Freshwater Copepods

Posted by Scott Collins (Ontario, California, United States) on 3 February 2008 in Animal & Insect and Portfolio.

The guys are about half the size of a grain of rice, and are like small clams except there is a crab-like creature inside. They feed on algae in rivers and lakes, and these were in with some of my freshwater fish. I used a 100 power microscope and a Sony Cybershot to photograph them, with oblique lighting.
