Bites, snake
The only poisonous snake in the UK is the adder. Adders are only found from February- October as they hibernate during the winter. Their natural habitat (environment) is dry, open heathland.
Adders have a dark zigzag stripe down their back. They are quite short with large heads and their eyes are slanted rather than round. Males are usually grey with black markings; females are usually brown. Some adders are silver, yellow or green. They are not aggressive creatures and will only bite if they are disturbed.
The non-poisonous grass snake is a green-grey in colour. It may have black spots and yellow or orange markings in a ‘collar’ shape.
