Pelagic Stingray (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The pelagic stingray (Pteroplatytrygon violacea) is a species of stingray in the family Dasyatidae, and the sole member of its genus. It is characterized by the wedge-like shape of its pectoral fin disc, which is much wider than long, as well as by the pointed teeth in both sexes, whip-like tail with extremely long tail spine, and uniform violet to blue-green coloration. It generally reaches 59 cm (23 in) in width. The pelagic stingray has a worldwide distribution in waters warmer than 19 C (66 F), and migrates seasonally to spend the summer closer to the continental shelf and at higher latitudes.
