Javan rusa

The Javan rusa or Sunda sambar, Rusa timorensis, is a large deer native to Indonesia and Timor-Leste, with introduced populations in many parts of the Southern Hemisphere. Rusa is the Malay word for deer in general. Seven subspecies are recognised, from Timor, the Muna and Butung islands, Flores, Sulawesi, the Moluccas, Bali and Java. The animal is dark blackish brown with a gray forehead, a nearly black back and yellowish-brown underparts; males measure 142 to 185 centimetres in head and body length and weigh 152 to 160 kilograms, and females weigh about 74 kilograms. It natively occurs on Java, Bali and Timor, and the Dutch introduced it to New Guinea in the early 1900s. Its native population has fallen by about 10,000 animals in two decades, and it was declared protected under Indonesian law in 2018.
