The word zooplankton is derived from Ancient Greek: ζῷον, romanized: zôion, lit. 'animal'; and πλᾰγκτός, planktós, 'wanderer; drifter'. [4] Zooplankton is a categorization spanning a range of organism sizes including small protozoans and large metazoans.

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.
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
Jellyfish are slow swimmers, and most species form part of the plankton. Traditionally jellyfish have been viewed as trophic dead ends, minor players in the marine food web, gelatinous organisms with a body plan largely based on water that offers little nutritional value or interest for other organisms apart from a few specialised predators such as the ocean sunfish and the leatherback sea turtle.
Other studies have found high concentrations of plastics in the area in which zooplankton accumulate, and these anthropogenic particles may resemble zooplankton and thus be taken up by animals ...
Zooplankton are tiny animals suspended in the water column. Like phytoplankton, these species have developed mechanisms that keep them from sinking to deeper waters, including drag-inducing body forms, and the active flicking of appendages (such as antennae or spines). [1]
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.
