Origin of planktonGerman from Classical Greek planktos, wandering from plazesthai, to wander, akin to planan: see planet
Small crustaceans in the Atlantic ocean, along with eggs, larvae and protozoans are an example of plankton.
Origin of planktonGerman from Greek neuter of planktos wandering from plazein to turn aside ; see plāk-2 in Indo-European roots.
(usually uncountable, plural planktons)
From German Plankton, coined by Viktor Hensen and derived from Ancient Greek Ï€Î»Î±Î³ÎºÏ„ÏŒÏ‚ (planktos, “drifter").
- It is on the plankton that a great part of the higher animal life of the sea ultimately depends for food.
- All forms of plankton are more abundant in the shallow coastal waters of relatively low salinity.
- Therefore the animal organisms, as a rule, reproduce in the spring or early summer just after the vernal phyto-plankton maximum.
- The organisms constituting this plankton are mostly unicellular, of ten aggregated together in colonies, and the remarkable structure which they exhibit has added a new chapter to the story of adaptation to environment.
- Depths greater than 2500 fathoms. Viewed as a whole this deposit may be taken as a partial precipitation of the plankton living in the upper waters of the open sea.
