Relatively little is known about the biology of Lanza’s skink. Like other skinks, it is likely to be an active predator that feeds on insects and other small arthropods, and it may use chemical and visual signals to communicate (4).
In captivity, Lanza’s skink has been reported to hibernate between November and March or April (2). Courtship behaviour has not been observed in this species (2), but in many other skinks the male becomes aggressive during the breeding season and may perform displays to warn off rivals. During mating, male skinks usually hold the female in a ‘mating grip’ and often bite the female on the neck, limbs or body (4).
Lanza’s skink is viviparous (1) (2), giving birth to live young rather than laying eggs. Captive female Lanza’s skinks have been known to give birth to between five and eight young, from May to July. The newborn Lanza’s skinks measure around seven to eight centimetres in length and weigh only around one gram (2).
Captive Lanza’s skinks have been reported to first breed at four years old, and can live to at least six years of age (2).
