Scanning electron microscope studies of the egg shell in some anostraca (Crustacea: Branchiopoda).

摘要: The tertiary shell of the eggs anostracan crustaceans consists two layers, an outer cortex and inner alveolar layer. Scanning electron microscope studies show that, in most species, these layers are separated by a subcortical space which intercommunicates with spaces meshwork No evidence was found for direct communication between pores on surface Branchipus stagnalis space. were Branchinecta packardi, Chirocephalus diaphanus, Anemia salina, nor notostracan Triops cancriformis. Similarities structure possible functions egg shells certain insects discussed relation to similarities features their environments.
