Common Egg-Eating Snake Fact File

Appearance

The common egg-eating snake is one of five species of egg-eating snake in Africa. They have a long, slender body which is grey or reddish-brown in color. This is patterned with darker, angular patterns.

Their head ends with a rounded snout. It is highly flexible to allow the snake to swallow eggs, their main food source.

Due to their diet of eggs they are one of the few snakes which do not have any teeth.

Their body measures between 50 and 90cm (20-36in) long. This species has a maximum weight of 0.5kg (1lb).

Diet

The common egg-eating snake feeds exclusively on eggs. These may be up to three times the size of their head.

As such they ingest a large quantity of food during the breeding season of birds and fast for the remainder of the year.

Snakes test eggs with their tongue to determine that they are fresh as they can not digest rotten eggs or bird fetuses.

Once the egg is inside their mouth they pierce it with the tooth like structures at the back of their mouth.

Only the egg white and yolk is digested while the shell is crushed up and regurgitated as it cannot be digested.
