The roughnose stingray, Pastinachus solocirostris, is a little-known species of stingray in the family Dasyatidae, generally found in shallow, estuarine waters associated with mangroves off Borneo, Sumatra, and possibly Java. Growing to 72 cm (28 in) across, this species has a rhomboid pectoral fin disc and a whip-like tail with a ventral fin fold. It is characterized by its pointed snout, which is covered by dermal denticles. Reproduction is aplacental viviparous, with females possibly bearing as few as one pup at a time. The International Union for Conservation of Nature (IUCN) has assessed the roughnose stingray as Endangered; it is threatened by overfishing and the destruction and degradation of its mangrove habitat.
