The White-crowned Snake is a small, slim snake up to 45 cm long. Its upper body is dark steely-grey to dark grey-brown and the belly is lighter grey. The black crown is encircled by a creamy-white band that is widest on the nape, extending around the sides of the head to enclose the snout. It is mainly nocturnal and reacts to disturbance by raising its head and upper body off the ground and making striking movements, but seldom attempts to bite.
Location and habitat
Distribution
Coastal and near-coastal areas from central eastern Queensland south to the vicinity of Coffs Harbour in north-east NSW. The western limit is the Legume area near the NSW-Queensland border; however, their stronghold appears to be the middle Clarence Valley.
Habitat and ecology
Favours low to mid-elevation dry eucalypt forest and woodland, particularly areas with a varied and well-developed litter layer, where their prey of small lizards may be more abundant. Also occasionally found in moist eucalypt forest and coastal heathland.
