Squalus acanthias

This long, slender dogfish has a pointed snout, large eyes, and spines in front of its two dorsal fins. It is a brownish slate color, fading to a pale underbelly, with rows of white spots down its upper body that fade with age. These migratory, schooling sharks spend winters in deeper water where they possibly don’t eat much, and summer in coastal warm waters where they eat bony fish, smaller sharks, and many other sea animals. They rarely grow longer than 39 inches except in the cases of older females which have been caught up to 49 inches long.
