The red-bellied black snake (Pseudechis porphyriacus) is a species of venomous snake in the family Elapidae. The species is indigenous to Australia. Originally described by George Shaw in 1794 as a species new to science, it is one of eastern Australia's most commonly encountered snakes. Averaging around 1.25 m (4 ft 1 in) in total length (tail included), it has glossy black upperparts, bright red or orange flanks, and a pink or dull red belly. It is not aggressive and generally retreats from human encounters, but will defend itself if provoked. Although its venom can cause significant illness, no deaths have been recorded from its bite, which is less venomous than other Australian elapid snakes. The venom contains neurotoxins, myotoxins, and coagulants and has haemolytic properties. Victims can also lose their sense of smell. Common in woodlands, forests, swamplands, along river banks and waterways, the red-bellied black snake often ventures into nearby urban areas.
