The common wonder gecko is active at night and is an excellent digger, excavating burrows down through the dry surface layers of sand and into moister subsurface layers. These burrows help the common wonder gecko to reduce water loss through its rather permeable skin during the day (2) (5).
The skin is particularly thin and delicate, and easily tears if the gecko is handled. The tail is also easily shed, as an escape strategy, but can be regenerated (2) (5). If threatened, the common wonder gecko displays a distinctive defence posture in which it stands on tiptoe, with the mouth open, the throat area expanded, the back arched and the tail writhing. If provoked further, it may squeak, dart forward and bite, before retreating to the burrow (2).
Little information is available on the diet or breeding behaviour of the common wonder gecko. In captivity, it may feed on insects such as beetles, crickets and grasshoppers, as well as snails, baby mice, and even its own hatchlings (2) (3). The female wonder gecko lays two hard-shelled eggs, which hatch after around 70 to 100 days (2) (4). The lifespan of the common wonder gecko in captivity may be up to 15 years or more (3).
