The freshwater ostracod Uncinocythere occidentalis. Click on the image for next one in the series.

A couple of Uncinocythere occidentalis, male on top, recovered from a signal crayfish. This group lives on the bodies of other crustaceans, typically crayfish. The males attach themselves to juvenile females using a special hook on the male sexual organs and the antennae. They wait until the female molts and becomes sexually mature before fertilizing the females. Both the signal crayfish and this species of ostracod are invasive species in Japan, originally from North America. (Click on the image to view the next one in the series.)
