Australian Tiger Snake
It is the 5th most venomous snake in the world.
The snake's large size, often aggressive defense and toxic venom make it extremely dangerous to humans.
Although generally shy and preferring escape over conflict, a cornered tiger snake will put on an impressive threat display by holding its forebody in a tense, loose curve with the head slightly raised and pointed at the offender. It will hiss loudly as it inflates and deflates its body, and if provoked further will lash out and bite forcefully. The venom of the tiger snake is strongly neurotoxic and coagulant, and anyone suspected of being bitten should seek medical attention immediately.
