Amniotic Egg

Davie-20130823-00085

 

The chicken egg above is an example of an amniotic egg. Basically, any egg is considered an amniotic egg if the vertebrate within the egg contains an amnion during embryonic development. Animals that have amnions during embryonic development include reptiles, birds, and mammals. The amnios are an adaptation for the animals to lay eggs on land and not get damaged rather than those that lay eggs in water known as anamniotes (lacking amniotes).
