The Pelagic Stingray (Pteroplatytrygon violacea) is a species of stingray  in the family Dasyatidae, and the sole member of its genus. trigone viola Pteroplatytrygon violacea

The adult specimens can reach 160 cm in length (including the tail) and 80 cm in width. It is characterized by a very tapered discoidal body with large pectoral fins. The eyes, unlike of the other stingrays, are not protruding.

Distributed in temperate and subtropical waters around the world; you discover it all over the Mediterranean Sea. It prefers a pelagic habitat, off the continental shelf and far from the seabed. trigone viola Pteroplatytrygon violacea

Much of the Mediterranean coast enjoys a hot-summer Mediterranean climate. However, most of its southeastern coast has a hot desert climate, and much of Spain’s eastern (Mediterranean) coast has a cold semi-arid climate. Although they are rare, tropical cyclone occasionally form in the Mediterranean Sea, typically in September–November.

Because of the short residence time of waters, the Mediterranean Sea is considered a hot-spot for climate change effects. Deep water temperatures have increased by 0.12 °C (0.22 °F) between 1959 and 1989. According to climate projections, the Mediterranean Sea could become warmer. The decrease in precipitation over the region could lead to more evaporation ultimately increasing the Mediterranean Sea salinity. Because of the changes in temperature and salinity, the Mediterranean Sea may become more stratified by the end of the 21st century, with notable consequences on water circulation and biogeochemistry.
