Key identifying features
The black-headed centipede-eater (Aparallactus capensis) is a small, secretive burrowing snake identified primarily by the strong contrast between its glossy black head and a body that is typically reddish-brown, orange-brown, or tan, giving it a distinctive two-toned appearance unusual among small African snakes.
Coloration & pattern
The head and often a short section of the neck are glossy black, sharply demarcated from the body color, which is generally uniform reddish-brown, orange, or light tan without bands, blotches, or other markings. The underside is typically paler, cream to yellowish, without strong patterning.
Head, eyes & scales
The head is small, narrow, and not distinct from the neck, typical of burrowing snakes, with a somewhat rounded snout adapted for pushing through loose soil and leaf litter. The eyes are small with round pupils, reflecting its largely fossorial, low-light lifestyle. Scales are smooth and glossy, contributing to its sleek appearance.
Size & body shape
This is a small snake, with adults typically reaching only 8 to 14 inches in length. The body is slender and cylindrical throughout, tapering gently to a short, pointed tail, an overall shape well suited to moving through soil, leaf litter, and under surface debris.
Range & habitat where you'll see it
The black-headed centipede-eater is found across much of southern and eastern Africa, including South Africa, Zimbabwe, and neighboring countries, typically in savanna, grassland, and woodland habitats. It is a secretive, mostly nocturnal species usually found under logs, rocks, leaf litter, or loose soil rather than moving in the open, and as its name suggests, it specializes in preying on centipedes.
How to tell it apart from look-alikes
Other small reddish-brown burrowing snakes in the same region generally lack the sharply contrasting glossy black head, which is the most distinctive feature of this species. Purple-glossed snakes, another centipede-specialist group, tend to have a more uniformly glossy purplish-brown body without the same stark black-and-orange head-body contrast. The combination of small size, smooth cylindrical body, and a well-defined black head against a plain reddish-brown body is generally sufficient for identification.
Frequently asked questions
What is the most distinctive feature of the black-headed centipede-eater?
A glossy black head that contrasts sharply with a reddish-brown to orange, unmarked body.
How big does this species get?
It is quite small, with adults typically reaching only 8 to 14 inches in length.
Where would you typically find one to observe it?
Under logs, rocks, leaf litter, or loose soil in savanna, grassland, and woodland habitats across southern and eastern Africa, mostly at night.
How is it different from other small reddish burrowing snakes?
Its sharply contrasting glossy black head is more pronounced than in similar species, making the head-body color contrast the key identifying feature.
