Dogfish

Dogfish

The most widely known species is Squaluas acanthias, called the spiny dogfish, spurdog, or skittle dog. It is abundant along northern Atlantic and Pacific coasts; a closely related, if not identical, form inhabits the southern half of the world. The spiny dogfish is gray, with white spots, and is about 60 to 120 cm (2 to 4 feet) long. Often found in dense schools, it preys on fishes and various invertebrates. It is often a nuisance, as it takes baits and damages fishing nets, but it is edible and also yields liver oil and is ground for fertilizer. Its dorsal fin spines are associated with small venom glands and can cause painful wounds.
