Squalus is a large genus of dogfish sharks, one of two genera in the family Squalidae. Commonly known as spurdogs, these sharks are characterized by smooth dorsal fin spines, teeth in upper and lower jaws similar in size, caudal peduncle with lateral keels; upper precaudal pit usually present, and caudal fin without subterminal notch.
The name comes from squalus, the Latin for shark; this word is the root for numerous words related to sharks such as squaline, and scientific names for sharks, such as the order Squaliformes.
