GOLDEN CROWNED SNAKE Cacophis squamulosus (DUMERIL, BIBRON AND DUMERIL, 1854)
This distinctive snake is found from southern NSW, along the coast and near ranges to central coastal Queensland. This snake averages 50 cm although large females are known to exceed 70 cm, females being the larger sex.
The scalation is smooth with 15 mid body rows, 170-185 ventrals, divided anal and 30-52 divided subcaudals.
The Golden Crowned Snake is found in a variety of habitats, although when found in drier areas, it is usually found in proximity to water.
Specimens caught during the day are found under a variety of cover including ground litter, well embedded rocks, and even in hollow upright trees and bark on the sides of trees. At night this nocturnal species is commonly found crossing roads. The Golden Crowned Snake is a skink feeder and is often active on nights considered too cold for most other types of snake.
Golden Crowned Snakes are common in the inner suburbs of Sydney and Brisbane and are commonly brought into houses by domestic cats. These snakes will adopt a fierce raised striking posture when caught, but rarely actually bite.
Mating occurs in spring with an average of 6 large eggs being produced in summer. Hatchlings measure 16 cm.
