Welcome to the website of the World Association of Copepodologists !

Copepods are among the most abundant metazoans on Earth and can be found almost everywhere there is water - from high-altitude lakes in mountain ranges, down to the depths of the ocean trenches. Copepods dominate the zooplankton, they are super-abundant in sediments, and they are parasitic on virtually every phylum of animals from sponges to chordates (including reptiles and mammals).


This website will help you find out more about this fascinating group of crustaceans.


The World Association of Copepodologists (WAC) is a nonprofit international organization whose purpose is to promote research on Copepoda by facilitating communication among interested specialists. Join WAC today!

The business of the WAC is conducted primarily at a triennial business meeting held during each International Conference on Copepoda (ICOC). Since 1987, the ICOC has been held at venues in Asia, Africa, North and South America, and Europe. The most recent (13th) ICOC was held in Los Angeles, U.S.A. in July 2017. This conference was organized by Julianne Kalman Passarelli at Cabrillo Marine Aquarium (julianne.passarelli@lacity.org).
