What animal only eats eggs?

The animal that primarily eats eggs is the egg-eating snake, specifically from the genus Dasypeltis. These snakes have specialized adaptations that allow them to consume eggs whole, including a flexible jaw and the ability to digest the egg's shell. Other animals that predominantly eat eggs include certain birds, such as the cassowary, and some species of reptiles and mammals, like the echidna. However, the egg-eating snake is particularly notable for its exclusive diet of eggs.
