King brown snake.
The king brown snake (Pseudechis australis) is a species of highly venomous snake of the family Elapidae, native to northern, western, and Central Australia. Despite its common name, it is a member of the genus Pseudechis (black snakes) and only distantly related to true brown snakes. First described by the English zoologist John Edward Gray in 1842, it is a robust snake up to 3.3 m (11 ft) long. It is variable in appearance, with individuals from northern Australia having tan upperparts, while those from southern Australia are dark brown to blackish. The dorsal scales are two-toned, sometimes giving the snake a patterned appearance. Its underside is cream or white, often with orange splotches. The snake is considered to be a least-concern species. Its venomous bites often produce extensive pain and swelling, and deaths have been recorded, most recently in 1969. Its victims are treated with black-snake (not brown-snake) antivenom.
