9. Death Adder
Region: Australia, New Guinea and nearby islands

They also have vertical pupils and many small scales on the top of the head. Their fangs are also longer and more mobile than for most other elapids, although still far from the size seen in some of the true vipers.

Saw-scaled viper is a venomous viper species found in parts of the Middle East and Central Asia, and especially the Indian subcontinent.

Five subspecies are currently recognized, including the nominate subspecies described here.

2. Eastern Brown Snake
Region: Australia
Region: Australia
The eastern 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.
The Inland Taipan, also known as the Small Scaled Snake and Fierce Snake, is native to Australia and is regarded as the most venomous land snake in the world based on LD50 values in mice. It is a species of taipan belonging to the Elapidae family. Although highly venomous, it is very shy and reclusive, and always prefers to escape from trouble (the word "fierce" from its alternate name describes its venom, not its temperament).
Important note: Most people don’t understand that there is a difference between an organism being venomous or poisonous.
Venomous creatures inject a toxin, usually from an internal gland, while poisonous creatures typically secrete a toxin externally. Hence poisonous creatures are most dangerous when touched or ingested.
