A short assessment of the behavior, habitat and habitat use of the sole member of its monotypic family, the Earless Monitor lizard Lanthanotus borneensis was undertaken for the first time. Field data of this important species were lacking for more than a century since its description in 1878. Nearly nothing is known about life history or even its natural habitat. The only previously known facts were taken from a few captive animals held in the early 60s and 70s of the last century. Metric data of size, weight, body temperature, and sex ratio of 19 individuals were examined. Natural food items were identified. The population structure of a subpopulation was estimated. A brief survey of the additional herpetofauna is given for the area.
