Roughtail stingray

Dasyatis centroura

Dasyatis centroura is a Stechrochenart and lives near the coast in independent populations in the northwestern, southwestern and eastern Atlantic and the Mediterranean.

Features

Dasyatis centroura has a diamond-shaped pectoral fin disc that is four times wider than long 1.2 to 1.3, with rather straight lateral lines that run right and left relatively pointed. It reaches a maximum wheel width of 2.6 meters and a length of up to 4 meters, with a maximum weight of 300 kg, females are larger than males. The top is dark brown to olive-brown, the lower raw white.

Way of life

The stingrays living in disjointed coastal areas of the Atlantic off the east coast of the U.S. between New England and the Gulf of Mexico, in the eastern Atlantic between the Bay of Biscay and Angola, including the Mediterranean Sea and the coastal waters of the Canary Islands, as well as isolated against South America between Venezuela and Argentina. He is a versatile predator that feeds on the available prey of each habitat. He usually hunts close to the ground, but also regularly in open water. Dasyatis centroura is ovoviviparous with litters of four to six pups. The larvae hatch in the womb, but remain in the rear part of the oviduct, which takes over the function of the uterus. The embryos are nourished by the yolk and zottenähnliche Sekretionskanäle by which they are supplied by the parent fish with nutrient solution. The young are born with skates wheel widths 34-37 cm in the northwestern and 8 to 13 cm in the Eastern Atlantic.
