Abstract: Despite of the significance of three amphidromous atyd shrimp, Caridina typus, C. serratirostris, and C. leucosticta in coastal ecosystem in southwest Japan, their early life history have not been clarified. Because the morphological characteristics have not been described to these up to now, the early life history in the sea area is hardly researched. The Zoea larva of three species Co. typus, 0. serratirostris, and C. leucosticta) was bred in this research. and the form at the larval stage was described. In the number of Zoeal instal's, C. typus was 9, C. serratirostris was 9, and C. leucosticta was 7. The larval developmental patterns of C. typus and C. serratirostris were almost the same. The number and duration of zoeal instal's of C. leucosticta was smaller and shorter than the two other species. Zoeal inster has a different possibility the larva bred under the condition in this study is the same genus. However, the difference was seen. and the problem was left for the breeding condition etc. in the number of periods.
