Jellyfish eat the eggs and larvae of other species higher on the food chain, as well as the plankton that those larvae would eat.
plankton, those wily producers of every second breath of oxygen you breath, will be naked and vulnerable.
By autumn, plankton concentrations diminish as light and nutrient levels decrease.
Many of the luminous marine animals are to be found in the plankton, while the littoral luminous forms are in the minority.
The plankton (small floating animals) is distributed in the morning, other animals as required.
Both fish and plankton are consumed by humpback whales as well as by other predators.
The animals of the open sea are conveniently divided into the active swimmers (Nekton) and the more passive drifters (plankton).
Hunger is often very much in evidence in the open sea, especially in areas where the plankton is poor.
The same method is followed by the pretty radiolaria which live floating (as plankton) at various depths of the sea.
The Crustacea of the plankton never carry the heavy armour found in bottom-living species.
1891, from German Plankton (1887), coined by German physiologist Viktor Hensen (1835-1924) from Greek plankton, neuter of planktos "wandering, drifting," verbal adjective from plazesthai "to wander, drift," from plazein "to drive astray," from PIE root *plak- (2) "to strike, hit" (see plague (n.)). Related: Planktonic.
Small organisms that float or drift in great numbers in bodies of salt or fresh water. Plankton is a primary food source for many animals, and consists of bacteria, protozoans, certain algae, cnidarians, tiny crustaceans such as copepods, and many other organisms. Compare benthos, nekton.
