The colour varies from pale green to dark greenish/brown above and is creamy white below with variable dark mottling on the back or underside.

Adults may reach up to 17 cm long.

It may be green, bronze or brown, or a combination but is typically green on the upper lip. The belly is white with darker lines or spots. There may be some irregular spotting on the back.
