Key identifying features
The Black-Naped Snake (Neelaps bimaculatus) is a small, slender, fossorial elapid found in southern and western Australia. Its defining feature is a distinct dark, often black, patch or band across the nape of the neck, set against an otherwise plain, lightly colored body — a striking contrast that gives the species its common name.
Coloration & pattern
The body is usually pale brown, tan, or cream, often unmarked or only very faintly patterned along its length. The most notable marking is the dark nape band, which may appear as a solid black patch or a narrow black collar just behind the head. In some individuals a second, fainter dark marking may occur further back, but the nape patch is the most consistent and visible field mark.
Head, eyes & scales
The head is small, rounded, and barely distinct from the neck, typical of burrowing elapids adapted to moving through loose soil. The snout is blunt and rounded. Eyes are small with round pupils. Scales are smooth and glossy across the body, aiding subsurface movement.
Size & body shape
This is a small species, generally reaching 20 to 30 cm (8 to 12 inches) in total length. The body is thin and cylindrical, tapering to a short tail, consistent with a life spent largely underground or beneath surface litter.
Range & habitat where you'll see it
The Black-Naped Snake is found across southern and western Australia in sandy or loamy soils within woodlands, shrublands, and semi-arid habitats. It shelters beneath logs, rocks, leaf litter, and loose soil, and is nocturnal and fossorial, so it is rarely observed moving in the open.
How to tell it apart from look-alikes
The distinct dark nape patch against an otherwise plain, unmarked body is the most reliable way to distinguish this species from other small Australian burrowing snakes, such as bandy-bandies (which have bold black-and-white body banding) or other Neelaps and Simoselaps species. Its small size, smooth scales, and blunt rounded head further separate it from larger elapids, while the absence of body banding differentiates it from more strikingly ringed species.
Frequently asked questions
What is the key identifying mark of the Black-Naped Snake?
A dark black patch or band across the nape of the neck, contrasting sharply with its otherwise plain, lightly colored body.
Does this snake have banding along its whole body?
No, the body is generally plain and unmarked; the dark marking is concentrated at the nape rather than forming full body bands.
How large does the Black-Naped Snake grow?
It is small, typically only 20 to 30 cm (8 to 12 inches) long.
Where in Australia is it usually found?
In southern and western Australia, in sandy or loamy soils within woodlands and semi-arid shrublands.
How can it be distinguished from a bandy-bandy?
Bandy-bandies have bold black-and-white bands along the entire body, while the Black-Naped Snake is plain-bodied with only a dark nape patch.
