Description. Calanoids can be distinguished from other planktonic copepods by having first antennae at least half the length of the body and biramous second antennae. [ 2 ] However, their most distinctive anatomical trait is the presence of a joint between the fifth and sixth body segments. [ 3 ] The largest specimens reach 18 millimetres (0.71 ...
Isopoda is an order of crustaceans. Members of this group are called isopods and include both aquatic species, and terrestrial species such as woodlice. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration.
Harpacticoida is an order of copepods, in the subphylum Crustacea.This order comprises 463 genera and about 3,000 species; its members are benthic copepods found throughout the world in the marine environment (most families) and in fresh water (essentially the Ameiridae, Parastenocarididae and the Canthocamptidae).
Dinoflagellate. The dinoflagellates (from Ancient Greek δῖνος (dînos) 'whirling' and Latin flagellum 'whip, scourge') are a monophyletic group of single-celled eukaryotes constituting the phylum Dinoflagellata[ 5 ] and are usually considered protists. Dinoflagellates are mostly marine plankton, but they are also common in freshwater ...
