Pacific angel shark

Did you know?

An angel shark spends its day buried in the sand, perfectly camouflaged by its gray, brown and black coloring. It lies there in ambush, waiting for small fishes to swim within gulping distance. When an unsuspecting fish comes near, the shark lunges upward, sucks the fish into its huge mouth and swallows it whole.

Conservation

Before 1978, angel sharks were usually thrown back when caught. But this changed dramatically when a Santa Barbara fish processor decided to promote the angel shark as a tasty morsel. After a slow start, the angel shark became so popular that the 366 pound (166 kg) catch in 1977 increased to 350 tons (318 metric tons) in 1984. As a result, the population of angel sharks rapidly decreased. Now there are limits on the minimum catchable size for angel sharks, and gillnet fishing is banned inshore of three miles (4.8 km).

Good news: Pacific angel shark populations are recovering.

Cool facts

• To get enough water flowing over their gills, some sharks—like hammerheads—must swim to breathe. However, most bottom-dwelling sharks, like angel sharks, have muscles that pump water over their gills and through spiracles (holes) in their heads. This allows bottom-dwelling sharks to snooze quietly on the bottom or wait in ambush for prey without moving.
• Even though bottom-dwelling sharks are usually gentle, picking up what appears to be a ray or a dead angel shark can be dangerous. The shark will probably raise its head and quickly inflict a painful wound with its sharp teeth.
