Strophurus is a genus of lizards in the family Gekkonidae. All species of Strophurus are endemic to Australia, and are sometimes given the common names tail-squirters and spiny-tailed geckos.
The species of this genus are 80 to 130 mm (3.1 to 5.1 in) long. The scales of the body are generally small and round, sometimes interspersed with enlarged scales and soft spines.
All members of this genus have the unique defence, the ability to squirt a harmless, but smelly, fluid from their tails. This is used to deter birds while they are perching in shrubbery, being unusual in the family by exposing themselves during the day. As with other geckos, they are also nocturnal. Some members lack spines and enlarged scales, while another subgroup contains spines on the tail and other parts of the body. source
