Physical Description

Species Squatina dumeril

Distinctive Features: Distinctive features of this shark include its flattened, skate-like body consisting of dorsally located eyes and a terminal mouth . The Atlantic angel shark also possesses large spiracles behind the eyes and expanded pectoral fins, both of which distinguish this shark from other species. This shark also has small dorsal fins of equal size located near the tail.

Dentition: This angel shark has three rows of twenty teeth on the top and eighteen on the bottom . The teeth are conical in shape with broad bases and smooth edges .

Denticles : The dermal denticles on the dorsal side are spaced evenly in corresponding rows along the surface. They have broad bases, are conical in shape, and slightly recurved. Around the eyes are larger denticles formed in clusters of 5 or 6.


The Atlantic angel shark ranges from a bluish-gray to an ashy-gray in color with a white underside. The head and portions of the fins have a reddish hue. There is a red spot located on both the throat and abdomen. These spots are arranged in an irregular fashion and may also be present over the entire dorsal side. This varied and seemingly sporadic coloring helps to camouflage this species when it is buried within the sea floor.


The adult Atlantic angel shark is relatively small, typically ranging from 3 to 4 feet (91-122 cm) in length , although occasionally reaching 6 feet (about 183 cm). Maturity is attained at 35-41in or (90-105 cm).


S. dumeril is considered a bottom dweller. It can generally be located buried in sand or mud at the ocean floor. In the northern areas of its distribution, this shark dwells in swallow water while found in deeper water (420 feet/ 128 meters) in its southern range .

Typically found in water with a depth of 0 to -2,278 meters (0 to -7,474 feet).[2]

Biome: Marine .

Ecology: Little is known about this species. It is found seasonally in shallower water. Off the eastern United States it appears to move inshore in the spring and summer, and disappears, apparently into deeper water in other seasons .

Maturity is probably reached around 90 to 107 cm TL . Reproductive mode is aplacental viviparous with only the left ovary functional. Pupping occurs in June or July with pups measuring 28 to 30 cm TL at birth. Litters contain up to 25 pups. Birth usually occurs at depth (~20 to 30 m ).

Eats small bottom fishes (flounders , skates and other bottom fishes), crustaceans and bivalves .

Feeds on a variety of bottom dwelling organisms . Mollusks and crustaceans occupy a large part of the shark's diet , as do bottom dwelling fishes such as flounders , skates , and stingrays.


The Atlantic angel shark is an ovoviviparous species with eggs that develop in enclosed capsules and hatch in the uteri. A litter usually consists of 16 pups , however litter sizes as large as 25 have been reported. Birthing usually occurs in the spring and summer months in depths of 60-90 feet (18-27 meters).



Larger species of fish and marine mammals are potential predators of the Atlantic angel shark .
