Key identifying features
The Eastern Brown Snake (Pseudonaja textilis) is a slender to moderately built elapid with a narrow head barely distinct from the neck, large eyes with round pupils, and smooth scales. It is considered one of the most medically significant snakes in Australia due to its widespread distribution near populated areas.
Coloration & pattern
Coloration is highly variable, ranging from light tan or orange-brown to dark brown, gray, or even nearly black, sometimes with faint darker banding, especially in juveniles, which may show more distinct dark bands or a dark cap on the head that fades with age. The underside is cream or yellowish, typically marked with irregular orange or brown spots or blotches, a useful identifying feature.
Head, eyes & scales
The head is narrow, only slightly wider than the neck, with large, prominent round eyes. Scales are smooth, and coloration on the head generally matches or is only slightly different from the body, without the pronounced pale head contrast seen in the King Brown Snake.
Size & body shape
Adults typically reach 1.5–2 meters (5–6.5 feet), with a slender, streamlined body adapted for rapid movement, notably faster and more agile in the field than the bulkier King Brown Snake.
Range & habitat where you'll see it
The Eastern Brown Snake is widespread across eastern and central Australia, including agricultural land, grassland, woodland edges, and areas near human habitation, where it is frequently encountered due to its tolerance of disturbed environments and abundance of rodent prey.
How to tell it apart from look-alikes
Its slender build, narrow head, and variable but generally more uniform brown coloration (without a strongly paler head) distinguish it from the bulkier King Brown Snake, which has a noticeably paler head and thicker, more reticulated body. Juvenile Eastern Brown Snakes with banded patterns can resemble other juvenile elapids, but the combination of orange-spotted cream belly and slender build assists identification.
