Angel SharkSquatina squatina
The angel shark can camoflage itself at the bottom of the ocean floor and when an unsuspecting squid or fish comes by, dinner is served. Most sharks must swim to breathe, but an angel shark has special muscles that pump water over its gills and through spiracles (holes) in its head. Angel sharks look like sting rays, but can bite with very sharp teeth.
