The freshwater ostracod Dolerocypris ikeyai. Click on the image for next one in the series.

Left side view of a female Dolerocypris ikeyai. This species is about 1 to 1.2 mm in length, and lives in the runoff of springs and seeps throughout most of Japan, and South Korea. It prefers very shallow, gently flowing water on a fine substrate. Males are known from only two small Japanese islands, Yakushima and Tanegashima; elsewhere populations consist of only females.
