Description

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.
