The red-bellied black snake (Pseudechis porphyriacus) is a species of elapid snake native to eastern Australia. Though its venom is capable of causing significant morbidity, a bite from it is not generally fatal and is less venomous than other Australian Elapid snakes. It is common in woodlands, forests and swamplands of eastern Australia. It is one of Australia's best-known snakes, as it is common in urban areas along the eastern coast of Australia. It has an average total length (including tail) of 1.5 to 2 metres (4 ft 11 in to 6 ft 7 in).
porphyritic porphyritic was first described by George Shaw in Zoology of New Holland (1794), placing it in the genus Clubber. He believed the snake to be harmless to people. The accompanying illustration was attributed to James Sowerby, but is regarded as being produced from drawings by John White. The genus Pseudechis was created for it by Johann Georg Wagler in 1830, though several subsequent species have been added. Snake expert Eric Worrell analyzed the skulls of the genus and found that of the red-bellied black snake to be the most divergent.
The red-bellied black snake is glossy black on the dorsal surface and red, crimson or pink in colour on the lower sides and belly. The snout is often a lighter brown colour. It is a relatively large species of snake reaching up to 2 metres (6 ft 7 in) in total length (including tail), with an extreme example measuring 2.5 metres (8 ft 2 in), although an average sized specimen would be closer to 1.4 metres (4 ft 7 in). Like all Elapid snakes it is front fanged. It has 17 mid-body scale rows. Juveniles are similar to the eastern small-eyed snake, with which it can be easily confused.
Distribution and habitatEdit
The red-bellied black snake is native to the east coast of Australia. It can be found in the urban forest, woodland, plains and bushland areas of the Blue Mountains, Canberra, Sydney, Brisbane, Melbourne, Cairns and Adelaide. It is most commonly seen close to dams, streams, billabongs and other bodies of water.
Disposition and behaviourEdit
Psuedechis porphyriacus is generally not an aggressive species. However, when provoked, it will recoil into its striking stance as a threat, but will try to escape at the first opportunity. It is most active by day. When not hunting or basking it may be found beneath timber, rocks and rubbish or down holes and burrows.
The venom of red-bellied black snake consists of neurotoxins, mycotoxins, coagulants and also has haemolytic properties. Bites from red-bellied black snake are rarely life-threatening due to the snake usually choosing to inject little venom toxin, but are still in need of immediate medical attention. Tiger snake antivenom is used to treat bites. While black snake antivenom can be used, tiger snake antivenom can be used at a lower dose. The smaller dose is cheaper to produce, and is less likely to cause a reaction in the patient. Patients may suffer anosmia. 
Red-bellied black snakes are ovoviviparous; that is, they give birth to live young in individual membranous sacs. The young, numbering between eight and forty, emerge from their sacs very shortly after birth, and have an average length of about 122 millimetres (4.8 in). In the wild, few will survive to reproduce.
