identification
Elongated shark with a long snout, which gives the species its name. Like other dogfish, it has spines on the dorsal fins. On the same Uruguayan coast lives the catfish shark, Squalus megalops, which has a short, angular snout. Snout length is the main trait for telling the two apart.
