The '''Java stingaree''' ('''''Urolophus javanicus''''') is aan extinct [[species]] of [[Myliobatiformes|stingray]] in the [[family (biology)|family]] [[Urolophidae]], known only from a single female specimen {{convert|33|cm|in|abbr=on}} 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 EndangeredExtinction|Extinct]];<ref name="iucn status 31 December 2023" /> 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==

Line 23 ⟶ 20:

==Distribution and habitat==

The Java stingaree has only been found offin the [[Java Sea]], perhaps in the vicinity of Jakarta. Its exact range, and depth and [[habitat]] preferences, are unknown but probably very restricted.<ref name="iucn status 1631 NovemberDecember 20212023" />

==Description==

Line 29 ⟶ 26:

==Biology and ecology==

Very little is known of the natural history of the Java stingaree. It is presumably [[aplacental viviparous]] with a small litter size, as in other stingarees.<ref name="iucn status 1631 NovemberDecember 20212023" />

==Human interactions==

No new Java stingaree specimens have emerged since the first was discovered over 150 years ago, and it ishas fearednow tobeen beclassified as [[extinct]].<ref name="iucn status 1631 NovemberDecember 20212023" /> There is heavy fishing activity within its range, as well as [[habitat degradation]] from the proximity of major population centers. While it is possible that captured specimens have gone unrecognized, if this species still survivessurvived its population would almost certainly be gravely imperiled,imperilled; leadingthis has led to the [[International Union for Conservation of Nature]] (IUCN) to assessassessing it as [[CriticallyExtinct Endangered]]as of 22 March 2019.<ref name="iucn status 1631 NovemberDecember 20212023" />
