Copepoda

Co·pep·o·da

(kō-pep'ō-dă),
An order of abundant, free-living, freshwater and marine crustaceans of basic importance in the aquatic food chain in both the marine and freshwater environments; some species are commonly called water fleas. Some are ectoparasites of both cold-blooded and warm-blooded aquatic vertebrates; the parasitic copepods of fish and whales are often highly modified for deep penetration of the skin or for adherence by suckers and hooks (for example, the fish lice, Argulus). Certain copepods (Cyclops, Diaptomus) are important as intermediate hosts of the tapeworm Diphyllobothrium latum and of the nematode Dracunculus medinensis.
[G. kōpē, an oar, + pous (pod-), a foot]

In their study of the structure of the parasitic fauna of the white catfish Netuma barba (Ariidae), a demersal fish that occurs in marine and estuarine environments and seeks the mouths of rivers and lagoon areas at spawning time, Tavares and Luque (2004) found that Copepoda was the most abundant taxon, representing 37.
Copepoda and Acari with 6 and 9 taxa respectively were the next most important groups, but they did not exceed 3 and 6% of total relative abundance, respectively.
The fish consumed 27 food items, grouped into seven food categories: vegetal matter (leaves, roots, stalk and seeds), algae (Bacillariophyceae, Chlorophyceae, Cyanophyceae, Euglenophyceae, Oedogoniaceae, Zygnemaphyceae), detritus (organic and inorganic matter), fish (remains, scales, eggs and fingerlings), microcrustaceans (Cladocera, Copepoda, Rotifera, Ostracoda), macroinvertebrates (Hirudinea and Oligochaeta) and aquatic insects (Diptera and Coleoptera).
