Angular angelshark

The angular angelshark, Squatina guggenheim, is a flattened, ray-shaped shark of the angel shark family Squatinidae. It lives in the southwestern Atlantic off southern Brazil, Uruguay and Argentina, mostly on sandy or muddy sea floors in marine and brackish water at depths of roughly 4 to 360 metres. It feeds on bony fish, crustaceans and molluscs. Males and females both reach about 89 to 130 centimetres. Adult males carry a patch of small spines near the tips of the pectoral fins, which is thought to help them hold a female during mating, and the animals have 18 to 22 teeth in each jaw. The species is ovoviviparous: pregnancy lasts nine to twelve months, litters are usually three to nine pups, and only the left ovary is functional. Heavy fishing pressure on a bottom-dwelling shark has led the IUCN to list it as Endangered.
