The combination of electric blue tail with black body and three longitudinal yellow body stripes in a common pattern found in skinks, lacertids and other lizards around the world. It is possible that the stripes are intended to direct the eye of the predator towards the bright tail, thereby deflecting an attack away from the vulnerable lizard body. In New Guinea the blue-tailed skink exhibits sexual dichromatism, the females are brightly marked with blue tails while male blue-tailed skinks are usually light brown with indistinct stripes and a brown tail. These highly visible diurnal skinks are commonly observed on low vegetation and low on tree trunks, flicking their long tails.
