Eastern brown snake


Eastern brown snake (Pseudonaja textilis), often referred to as the common brown snake, is a species of venomous snake in the family Elapidae. The species is native to eastern and central Australia and southern New Guinea. It is considered the second-most venomous terrestrial snake in the world after the Inland taipan. The Eastern brown snake plays a pivotal role in its ecosystem, controlling rodent populations. However, it is also notorious for its aggression and potent venom, making it a significant concern for human populations in its native range.

Description[edit | edit source]

The Eastern brown snake ranges in color from very pale fawn to almost black, depending on the individual and the region it inhabits. It has a slender build and can reach up to 2 meters in length, though most specimens are much smaller. The snake's head is small and indistinct from its body, and it has large eyes with round pupils. Juveniles may exhibit a black head and nape with a lighter band behind, a feature that usually fades as they mature.

Habitat and Distribution[edit | edit source]

This species is highly adaptable and can be found in a variety of habitats, including forests, savannas, scrublands, and grasslands, as well as within human-modified areas such as farms, parks, and gardens. Its distribution spans from the eastern coast of Australia, extending into central regions, and into southern parts of New Guinea.

Behavior[edit | edit source]

Eastern brown snakes are diurnal, meaning they are active during the day. They are known for their agility and speed. When threatened, they may display aggressive behavior, including flattening their necks, hissing, and striking with little provocation. Despite their aggression, they often prefer to flee from threats if given the opportunity.

Diet[edit | edit source]

Their diet primarily consists of small mammals, particularly rodents, making them beneficial for controlling pest populations. They also consume birds, eggs, and other reptiles, including smaller snakes.

Venom[edit | edit source]

The venom of the Eastern brown snake is highly toxic and contains neurotoxins, coagulants, and cardiotoxins. A bite from this snake can lead to paralysis, uncontrollable bleeding, and if not treated promptly with antivenom, can be fatal. Due to its potent venom and proximity to populated areas, the Eastern brown snake is responsible for the majority of snakebite deaths in Australia.

Reproduction[edit | edit source]

Eastern brown snakes are oviparous, laying clutches of 10 to 35 eggs, usually in the shelter of logs or burrows. The eggs hatch after about two months, with the juveniles being fully independent from birth.

Conservation Status[edit | edit source]

Currently, the Eastern brown snake is not considered to be at risk of extinction and is classified as of Least Concern by the International Union for Conservation of Nature (IUCN). However, like many species, it faces threats from habitat destruction and fragmentation.

Interaction with Humans[edit | edit source]

Due to their venom potency and tendency to inhabit areas close to human dwellings, Eastern brown snakes are considered a significant wildlife hazard. Education on snake behavior and the importance of prompt medical treatment for bites is crucial in areas where these snakes are common.
