A common Japanese clam shrimp,
Eulimnadia braueriana Ishikawa, 1895 (Crustacea, Branchiopoda, Spinicaudata) was identified based on specimens raised from dried mud taken from a rice field before flooding in the suburbs of Zama city, Kanagawa Prefecture, central Japan. Several larvae of these clam shrimps grew to adults under laboratory conditions. In this paper, we report some life-history data of the clam shrimps based on laboratory observations. In addition, the results of an investigation into their occurrence in the rice field after flooding are reported.
