Cyclops bicuspidatus is a planktonic species of copepod found throughout the world, except Australia, [4] and characteristic of the Great Lakes of North America. [5] It is a deep water species found throughout the year with peak abundance occurring in May or June. [5]
Zooplankton (/ ˈ z oʊ. ə p l æ ŋ k t ən /; [2] / ˌ z oʊ. ə ˈ p l æ ŋ k t ən /) [3] are heterotrophic (sometimes detritivorous) plankton. The word zooplankton is derived from Ancient Greek : ζῷον , romanized : zôion , lit.
Part of the contents of one dip of a hand net.The image contains diverse planktonic organisms, ranging from photosynthetic cyanobacteria and diatoms to many different types of zooplankton, including both holoplankton (permanent residents of the plankton) and meroplankton (temporary residents of the plankton, e.g., fish eggs, crab larvae, worm larvae).
Many zooplankton are tiny animals found with the phytoplankton in oceanic surface waters, and include tiny crustaceans, and fish larvae and fry (recently hatched fish). Most zooplankton are filter feeders, and they use appendages to strain the phytoplankton in the water. Some larger zooplankton also feed on smaller zooplankton.
Invoking images of the open ocean's surface, the imagination can conjure up an endless empty space. A flat line parting the blue below from the blue above. But in reality a diverse array of species occupy this unique boundary layer. A tangle of terms exist for different organisms occupying different niches of the ocean's surface.
Calanoida is an order of copepods, a group of arthropods commonly found as zooplankton. The order includes around 46 families with about 1800 species of both marine and freshwater copepods between them. [2]
Zooplankton: Called nonconstitutive mixotrophs by Mitra et al., 2016. [40] Zooplankton that are photosynthetic: microzooplankton or metazoan zooplankton that acquire phototrophy through chloroplast retention a or maintenance of algal endosymbionts. Generalists Protists that retain chloroplasts and rarely other organelles from many algal taxa
Zooplankton are partially responsible for the active energy flux between superficial and deep layers of the ocean. [ 25 ] [ 26 ] [ 27 ] Zooplankton species composition , biomass, and secondary production influence a wide range of trophic levels in marine communities, as they constitute a link between primary production and secondary consumers.
