Pelagic stingray, Purple trigon (Pteroplatytrygon violacea (Bonaparte, 1832)), is a fish of the family Dasyatidae, the only species of the genus Pteroplatytrygon.
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 the other stingrays, are not protruding. The mouth, located in the ventral position, has 25-34 rows of teeth on the upper jaw and 25-31 rows on the lower jaw. The teeth are formed by a pointed cusp and are suitable for cutting (unlike those of other breeds, suitable for crushing). The tail, long and similar to a whip, is endowed with one or two poisonous spines. The dorsal color varies from gray-violet to blue-green. The purple parsnip is very agile in swimming and feeds on small fishes, calamari, jellyfish and pelagic crustaceans, which pushes towards the mouth using pectoral fins.
It is an ovoviviparous species.
Distribution and habitat
Distributed in temperate and subtropical waters around the world. It prefers a pelagic habitat, exclusively off the continental shelf and far from the seabed.
