F EEDING TECHNIQUES OF CALANOID COPEPODS The traditional view of planktonic calanoid copepods as relatively mechanical suspension- feeders has been replaced by the recognition that a wide variety of mechanisms exist to detect, pursue, capture and reject prey (Price 1988).
Calanoid copepods play an important role in aquatic food webs, particularly in more oligotrophic systems, as either primary consumers or predators. They are also an important source of food for larval, juvenile, and adult fish of many species.
Calanoid copepods are extremely successful inhabitants of marine, brackish and freshwater plankton. Morphological data are used to arrive at a first, parsimony-based phylogeny for the calanoid.
Calanoid copepods play an important role in the pelagic ecosystem making them subject to various taxonomic and ecological studies, as well as indicators for detecting changes in the marine habitat.
The central theme of the conference was the biology of marine planktonic copepods, although the scientific programme was extremely varied reflecting the wide range of life styles adopted by copepods. The three invited symposia held during the conference focussed attention on particular topical areas of research within the field of marine plankton, and also provided reviews of chosen aspects of.
Calanoid copepods are characterized by their long antennae, which are at least half the length of their torpedo shaped body. Typically, calanoids have a body length of 0.5 to 2.0mm, however species as large as 18.0mm and as small as 0.25mm have been measured. Compared to other copepod orders, the overall morphology of calanoids is uniform; a.

On the diets of calanoid copepods G. S. Kleppel Nova University Oceanographic Center, 8000 North Ocean Drive, Dania, Florida 33004, USA ABSTRACT: A review of the literature (ca 1900 to 1992) on copepod feeding indicates that combinations of stochashc and deterministic processes result in behaviors, or feeding strategies, that.
CALANOIDA Sars, 1903 (calanoid copepods) CALANOIDA (calanoid copepods) may be included in 'fed on by' relations listed under the following higher taxa.
Calanoida: Description. Includes 43 families and approximately 2000 species (marine and freshwater). Distinguishing characteristics. Long, usually slender body. Long antennules. Geniculate antenna e in males. Gymnoplean tagmosis (boundary between fifth pedigerous somite and genital somite).
Copepods are common in a variety of aquatic and semiaquatic habitats ranging from moist soils, leaf packs, groundwater, wetlands, and phytotelmata, to lakes, rivers, estuaries, and open oceans. Most species are omnivorous to some extent, with foods ranging from detritus and pollen, to phytoplankton, other invertebrates, and even larval fish.
