The Atlantic stingray ( Hypanus sabinus ) is a species of stingray and lives off the northwestern coast of the Atlantic between Chesapeake Bay and Mexico .
features
Hypanus sabinus reaches a maximum total length of 61 cm and a weight of up to 4.9 kg, making it one of the smallest stingrays. It has a diamond-shaped pectoral fin disc that is a little wider than it is long, rounded on the sides and long and pointed towards the muzzle. The tail is long and whip-like and carries a venomous sting about a quarter of the width of the disc. The sting is renewed annually between June and October. The top is brown to yellow-brown, lighter on the edge, occasionally with a dark stripe along the back line. The underside is white to light gray.
Way of life
The ray lives in shallow water over sandy and muddy bottom on coasts, in river mouths and sometimes also in the freshwater area of rivers. There it feeds on mussels , cylinder roses , amphipods , crustaceans and polystyrene . The species is ovoviviparous with litters of one to four young animals born between July and August with a disc width of 10 to 13 cm.
Systematics
The ray species was described in 1824 by the French naturalist Charles-Alexandre Lesueur under the scientific name Trygon sabina , later assigned to the genus Dasyatis . When the Dasyatidae was revised in mid-2016 , the species was placed in the genus Hypanus .
