African egg-eating snakes raid nests for bird eggs, which they swallow whole with their unhingeable jaws. Lacking traditional teeth, these “soft-mouthed serpents” have knobby protuberances along their backbones. Once the egg is swallowed, these “spinal teeth” will break it open in a sawing motion as they pass it toward the stomach. The traits are truly bizarre, but fortunately, there is no human danger from these snakes.
