The common death adder (Acanthophis antarcticus) is a type of snake found in Australia. It belongs to the snake family called Elapidae.
The common death adder is known for being one of the most venomous land snakes in Australia and around the world. Even though it's still found in many places, it's facing a growing danger from the cane toads that have invaded Australia.

What Does It Look Like?
Unlike many other snakes that are long and thin, the death adder has a short, thick, and sturdy body. It usually grows to be about 70 to 100 centimeters long. Its skin is covered in patterns of brown, grey, and reddish-orange, which act like a perfect camouflage. When it lies on the forest floor, among the dry leaves and dirt, it becomes almost invisible to the human eye. This is a very important survival skill!
Where Do They Live?
Common death adders live in many parts of eastern and coastal southern Australia. You can find them in Queensland, New South Wales, Victoria, and South Australia. They are less common in the Northern Territory and Western Australia. They also live in Papua.
These snakes like to live in forests, woodlands, grasslands, and heathlands along Australia's eastern coast. They are very good at hiding! Their striped patterns help them blend in with leaves and other things on the ground.
What Do They Eat?
Common death adders mostly eat small mammals and birds. Unlike many other snakes, they don't chase their food. Instead, they wait patiently for prey to come by, sometimes for many days!
They hide themselves under leaves, making it hard to see them. They coil up and twitch their tail, which looks like a small worm. This tricks other animals into coming closer to investigate. When an animal gets close enough, the death adder strikes very quickly. It injects its venom, then waits for the animal to die before eating it.
Life Cycle and Growth
Common death adders have a very interesting way of starting their lives. Unlike many other snakes that lay eggs, the common death adder gives birth to live young. This is called being "viviparous."
A mother can give birth to a litter of about 10 to 20 babies at once. When they are born, the baby snakes are already fully formed and ready to hunt. They are tiny, but they have the same instincts as their parents. They know exactly how to wiggle their tails to lure in small insects or tiny lizards.
As they grow, they shed their skin many times. Shedding is a process where the snake grows a new layer of skin underneath the old one, and then wiggles out of the old skin. This allows them to grow bigger and stronger as they get older.
Behavior
The common death adder is a nocturnal animal. This means it prefers to be active at night when the world is cooler. During the hot Australian day, the snake hides in cool, shady spots, such as under logs, rocks, or thick piles of leaves.
Being nocturnal helps the snake in two ways:
- Temperature Control: Australia can get very hot during the day. By staying hidden during the day, the snake avoids the intense sun and keeps its body temperature at a comfortable level.
- Hunting Success: Many of the animals the death adder likes to eat, such as small rodents and frogs, are also active at night. By hunting when its prey is out, the snake has a much better chance of finding a meal.
Defense Mechanisms
Even though the death adder is a predator, it also has to worry about being eaten by larger animals like birds of prey or monitor lizards. Because it is not a fast mover, it cannot run away from danger. Instead, it relies on its camouflage.
If a predator gets too close, the death adder’s first choice is to stay perfectly still and hope it isn't seen. If the predator gets even closer, the snake might flatten its body to look bigger or hiss to warn the intruder to stay away. It really does not want to fight; it would much rather be left alone. It only uses its venom as a last resort to protect itself.
Threats to Death Adders
Two main problems threaten common death adders. One is the loss of their natural homes. The other is the spread of invasive cane toads in Australia. Young death adders can be eaten by the toads. Also, adult death adders that eat the toads get poisoned by their skin. This poison is very dangerous to Australian reptiles and can kill the snakes.
Staying safe
Death adders are not usually aggressive towards humans. However, because they hide under dry leaves, people walking in the bush might accidentally step on them. When visiting the Australian bush, it is always smart to wear thick boots and stay on clear trails.
About Their Venom
The common death adder's venom is very strong. It contains a powerful substance called a neurotoxin. This neurotoxin can cause paralysis, which means the body can't move, and it can even lead to death. If a person is bitten, serious problems can happen within six hours.
Amazing Facts About Common Death Adders
- They have the longest fangs of any snake in Australia!
- These snakes can strike faster than any other venomous snake in Australia. Their strike is so fast that it can be completed in less than 0.15 seconds. That is faster than you can blink your eyes!
- The common death adder was first described in 1802. A scientist named George Shaw gave it the name Boa antarctica.
- Even though they look like vipers (a type of snake with a triangular head), they are actually elapids.
- They can wait for up to a week in the exact same spot for a meal to pass by.
