About this species

This rare and primitive monitor has a unique head shape without external ear openings. It is a nocturnal species and is rarely seen in the wild.

Enrichment & behavioral stimulation

Borneo Earless Monitor is aquatic or semi-aquatic โ€” enrichment combines a large water area, basking, and foraging.

  • Provide a large, clean water area for swimming and soaking.
  • Add a sturdy dry basking platform under heat and UV.
  • Include branches or ramps over the water for climbing and patrolling.
  • Scatter insects and offer food at different spots and times to extend activity.
  • Vary feeder types and sizes to keep feeding engaging.
  • Provide a secure dry hide out of the water.

Housing & Social Behavior

Solitary

Very sensitive species that requires precise solitary conditions for survival.

Housing guidance is general and based on species-typical behavior; always verify against current husbandry references and observe individual temperament.
