Species Guide
What to know about angel sharks
A clean field guide focused on habitat, identification, behavior, and conservation context without burying the useful parts.
Angel sharks belong to the genus Squatina and are the only living members of the family Squatinidae and order Squatiniformes. They have flattened bodies and broad pectoral fins that give them a strong resemblance to rays. Angel sharks occur worldwide in temperate and tropical seas, commonly inhabiting sandy seabeds around 150 m depth, with some species found as deep as 1,300 m. Most species are shallow-water inhabitants, while a few occupy deeper waters. They are ambush predators with a stationary, bottom-dwelling habit; this behaviour makes long-distance trans-oceanic migrations unlikely, although some large-scale coastal movements have been reported for species such as Squatina squatina.
Fishing pressure has resulted in significant population declines for many angel shark species; several are now classified as critically endangered by the IUCN.
Ambush predators with a stationary, bottom-dwelling habit; trans-ocean migrations are extremely unlikely, though some species show large-scale coastal movements.
Identification
How to identify angel sharks
The visual markers divers can use underwater, plus the species most likely to cause confusion.
Key identification markers
Habitat
Often found lying on sandy seabeds as bottom-dwelling ambush predators.
Depth range
Common around 150 m depth; some species occur down to about 1,300 m.
Common lookalikes
Rays
Flattened shape and broad fins make angel sharks superficially similar to rays.
Monkfish (Lophius)
The common name 'monkfish' is sometimes applied to angel sharks but also refers to Lophius species.

Conservation
What is happening with Angel Sharks
Status, pressure, and protection context grounded in cited sources rather than filler.
Fishing pressure has resulted in significant population declines for many angel shark species; several are now classified as critically endangered by the IUCN.
Main threats
Fishing pressure
Widespread fishing has driven significant population declines and contributed to many species being classified as critically endangered.
Protections and controls
IUCN listings
Many angel shark species are listed as critically endangered by the International Union for Conservation of Nature.
Responsible Encounters
How to dive with angel sharks
Conservation-minded guidance for divers who want the encounter without adding pressure.
Give angel shark space, avoid blocking the animal's path, and follow local site and operator rules for wildlife interactions with sharks.
