Inland Taipan Snake Facts

Inland Taipan Profile

The inland taipan (Oxyuranus microlepidotus) is the most venomous snake in the world. The venom of one bite is strong enough to kill 100 men.

Inland Taipan Facts

They are native to central and eastern Australia in dry areas and are commonly known as the western taipan, the small-scaled snake, or the fierce snake.

Inland Taipan Facts Overview

Habitat: Dry, open plains
Location: Central and Eastern Australia
Lifespan: 10-15 years
Size: Average 2m, can reach 2.7m
Weight: 1-2kg
Color: Dark tan or light brownish
Diet: Mammals, most often rats
Predators: The mulga snake
Top Speed: Unknown
No. of Species:
Conservation Status:
Least concern

They hunt mammals, specifically various species of rat, with venom that is designed to be deadly to warm-blooded animals. They are most active during the cool hours of the morning and stay in the shade for the rest of the day.

While they are the most venomous, they are not the deadliest snake as they rarely come into contact with humans. There have been no recorded deaths since the creation of the anti-venom in 1955.

They are solitary, coming together only to mate. Females lay 12-24 eggs in crevices or abandoned burrows.

Interesting Inland Taipan Facts

1. They are the most venomous of all snakes

Tests using human cell cultures show that they are the most venomous of all tested snakes. The venom in one bite is thought to be enough to kill 100 adults. 1

2. They have evolved specifically to kill mammals

This is what makes them so venomous to humans as the toxins in their venom are designed to be deadly to warm-blooded animals. Symptoms of a bite include headache, vomiting, stomach pain, collapse, and convulsions.

3. They rarely bite people

So, while they are the most venomous, they are not the deadliest snake. This is because they live in areas where there aren’t many people. 2

4. The anti-venom was developed in 1955

An amateur studier of snakes called Kevin Budden was the first person to catch a live taipan snake and died in the process. His research was key for developing the anti-venom. 3

5. There have been no recorded deaths since the creation of the anti-venom

Essentially all bites from the inland taipan in recent years have been herpetologists studying the snakes, and none of these have been fatal.

6. They are not aggressive

Reptile handlers consider them relatively easy to work with as they are rarely aggressive. When encountering humans in the wild, they are most likely to run away.

7. They attack fast and strike up to 8 times

They strike at lightning-fast speed, with as many as 8 bites in one attack.

8. Their colour changes with the seasons

They become lighter in summer and darker in winter. This helps them regulate their temperature as darker colours absorb more heat, helping them stay warm in winter.

9. They have only one predator, the mulga snake

The mulga snake (Pseudechis australis) eats multiple snake species and is immune to the venom of the inland taipan snake.

10. They compete with large monitor lizards for food

The perentie is the largest monitor lizard in Australia. These giant lizards will aggressively compete with the inland taipan for food.

11. They lay 12 -24 eggs

They lay these eggs in abandoned burrows and they take 2 months to hatch.

12. They are protected by law, and designated ‘least concern’ on the IUCN Red List

Every snake in Australia is protected by law, and despite some habitat destruction, their population is not considered to be in decline.
