Origin and Evolution

The earless monitor is a species of lizard that originated in the Indonesian island of Borneo.

Over time, this adaptation allowed them to become more streamlined for swimming and hunting underwater prey.

Distribution and Habitat

Earless monitor lizards, also known as “orenge monitor,” are native to the Indonesian island of Borneo. They have been found in the Gunung Mulu National Park and the nearby limestone formations. These lizards inhabit forested areas and limestone karst ecosystems, often living in caves and crevices in rocky terrain.


The behavior of the earless monitor is typically shy and reclusive. They spend most of their time hiding and seeking shelter in rocks or burrows. If threatened or provoked, they may hiss or bite as a defensive response.


The diet of the earless monitor primarily consists of insects, such as crickets, mealworms, and roaches. They may also eat small vertebrates, including rodents and lizards, as well as occasional plant matter. A well-balanced diet is crucial for their overall health and longevity.


Earless monitor lizards are commonly bred in captivity. Breeding pairs require a large enclosure with a thermal gradient, UV lighting, and proper diet.
