The angelsharks are a group of sharks in the genus Squatina in the family Squatinidae, which are unusual in having flattened bodies and broad pectoral fins that give them a strong resemblance to rays. Most species inhabit shallow temperate or tropical seas, but a few species inhabit deeper water, down to 1,300 m (4,300 ft). Angelsharks are sometimes called monkfish, although this name is also applied to members of the genus Lophius. They bury themselves in sand or mud lying in wait for prey, which includes fish, crustaceans and various types of molluscs. It usually resides in depths of 1–200 m and can be seen on the muddy or soft bottom substrate where they can easily blend in as they lie on the bottom. Although this shark is a bottom-dweller and appears harmless, it can inflict painful lacerations if provoked, due to its powerful jaws and sharp teeth. These sharks have a unique way of breathing compared to most other benthic fish. They do not pump out water from the oropharyngeal cavity like other fish. Instead, they use gill flaps located under their body to pump out water during respiration. Doing so also allows them to be more discreet and prevent detection. Credit: Wikipedia.
