Most species inhabit shallow temperate or tropical seas, but one species inhabits deeper water, down to 1,300 metres (4,300 ft).

There are two dorsal fins, no anal fin, the lower lobe of the caudal fin is longer than the upper lobe (Unusual for sharks). Most angel sharks grow to a length of 1.5 m (5 ft), with the Japanese angel shark, known to reach 2 m. Angel sharks possess extensible jaws that can rapidly snap upwards to capture prey, and have long, needle-like teeth. They bury themselves in sand or mud lying in wait for prey, which includes fish, crustaceans, and various types of mollusks. They are ovoviviparous, producing litters of up to 13 pups. |
