Adder or Viper Vipera berus

The adder is the only venomous native snake in Suffolk.  It has a noticeable dark zig-zag pattern on the back and the body colour varies between creamy yellowish, dark greens, greys and black for males, reddish brown for females.  Adders usually grow to about 60cm in length.  The adder has, unfairly, gained a bad reputation in some people's minds because it is venemous.  It is actually a timid animal and prefers to flee rather than bite.

Grass Snake Natrix natrix

The grass snake has an olive green body with some dark spots or flicks on the flanks and usually a distinct yellowish and black collar behind the head.  Grass snakes are Suffolk's largest snake growing to 80-100cm in length.  The grass snake lays eggs in compost, manure and heaps of rotting vegetation.  Batches of up to 40 eggs can be laid by one snake but many animals can lay eggs at a single site.

Slow-worm Anguis fragilis

The slow-worm ofteg gets called a snake but is actually a legless lizard.  If you examine a slow-worm you will notice it has eyelids and small scales on its belly, unlike snakes.  Slow-worms generally grow up to 30cm in length.  The males tend to be greyer and sometimes have blue flecks on their flanks.  The females are browner to black on their backs with a black or dark brown line.  The young are born between August and September and are a goldon/copper colour.
