| Research Abstract |
More than 80 species of interstitial Ostracoda were recognized from the intertidal zone of Japan, including 10 species that were described as new. The analysis of DNA suggested that interstitial ostracods were derived in parallel from multiple surface dwelling taxa that are phylogenetically apart from one another, and that some evolutionary trends are recognizable for the adaptation to interstitial environments. Most interstitial ostracods are much smaller than surface dwelling ones, and this is achieved by reducing the growth ratio between molts.
