Sharks in Alaska

Did you know?
Sharks live in the cold waters off Alaska.

Sharks (Class: Chondrichthys) are cartilagenous fish and can grow as large as the whale shark (41ft). The sharks in Alaska are not like their ferocious cousin the great white shark, but they do like to eat and are just as interesting. The three sharks that AFSC scientists study give a glimpse as to the diversity of sharks in the world. Salmon sharks, which looks like a mini-great white, are ferocious salmon eaters. Spiny dogfish are a more average sized shark (3ft to 5ft) and are commercially fished in some places. Sleeper sharks are flabby deep water sharks that suction feed from the bottom of the seafloor.
