Overview
Dogfish sharks belong to the Squalidae family. They have a slender, elongated body with a pointed snout and two dorsal fins. Their skin is rough and covered in tiny denticles. Dogfish sharks are distinguished from other similar species by their two dorsal fins, which are both of similar size and shape, and their lack of an anal fin. They also have a distinctive "dog-like" face with a prominent snout and small eyes.

Migratory Patterns
Dogfish sharks, particularly spiny dogfish, exhibit seasonal migratory patterns. They typically move northward and into shallower waters during spring and summer, then southward and into deeper waters during fall and winter. Along the Atlantic coast of North America, they migrate from waters off New England and Atlantic Canada in the summer to areas off North Carolina and further south in the winter. In the eastern Pacific, they move from Alaska and British Columbia in the summer to waters off California in the winter.
