Gray Ratsnake

Gray Ratsnake Identifying Features

The gray ratsnake is Canada’s longest snake species, growing to 185 cm in length.  Other snakes, such as water snakes, can appear thicker bodied than gray ratsnakes.  Hatchling Gray Ratsnakes have a pattern of dark grey or black blotches and spots over a background of light gray. As the snake ages, this pattern fades and adults are predominantly black. The underneath of the chin and throat are usually white, often mottled with grey and black blotches.  

Note the dark black/gray top and the noticeably white chin and underside.

Note the distinct dark gray blotches over a lighter gray.
