The members of the genus Rhinoceros are the one-horned rhinoceroses. The word "rhinoceros" is of Greek origin; "rhin" meaning "nose", and "ceros" meaning "horn". The genus contains two species, the Indian Rhinoceros (Rhinoceros unicornis) and the Javan Rhinoceros (Rhinoceros sondaicus). Although both members are endangered, the Javan Rhinoceros is one of the most endangered large mammals in the world with only 60 individuals surviving in Java (Indonesia). A fossil jawbone of an extinct species, Rhinoceros philippinensis, was found in the Philippines.
