[[File:Diaptomus EPA.jpg|thumb|right|Unidentified species of ''Diaptomus'' from the [Great Lakes](/source/Great_Lakes)]]
'''''Diaptomus''''' is a [genus](/source/genus) of [copepod](/source/copepod)s with a single eye spot. It is superficially similar in size and appearance to [''Cyclops''](/source/Cyclops_(genus)). However it has characteristically very long first [antennae](/source/antenna_(biology)) 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](/source/fresh_water) ponds, lakes and still waters.

==Species==
''Diaptomus'' contains more than 60 species; many species formerly included in ''Diaptomus'' are now in separate genera such as ''[Aglaodiaptomus](/source/Aglaodiaptomus)'' and ''[Notodiaptomus](/source/Notodiaptomus)''.<ref>{{cite web |year=2009 |title=''Diaptomus'' Westwood, 1836 |editor=T.
