The common stingray can reach a maximum body length of 2.5 meters and a weight of up to 10 kilograms. As a rule, it remains well below one meter in length. It has a flattened body, typical of rays, in the shape of a diamond with a thin long tail. The back is marbled brown and dark, the underside is white. The stingray has a barbed poison sting on its tail (hence the species name pastinaca - because for the Romans the sting was similar to the parsnip root). Dorsal fins are absent.
distribution
The common stingray lives on the seabed in the eastern Atlantic from the south coast of Great Britain and the North Sea to South Africa and the Mediterranean Sea .
Way of life
Like the majority of the rays, the common stingray is a bottom-living fish, whereby it can be found near the coast up to 200 meters, mostly between 20 and 35 meters deep, on sandy and muddy bottoms. The crepuscular and nocturnal rays stay hidden in the sand during the day and feed mainly on invertebrates such as crustaceans , molluscs and echinoderms, as well as small fish.
The females are viviparous ( ovoviviparous ), the four to six embryos develop in a placenta-like area of the villi formed by the right fallopian tube and secreting nutrients. The gestation period is about four months.
