Eastern Brown Snake

The Eastern Brown Snake is widely regarded as one of Australia's most medically significant venomous snakes due to its potent venom, wide distribution, and frequent proximity to human populations in agricultural and suburban areas. It ranges across much of eastern and central Australia and into southern New Guinea.

Its slender build and swift, nervous movements distinguish it behaviorally from the bulkier elapids it shares habitat with, and its coloration can vary considerably across its range.

• Coloration highly variable, ranging from pale tan or gray-brown to dark brown or almost black; juveniles often display banding that fades with age
• Slender, moderately long body with a narrow head barely distinct from the neck
• Round pupils
• Smooth scales
• Pale cream to yellowish belly, sometimes with orange or gray blotches
• Distinguished from the King Brown Snake (Mulga Snake) by its more slender build, narrower head, and generally more nervous, quick-moving behavior

Common in open woodlands, grasslands, farmland, and even urban fringe areas across eastern and central Australia, thriving particularly in agricultural landscapes with abundant rodent prey, and also found in parts of southern New Guinea.

Diurnal and fast-moving, often seen basking or actively foraging during the day. Preys primarily on rodents but also takes small mammals, birds, and other reptiles, actively pursuing prey rather than relying solely on ambush. Oviparous, laying eggs in warm, sheltered sites. Known for a distinctive defensive posture involving raising the forebody in an S-shape when threatened, and capable of rapid, repeated strikes.
