Species Squatina dumeril
Distinctive Features: Distinctive features of this shark
its flattened, skate-like body consisting of dorsally
and a terminal mouth
. The Atlantic angel
shark also possesses large
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).
Biome: Marine .
Little is known about this species. It is found seasonally in shallower
water. Off the eastern United
States it appears to move inshore
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 .
