Common Egg-eater

The common egg-eater is a highly specialized African colubrid with a diet consisting entirely of bird eggs, an unusual feeding niche among snakes. It has weak or nonexistent teeth, having instead evolved projections from its neck vertebrae to crack eggs internally after swallowing them.

• Grayish, brownish, or tan coloration with a series of dark, roughly rectangular or zigzag blotches down the back, often causing confusion with vipers
• Slender to moderately stout body with keeled scales
• Small head barely distinct from the neck, with virtually no visible teeth
• Round pupils
• Adults typically 50-90 cm long

Often mistaken for vipers due to blotched patterning, but distinguished by its smaller head and lack of a triangular viper-shaped head.

Occurs in savanna, grassland, woodland, and scrubland across much of sub-Saharan Africa, often near areas with abundant bird nesting activity, including near human settlements.

Mostly nocturnal, actively searching out and locating bird nests by scent. Swallows eggs whole, then uses specialized bony projections from the vertebrae to puncture and crack the shell internally, regurgitating the crushed shell afterward. When threatened, it may mimic viper behavior with exaggerated coiling, hissing, and body-rubbing sounds. Reproduction is oviparous, with females laying clutches of roughly 6-25 eggs.
