Java stingaree
The Java stingaree (''Urolophus javanicus'') is a 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. The International Union for Conservation of Nature has listed the Java stingaree as Critically Endangered; it has not been recorded since its discovery over 150 years ago, and its range is subject to heavy fishing pressure and habitat degradation.
==Taxonomy==
In July 1862, German zoologist Eduard von Martens purchased the sole known specimen of the Java stingaree at a fish market in Jakarta. He described it as ''Trygonoptera javanica'' in an 1864 volume of the scientific journal ''Monatsberichte der Akademie der Wissenschaft zu Berlin'' (''Monthly Report of the Academy of Sciences, Berlin''). Subsequent authors moved this species to the genus ''Urolophus''.
