Abstract

The most important evolutional gain of some non-marine ostracods are dry- resistant eggs. The “pause- wait” is carried out until suitable conditions are developed during the evolution of dry-resistant eggs. Through the egg-resting period, survival of ostracod individuals depends on a temporary water body. In this paper, we investigated Cypris pubera O.F. Müller, 1776, eggs via Scanning Electron Microscope (SEM). We observed two different types of eggs in the life cycle of one specimen. The subitaneous egg type of the C. pubera is shown first time here. Subitaneous egg can be only seen in first laying period which explains its role in the growth stage during the C. pubera life cycle.
