It has been known that many organisms evolved to survive in temporary or ephemeral inland waters. Many of them have dry-resistant eggs against desiccation. The structural feature of egg shell is important because only this will ensure to survive the dry period. Structural features of egg shell in the parthenoge-netic Heterocypris incongruens (Ramdohr, 1808) was investigated by scanning electron microscope. Results showed that egg shell structure consists of two distinct layers; an outer layer with holes or alveoli and an inner layer consisting of two dense sublayers. Also, structural similarities in egg-shell of H. incongruens and some other crustaceans which combat desiccation problem will be discussed.
