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]

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.
Calanoid copepods are the dominant animals in the plankton in many parts of the world's oceans, making up 55–95% of plankton samples. [2] They are therefore important in many food webs, taking in energy from phytoplankton and algae and 'repackaging' it for consumption by higher trophic level predators. [ 2 ]
Daphnia species are prey for a variety of both vertebrate and invertebrate predators. The role of predation on D. pulex population ecology is extensively studied, and has been shown to be a major axis of variation in shaping population dynamics [9] and landscape-level distribution. [10]

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.
