🦏Javan rhinoceros

Rhinoceros sondaicus Desmarest, 1822

Das Java-Nashorn (Rhinoceros sondaicus), auch Javanashorn oder Javanisches Nashorn geschrieben, ist eine in Asien beheimatete Nashornart mit nur einem Horn. Es ist nahe mit dem Panzernashorn (Rhinoceros unicornis) verwandt und der seltenste Vertreter der Nashörner und somit eines der seltensten Großsäugetiere. Die Art ist heute nur noch im Westen der Insel Java, im Ujung-Kulon-Nationalpark, mit etwa 50 Individuen anzutreffen. Ursprünglich war sie jedoch in weiten Teilen Südostasiens verbreitet und lebte teils sympatrisch mit den anderen asiatischen Nashornarten. Als Bewohner des tropischen Regenwaldes bevorzugt das Java-Nashorn weiche Pflanzennahrung, weiterhin lebt es überwiegend einzelgängerisch. Ein engagiertes Schutzprogramm soll helfen, das Java-Nashorn vor dem Aussterben zu bewahren.
