Dogfish Shark
The spiny dogfish shark is the most abundant shark. This small shark is also known as the piked dogfish, skittledog, spotted dogfish, white-spotted dogfish, codshark, and thorndog. Its dorsal fin has spines that are mildly poisonous. More is known about it than any other species of shark; it is often studied in scientific laboratories. It is used extensively by people as food, fertilizer, hide, pet food, and liver oil.

The spiny dogfish shark is a small shark that is deep gray with some white spots; the belly is off-white. It had two dorsal fins, each preceded by a mildly poisonous spin. It has a short snout, large eyes and no anal fin.

Spiny dogfish sharks average 3-4 feet (0.9-1.2 m) long. The spiny dogfish shark stays in water that is between 45°F - 59°F (7°C - 15°C). It will venture into brackish waters. Dogfish are mostly bottom-dwellers, dwelling in depths from the surface down to 400 fathoms (2,400 feet).
