The first envelope – the one in contact with the membrane of the egg – is made of glycoproteins and is known as the vitelline membrane (zona pellucida in mammals).
Larval dispersal is one of the most important topics in marine ecology, today.Many marine invertebrates and many fishes have a bi-phasic life cycle with a pelagic larva or pelagic eggs that can be transported over long distances, and a demersal or benthic adult. [1]
The only living mammals that lay eggs are echidnas and platypuses.
