Introduction

The Yellow-faced Whip Snake is a slender and fast-moving snake, active during the day. It is common throughout most of Australia. It is often confused with the Eastern Brown Snake, and it is hard to observe closely, being alert and fleeing quickly when disturbed.


What do Yellow-faced Whip Snakes look like?

Identification

It is pale grey to brown in colour, with reddish colouring on the head, and sometimes on the tail as well. The belly is grey-green to yellowish. A dark comma-shaped streak runs from the eye to the corner of the mouth. The face is usually but not always yellowish, with a narrow, yellow-edged dark bar around the front of the snout from nostril to nostril. The average length is 80cm, with a maximum of 1m. Males are larger than females. It can be distinguished from the Eastern Brown by its facial markings, and smaller size.
