Cyclops (genus)
:''This article is about the crustacean. See Cyclops (disambiguation) for other meanings.''
''Cyclops'' is one of the most common genera of freshwater copepods, comprising over 400 species .〔〔
〕 Together with other similar-sized non-copepod fresh-water crustaceans, especially cladocera, they are commonly called water fleas. The name ''Cyclops'' comes from the Cyclops of Greek mythology which shares the quality of having a single large eye, which may be either red or black in ''Cyclops''.
== Anatomy ==
''Cyclops'' individuals may range from ½–5 mm long and are clearly divided into two sections. The broadly oval front section comprises the head and the first five thoracic segments. The hind part is considerably slimmer and is made up of the sixth thoracic segment and the four legless pleonic segments. Two caudal appendages project from the rear. Although they may be difficult to observe, ''Cyclops'' has 5 pairs of legs. The long first antennae, 2 in number, are used by the males for gripping the females during mating. Afterwards, the female carries the eggs in two small sacs on her body. The larvae, or nauplii, are free-swimming and unsegmented.
