Physical 

The smooth dogfish, also known as the dusky smooth-hound, is a species of shark. Their bodies are grey-brown in color and fade to a lighter shade toward the belly. They have two dorsal (back) fins and a notched caudal (tail) fin. They have large, oval, catlike eyes. Unlike other sharks, who have sharp teeth, smooth dogfish have flat teeth for grinding up shelled prey. Adults grow up to 5 ft (1.52 m).

Habitat

Smooth dogfish are seasonal migrants, so they only live in the Barnegat Bay for part of the year. Their range includes Massachusetts to Florida, the Gulf of Mexico, the Caribbean Sea, and also from Brazil to Argentina in South America. They travel in small schools, and reside from shallow waters down to the continental shelf.

Feeding 

Smooth dogfish are bottom feeders. They eat crustaceans (crabs, lobsters, shrimps), bony fish, squid, clams, gastropods, and worms.
