Rhamphiophis oxyrhynchus, commonly known as the rufous beaked snake, is a species of mildly venomous colubrid, which is endemic to West Africa. It is named for its hooked snout, which it uses to dig burrows, and for its reddish-brown back scales. It hunts small animals during the day with the help of its venomous bite.
The rufous beaked snake is large and stout, with males reaching a maximum length of 1.1 m (3.6 ft) and females reaching 1.07 m (3.5 ft). It has a shortened skull, as with all beaked snakes, giving it a clear distinction between its head and body, as well as a dark brown eyestripe running down the side of its head. Its eyes are large with round pupils. While its back tends to be yellowish-brown to reddish-brown, its belly is cream or yellowish-white.
