Open encyclopedia reference
The spotted mulga snake (Pseudechis butleri), also known commonly as Butler's black snake and Butler's snake, is a species of venomous snake in the family Elapidae. The species is endemic to Western Australia. It is a member of the genus Pseudechis, dangerously venomous snakes that can intimidate an opponent by raising the head and presenting a hood. This cobra-like threat display is supported by the ability to produce a very large amount of venom.
