Kenya. An Egg-eating snake engulfing a quale egg in a matter of seconds. These Egg-eaters are among some of the most harmless snakes in the world as they have no teeth whatsoever as their only diet is eggs. These snakes have a very unique way of eating and digesting their food. Egg eaters will go into bird nests and find eggs. Once they have eaten an egg the snake uses a serrated edge on their spine to break the shell. Once the nutrients is ingested the snake regurgitates the egg shell in a compressed pellet shape. Orange snake in the tree branch swallows the white egg whole.
