Are eastern brown snakes dangerous?

The Eastern Brown (Pseudonaja textilis), also known as the Common brownish snake is a venomous elapid snake found in the eastern half of Australia, but in Tasmania. There are no subspecies recognized.

​The species can also be found in Eastern Papua New Guinea but only in very limited numbers. Based on its LD50 value (subcutaneous) it is regarded as the world’s second most venomous property snake, only after the inland taipan.

The Eastern Brown can be found in many types of habitats from Eucalypt forests, pasturesand coastal heathlands, savannah woodlands, arid shrublands and internal grasslands. They also have adapted to grazed, farmed and semi-urban surroundings.

These snakes are diurnal, which means they most active during the day, particularly on hot sunny days, making them probably the most frequently encountered venomous snake in Australia.

All these are agile and fast-moving snakes, searching through the day and returning into its burrow during the nighttime. During winter with colder temperatures that they stay in their burrows for a period of 5 or 4 weeks.

They are generally orange or brown in color, but there are many variations in color ranging from lighter to darker brown to almost black. The stomach is orange or yellow, a lotion, and frequently speckled with gray blotches.

The southern brown snake has a mean length between 3.6 to 5.9 feet (1.1 to 1.8 m). Any snake measuring over 6.6 ft (2 m) is believed extraordinarily big, however, the highest recorded length for those species is 7.9 feet (2.4 m). They have a slim body, using a short and curved head. The males grow bigger than females.

The Eastern Brown predators include birds of prey and feral cats, and the appear to have resistance to the venom of the Mulga Snake (Pseudechis australis) a potential predator.

Yet like several other Australian species they are not so immune to the poison of the plant toad and die from ingesting them. In captivity, they lived for as long as 7 to a decade, although the Eastern Brown life in the wild is unknown.​

Can a brown snake kill you?

The oriental brown is considered the 2nd most venomous snake in the world, exceeded only by the inland taipan (Oxyuranus microlepidotus). But contrary to the inland taipan, the Eastern Brown’s habitat involves some of Australia’s most populated areas, which places them in touch with individuals more frequently.

Compared to some other snake species like cobras and vipers, the Eastern Brown has quite short fangs, just about 3mm in length. Even though they may bite a few times if triggered, they inject a very small quantity of venom, roughly 4 mg, but that is enough to kill a human.

Their venom has a subcutaneous LD50 range of 36.5 into 53 μg/kg comprising for the most part of neurotoxins and blood coagulants.The symptoms include collapse, convulsions, nausea, dizziness, renal failure, paralysis and cardiac arrest, and without proper medical treatment, bites can prove deadly.

Because of this they’re responsible for deaths brought on by snake bites in Australia, but with effective first-aid treatment and antivenom, there are usually only 1 or 2 deaths each year.

What do brown snake eat?

The eastern brown feeds mostly on small mammals, in particular rodents, the introduced rats and mice and because of this it’s often found around farm buildings. However they feed on frogs, lizards, birds, birds and they even feed on other snakes.

Smaller and younger snakes eat more ectothermic prey, like lizards, although the larger ones mostly have warm-blooded prey.


The Eastern Brown breeding season begins in mid to late spring. The males will engage to gain the right to partner with open minded females. They’ll intertwine closely with each male trying to push down and overpower another, these”fights” can endure for an hour or even longer.

The species is oviparous and females lay up to 25 eggs in late spring or early summer, but the average clutch is about 15 eggs. The hatchlings dimensions at birth varies both within and among ranging from 7,5 to 11 inches, and they are entirely independent from the mom. The sexual maturity in the species may be attained in 3 or just 2,5 years.


Exactly like all other Australian snake species, the Eastern Brown is protected by law, therefore killing or capturing is illegal. Brown Snake is a really adaptable species. It’s capable of areas and consumes an exotic food supply, the introduced rats and mice, hence the species potential conservation seems assured.

Even so many Eastern Brown snakes fall victim to road kill every year and many others have been killed on sight by farmers and landowners. They also play a very useful role for farmers by controlling the population of rodent pests that are introduced.
