They have flattened bodies and wide [[pectoral fin]]s, which make them look similar to [[ray]]s. Twenty-three [[species]] are known. The [[genus]] is the only one in its [[family (biology)|family]], Squatinidae, and [[Order (biology)|order]] Squatiniformes. They are worldwide in [[temperate]] and [[tropical]] [[sea]]s. Most species are in shallow temperate or tropical seas, but one species is found in deeper water, down to 1,300 metres. <ref name=EoF>{{cite book |editor=Paxton J.R. & Eschmeyer W.N.|author= Stevens J. & Last P.R. |year=1998 |title=Encyclopedia of Fishes|url=https://archive.org/details/encyclopediaoffi00unse|publisher= Academic Press|location=San Diego|pages= [https://archive.org/details/encyclopediaoffi00unse/page/64 64]–65|isbn= 0-12-547665-5}}</ref> Angelsharks are specialised for a kind of [[predation]] which is unusual for sharks.
