Read on to learn more about ten of the most fascinating snakes in Australia.
1. Australian Scrub Python

Scrub pythons are the longest and heaviest snakes in Australia. They can reach lengths of 25 feet, and weigh over 50 pounds. They have mottled light and dark brown coloring with a long, heavy head. Scrub pythons aren’t venomous. Instead, they rely on constricting their prey to death before swallowing it whole. Typical food items include rodents, possums, baby kangaroos, and even fruit bats.
2. Eastern Brown Snake

Eastern brown snakes are venomous and have small fangs for their size, but that doesn’t stop this species from causing more deaths from snakebites in Australia than any other snake. These snakes can grow up to six feet long. As their name suggests, their coloring ranges from light to dark brown. They prefer to eat rodents, but will also eat reptiles, amphibians, and birds.
3. Coastal Taipan

Coastal taipans are long snakes that can grow to over nine feet long. They have a deadly bite and are wildly unpredictable. Where most snakes would rather flee than fight when it comes to humans, the coastal taipan might just follow you. They range from yellow-brown to black, with their coloring fading in the summer, and darkening in the winter. Unlike other snakes, coastal taipans only eat warm-blooded creatures, like rodents, birds, and bandicoots. They’re active during the day in all but the hottest months when they become more nocturnal.
4. Bandy-Bandy Snake

These snakes are one of the most instantly recognizable snakes in Australia. They’re distinguished from other snakes by their stark black and white stripes. These snakes rarely exceed 2.5 feet in length, though their venom is strong enough to kill a human. However, bandy-bandy snakes rarely attack humans, or even mammals, preferring instead to eat mainly other reptiles and amphibians. They’re one of Australia’s most iconic and loved snakes.
5. Red-Bellied Black Snake

Red-bellied black snakes are one of the most misunderstood snakes in Australia. They’re venomous, though their venom poses little risk to humans, and can reach lengths of over six feet. As their name suggests, their sides and back are black, and their undersides are red or orange-red. Unfortunately, they’re often killed by fearful people, even though they’re harmless to humans. These snakes eat everything from amphibians and reptiles to rodents and fish. They’re known to flee into freshwater when predators come too close.
6. Tiger Snake

Despite their beauty, tiger snakes are one of the deadliest snakes in Australia. They can grow up to six feet long and have narrow heads with black eyes. They’re characterized by alternating black and yellow stripes that run from head to tail. Their diet consists of just about everything small enough to swallow, including rodents, amphibians, and reptiles.
7. Common Death Adder

One of the shortest, thickest-bodied snakes in Australia, the common death adder tops out at around three feet in length. They’re highly venomous, with diets that largely consist of small mammals and birds. Death adders have heavy bodies characterized by alternating bands of light and dark scales that range from brown to gray.
8. Inland Taipan

These snakes are often confused with brown snakes. Inland taipans have one of the deadliest venoms in the world, yet they’re secretive and non-aggressive, and live only in remote areas, so bites to humans are rare. They range in color from light brown to dark brown, with darker heads and necks. They grow to around 6.5 feet in length and eat only small mammals.
9. Pygmy Python

Pygmy pythons grow to a short two feet long. They’re non-venomous and rely on constriction to kill their prey. Pygmy pythons are red to orange in color, with small, dark, regular blotches and orange eyes. They eat small mammals.
10. Black-Headed Python

Black-headed pythons can grow to nearly 11 feet long. Like all pythons, they have heavy bodies with narrow heads. Their bodies are pale brown in color, with subtle, darker markings. Black-headed pythons are so named for the black coloring on their head and neck. These snakes eat mostly reptiles with some small to medium-sized mammals.

Other Dangerous Animals Found In Australia

Australia is home to a multitude of spiders that look more deadly than they actually are. One spider that has more than 40 different species, some of which are not dangerous, is the funnel-web spider. While there are many in this family that are not dangerous, there is one that is highly toxic and whose bite is treated the same as a snake bite – the Sydney Funnel-web spider. A dark-brown to black spider with silk-spinning organs at the bottom of its abdomen, this arachnid has a venom that is one of the most toxic to humans and was responsible for a reported 13 deaths, although, since the introduction of an anti-venom in the early 1980s, there have been no reported deaths.

It doesn’t seem like a snail would be dangerous but the Textile Cone Snail, found in Australia, is a venomous animal that uses conotoxin to kill its prey. Also known as the Cloth of Gold, this snail uses its harpoon-like tooth to inject venom through microscopic needles that are not only powerful enough to pierce the skin of a human but can puncture wetsuits and gloves. This snail contains enough venom to wipe out 60 adults, although there have only been a handful of reported deaths throughout the world.
