Wales's largest reptile - often seen
swimming across ponds in search of food
Habitat – It lives throughout Wales, especially
along the west coast and near water where it hunts frogs and fish
(it also eats small mammals and worms). It needs piles of rotting
vegetation or animal manure warmed by the sun as these are perfect
spots to lay eggs.
Appearance: It can grow to over 1m in length
and is our largest native snake. It is grey/green/olive in colour,
with varying amounts of black streaks on the flanks and a bright
yellow and black collar behind the head.
