Copepod ( Kope = Greek for "oar"    Podos = Greek for "foot")
Hence Copepod = oar-footed, referring to the pair of swimming legs on the same somite that are moved together, like the oars of a sculling shell

What is a copepod?

These aquatic crustaceans are very diverse and are the most numerous metazoans in the water community ("metazoan" means all multi-celled animals).  Copepod habitats range from fresh water to hypersaline conditions, from subterranean caves to water collected in bromeliad leaves or leaf litter on the ground and from streams, rivers, and lakes to the sediment layer in the open ocean.  Their habitats also range from the highest mountains to the deepest ocean trenches, and from the cold polar ice-water interface to the hot active hydrothermal vents.  Copepods may be free-living, symbiotic, or internal or external parasites on almost every phylum of animals in water.  The usual length of adults is 1-2 mm, but adults of some species may be as short as 0.2mm and others may be as long as 10mm. 

Ecologically they are important links in the food chain linking microscopic algal cells to juvenile fish to whales. Copepods also have the potential to act as control mechanisms for malaria by consuming mosquito larvae, and contrariwise are intermediate hosts of many human and animal parasites.

Branchiura (commonly referred to as sea lice) are also included with the Copepoda, since many copepod researchers also study these parasites of fish.

THE WILSON COPEPOD LIBRARY

The bibliographic database was developed and is maintained by staff of the C.B. Wilson Copepod Library, and contains all the known literature for copepods and branchiurans.  Currently, over 44,700 bibliographic enteries on copespods are in the database. Current staff organizing the day to day operations of this Library are T. Chad Walter, Frank D. Ferrari, and Lana Ong.   Janet Reid also provides significant input into this web site. We gratefully accept donations of literature on all aspects of the Copepoda, and request that you send us a copy of all your future publications. Also check Researchers page and see if your data is correct and send us any updates.
