, dogfish are sold in fish and chip shops as 'huss', and used to be sold as 'rock salmon' until that term was outlawed.1

4

Spiny dogfish are popular dissection specimens in high schools and universities because they are easy to get and have small, cartilaginous skulls.1

5

Squalus acanthias fossils from the Miocene of Denmark and the Netherlands date from about 11 million years ago.1

6

Males are identified by a pair of modified pelvic fins called claspers, which they use to transfer sperm to the female.1

Ho senya ditshomo

Tshomo: All animals called dogfish or spurdog are the same species.

Nnete: These common names can apply to several species. Spiny dogfish are identified by their two spines, one in front of each dorsal fin, and by having no anal fin.1
