Ecology and habitat
The beaded gecko is a terrestrial (ground-dwelling) animal that can be found in a variety of dry desert habitats within mainland Australia from the savannah woodlands to spinifex-covered sandhills. During the day the gecko uses insects and spider holes for shelter before coming out at night to hunt in open areas. This swift-moving gecko covers large areas in search for food.Reproduction
The beaded gecko is oviparous, meaning it lays eggs rather than giving birth. Females are known to lay 2 eggs per clutch. Like most Australian reptiles, geckos have a breeding season which is from late September to December. Males have paired sex organs, each independent.Diet
Beaded geckos like most other small lizards feed mainly on insects. The jaw is surrounded with short fine teeth; however, prey is crushed by the gecko rather than chewed.Threats
Threats include loss of habitat, and feral predators like dogs, cats and foxes.Lucasium damaeum at the Australian Reptile Online Database. Last updated 2016-03-29 11:18:15.Retrieved from http://www.arod.com.au/arod/?species=Lucasium+damaeum on 4 June 2016.References
