What do grass snakes look like?
The grass snake is the largest native snake, the males reaching up to 90cm (3 feet) in size. Mature females can be up to 150cm (5 feet) long, but it is rare for females to reach this size. Grass snakes are typically grey-green in colour, often with black spots and a yellow/cream/orange collar. Their colour varies according to distribution, and completely black or partial albino individuals sometimes occur. Black lines run down from their large golden eyes to their top lips. Their underside is usually white or pale yellow with checkering or blue-black and white markings. Their forked tongues are blue-black.
