Java stingaree
The Java stingaree (Urolophus javanicus) is an extinct species of stingray in the family Urolophidae, known only from a single female specimen long caught off Jakarta, Indonesia. This species is characterized by an oval-shaped pectoral fin disc longer than wide, and a tail with a dorsal fin in front of the stinging spine and a caudal fin. It is brown above, with darker and lighter spots below, as well as a white speckled pattern along an extension of the dorsal. The International Union for Conservation of Nature has listed the Java stingaree as Extinct; as it has not been recorded since its discovery over 150 years ago, and its range is subject to heavy fishing pressure and habitat degradation.
