Accepted Answer

The Sri Lankan Kangaroo Lizard (Otocryptis wiegmanni) is a striking endemic agamid found throughout lowland wet and intermediate rainforest floors. When startled or displaying territorial dominance, it raises its forelimbs off the ground and sprints bipedally on exceptionally long hind legs at remarkable speed, resembling a miniature kangaroo. Males possess a vibrant yellow or orange throat fan (gular fold) extended during rapid push-up displays to signal rival males across forest leaf litter.

Females lack the bright gular coloration, relying on cryptic brown patterning to remain invisible while laying eggs in shallow forest soil burrows.

They are diurnal insectivores, feeding actively on ants, beetles, and termites scurrying across decaying logs during warm morning hours.
