[edit] Appearance

Adult Eastern Brown Snakes are uniformly brown in colour. Juveniles have a black head, with a lighter band behind, a black nape, and numerous red-brown spots on the belly. Occasionally they have dark cross-bands. They have 17 rows of mid-body scales, a divided anal scale and 45–75 divided sub caudal scales. Adults generally range up to 2 metres in length.

[edit] Range

The Eastern Brown Snake is found all the way along the east coast of Australia, from the tip of Cape York, along the coasts and inland ranges of New South Wales, Victoria and South Australia. Some specimens can be found in arid areas of the Northern Territory. There are also very limited numbers in Papua New Guinea. Due to its diet for mainly rodents, it can be found near houses and farms.

[edit] Habitat

The Eastern Brown Snake occupies a varied range of habitats from wet to dry sclerophyll forests (Eucalypt forests) and heaths of coastal ranges, through to savannah woodlands, inner grasslands and arid scrublands. It will not be found in rainforests or wet areas.

[edit] Diet

The Eastern Brown snake is diurnal, meaning it is active during the day, especially on warm sunny days where it will bask in the sun. Its diet consists of eggs and small mammals; especially rodents such as mice and rats and may also eat other reptiles and frogs.

[edit] Defences

[edit] Stance

Eastern Brown Snakes are very fast moving and highly aggressive. When agitated, they will hold their necks high, appearing in a somewhat upright S-shape. The snake will occasionally chase an aggressor and strike at it repeatedly.

[edit] Venom

The Eastern Brown Snake is the second most venomous land snake in the world after the Inland Taipan.[1] Although Eastern Browns will seek to avoid a confrontation, it has a very toxic venom, and when bitten can cause death. Sub-adults have been known to cause fatalities in humans.

[edit] Reproduction

Eastern Brown Snakes mate during spring. where males can be found to engage in 'ritual combat' with another male to dominate and displace the other's territory. The most dominant male will mate with females in the area, to which the female will produce a clutch of 10-40 eggs in late spring or early summer.
