Eastern Brown Snake

The eastern brown snake (Pseudonaja textilis), often referred to as the common brown snake, is a species of genus Pseudonaja. This snake is considered the second most venomous land snake based on its LD50 value (SC) in mice. It is native to Australia, Papua New Guinea and Indonesia.

Adult eastern brown snakes are highly variable in colour. Whilst usually a uniform shade of brown, they can have various patterns including speckles and bands, and range from a very pale fawn colour through to black, including orange, silver, yellow and grey. Juveniles can be banded and have a black head, with a lighter band behind, a black nape, and numerous red-brown spots on the belly.

This species has an average length of 1.5–1.8 m and it is rarely larger than 2 m. Large eastern brown snakes are often confused with "king brown" snakes (Pseudechis australis), whose habitat they share in many areas.
