Off California, the Pacific angelshark is most common at a depth of 3–45 m (9.8–147.6 ft), but has been reported from as deep as 205 m (673 ft). [7] A number of genetically discrete subpopulations have been identified across the northern range of the Pacific angelshark.
The annual take of angel shark in 1977 was an estimated 147 kg. [11] By 1985, the annual take of angel shark on the central California coast had increased to more than 454 tonnes or an estimated 90,000 sharks. [11] The population declined dramatically and is now regulated. Angel sharks live very close to shore, resulting in high bycatch rates.
There are numerous species of sharks found in the Pacific Ocean; of these sharks, 36 [1] have habitat ranges throughout the coastlines and surrounding waters of California, as identified below. Identifications include common names; scientific names; the taxonomic rank, family; conservation statuses according to IUCN; and an image.
Other common names used for this species include angel, angel fiddle fish, angel puffy fish, angel ray, angelfish, escat jueu, fiddle fish, monk, and monkfish. [4] Stelbrink and colleagues (2010) conducted a phylogenetic study based on mitochondrial DNA , and found that the sister species of the angelshark is the sawback angelshark ( S. aculeata ).
In 1887, a researcher published the description of a Chilean angel shark, a small, ray-like shark that lives in shallow coastal waters, but it was incomplete and lacked accuracy, according to an ...

S. mapama, like all Squatina (angelsharks), has a wide and flat body resembling that of rays. [1]: 114 [2]Detail of nasal flaps of the fresh holotype. Its head length ranges from 16.5% to 17.5% of its total length (TL), and its head width is about 22.2% of TL, with the maximum head width just anterior of its gill opening.
