A large class of small aquatic crustaceans, many of which occur in plankton and some of which are parasitic on larger aquatic animals.‘Hemoglobins have been described in a select number of crustacean groups, including the Branchiopoda, Ostracoda, Copepoda, Cirrepedia, and Decapoda.’
- ‘However, cladistic analysis indicates that the Cycloidea possibly belong within the Crustacea as a sister group of the Copepoda.’
- ‘The Copepoda are an incredibly numerous group of crustaceans.’
- ‘Monstrilloid copepods represent one of the ten orders of Copepoda currently recognized.’
- ‘In insects the Orthoptera (especially grasshoppers), and in crustaceans the Decapoda (especially caridean shrimps), Stomatopoda (mantis shrimps) and calanoid Copepoda, are the only groups to far exceed a typically small range.’
Modern Latin, from Greek kōpē ‘handle, oar’ + pous, pod- ‘foot’ (because of its paddle-like feet).
