The Javan tiger (Panthera tigris sondaica) is an endemic animal that lives on the island of Java, Indonesia, which was declared extinct in the mid-1970s. Its extinction was caused by several factors, such as hunting and conversion of land which is its natural habitat. In Indonesian society, especially Java, at that time, there was a belief that tigers were the incarnation of ancestral spirits who guarded and monitored the behavior of villagers.
