Notechis is a genus of highly venomous elapid snakes found in Australia. They are commonly known as tiger snakes. There are two species.

[edit] Description

The Common Tiger Snake is typically banded, dark brown above with a yellow to olive belly. N. ater subspecies found away from mainland Australia are usually uniformly black. However, as with most snakes, the colours vary widely between individuals and are an unreliable means of identifying species. Tiger snakes give live birth to around 30 young at a time. The Tasmanian tiger snake has two fangs in the top corners of upper jaw

The Tasmanian tiger snake has been proved to be the same species as what occurs on the south-eastern Australian mainland, Notechis scutatus. The markings are extremely variable and should not be used in isolation to identify snakes. Colours: jet black, yellow/orange with grey bands and sandy grey with no bands. There are also unconfirmed reports of a red bellied tiger snake in north-east Tasmania. While they are commonly found in these areas, their numbers are diminishing. In most states they are protected species and to kill or injure one attracts a fine of up to $4000.
