Also called the Clarence River snake, the rough-scaled snake is found in isolated pockets along the coast of Queensland and northern New South Wales. It is usually found close to water and is active during the day, feeding on frogs and mice. The scales are keeled (hence the name rough-scaled snake) and the body usually greenish brown with dark bands on the back. Average length is about 0.71m, maximum 1.07m. It is sometimes mistaken for the harmless keelback (Amphiesma mairii).
