Spiny dogfish Squalus acanthias (also known as spurdog, piked dogfish and a number of other names) has five gill slits, all situated in front of the pectoral fins. This is according to Fishes of the Sea by John and Gillian Lythgoe (Blandford Press, 1991). The FAO FishBase (www.fishbase.org) is a good source of information on this and many other species of fish.
Sharks can and do live in the Black Sea. Leonard Compagno, an international authority on shark taxonomy, indicates in his 'Collins Field Guide to Sharks of the World' two species which occur in the Black Sea: the Angelshark (Squatina squatina) and the Thresher Shark (Alopias vulpinus). There is no doubt that a third species, the Spurdog or Piked Dogfish (Squalus acanthias), also occurs there, but it is strangely absent from the Black Sea on the distribution map. The author warns, however, that many distribution maps are likely incomplete, and that it is quite possible that many species have a wider distribution than illustrated.
