This egg-eating snake is one of 18 species that belong to the genus
Dasypeltis
, found in Africa. They feed exclusively on bird eggs and devour them whole. Once a snake has gotten its jaws around an egg, it crushes it to extract the contents. This is done by vertical spines along the serpent’s vertebrae, which extend into its oesophagus and puncture the shell when the snake squeezes its muscles.
