WebTwo co-occurring high altitude calanoid copepods, Diaptomus shoshone Marsh and D. coloradensis Forbes are of different size: the former is approximately twice as long as the latter. There are also temporal differences in development: the former matures 2-3 weeks before the latter in most ponds. Gut analyses of copepodids and adults of both species Diaptomus is a genus of copepods with a single eye spot. It is superficially similar in size and appearance to Cyclops. However it has characteristically very long first antennae that exceed the body length. In addition, the females carry the eggs in a single sac rather than the twin sacs seen in Cyclops. It is a copepod of larger freshwater ponds, lakes and still waters.
