Overview
The common egg-eating snake is a small African colubrid uniquely specialized to feed exclusively on bird eggs, an extreme dietary specialization rare among snakes. Its skull and vertebrae are adapted to crack open eggs internally after swallowing them whole.
Despite lacking functional teeth for typical prey capture, it is a highly successful species across much of sub-Saharan Africa, often mimicking venomous snakes for defense.
How to identify it
- Slender body, gray, brown, or reddish with irregular dark blotches or chevrons
- Small head, barely wider than the neck, with virtually no visible teeth
- Rough, keeled scales along the body
- Elastic jaw and skin allowing the mouth to stretch around eggs far wider than the head
- Distinguished from venomous look-alikes by lack of a triangular head and by rasping, coil-rubbing defensive display rather than a hood or rattle
Habitat & range
Found in savanna, grassland, scrub, and farmland across sub-Saharan Africa, often near bird nesting sites where eggs are seasonally abundant.
Behavior, diet & reproduction
Nocturnal, searching by scent for bird nests, then swallowing eggs whole before using specialized bony projections in the throat to crack the shell internally, regurgitating the crushed shell afterward. Displays a rasping, coil-rubbing bluff when threatened, mimicking venomous species. Egg-laying, with small clutches.
Frequently asked questions
Is the egg-eating snake venomous?
No, it is entirely non-venomous and relies on mimicry and bluff displays for defense.
How does it eat eggs larger than its head?
Its jaws and skin stretch remarkably, and internal bony projections crack the shell after the egg is swallowed whole.
Does it eat anything besides eggs?
No, its diet consists almost exclusively of bird eggs.
How does it defend itself without venom?
It rubs its rough scales together to produce a rasping sound, mimicking the hiss of venomous snakes, as a bluff display.
