	Calanus Marshallae ''Calanus marshallae'' is a species of copepod which forms part of the zooplankton in the northern Atlantic Ocean and the northern Pacific Ocean. Taxonomy Several species of copepod in the genus ''Calanus'' tend to dominate the zooplankton Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by ... of the northern oceans; ''Calanus finmarchicus'' is the best known species, but historically there was little to distinguish it from other closely related species. Analysis in 1974 by the American marine biologist B.W. Frost of specimens gathered throughout the northern Atlantic and Pacific Oceans, and the Arctic Ocean, showed that there are three species present; ''C. finmarchicus'', ''Calanus glacialis, C. glacialis'' and a new species, ''C. marshallae''.

	Calanus Finmarchicus ''Calanus finmarchicus'' is a species of copepods and a part of zooplankton, which is found in enormous amounts in the northern Atlantic Ocean. Distribution and ecology ''Calanus finmarchicus'' is most commonly found in the North Sea and the Norwegian Sea. It is also found throughout the colder waters of the North Atlantic, especially off the coast of Canada, in the Gulf of Maine, and all the way up to western and northern Svalbard. ''Calanus finmarchicus'' is one of the most commonly found species of zooplankton in the subarctic waters of the North Atlantic. Sometimes confused with '' C. helgolandicus'' and '' C. glacialis'', ''C. finmarchicus'' is a large planktonic copepod whose chief diet includes diatoms, dinoflagellates, and other microplanktonic organisms. In fact, some studies have shown that heterotrophic microplankton provide a "prey resource sufficient for net lipid synthesis as well as egg production".
