The species grows to about 65 cm and has a pale body densely covered with red-brown spots, with a few dark saddle blotches on the back. It inhabits rocky reefs and is usually solitary and shy; juveniles are often seen in tide pools. As an ambush predator it feeds mainly on crabs and other crustaceans, and on fishes.
