Definition of plankton in English: planktonnoun ˈplaŋ(k)tɒnˈplaŋ(k)t(ə)nˈplæŋktən mass nounThe small and microscopic organisms drifting or floating in the sea or fresh water, consisting chiefly of diatoms, protozoans, small crustaceans, and the eggs and larval stages of larger animals. Many animals are adapted to feed on plankton, especially by filtering the water. prawns change their diet from plant plankton to animal plankton Compare with nekton as modifier plankton feeders Example sentencesExamples - The plankton that permeates these waters attracts vast swarms of anchovies, which in turn draw millions of seabirds.
- Each oyster feeds naturally on plankton brought in on the tide until the time comes for them to be lifted, washed and packed.
- Manta rays live in tropical waters and feed on plankton, using their frontal flaps.
- They have no teeth, and feed by ‘hoovering up’ tiny plankton from the sea.
- Smaller warm water plankton has replaced them and they are less nutritious, according to the scientists.
- The expedition also found rings of plankton organisms that measured 10 km wide.
- Whales eat big fish, which eat medium fish, which eat small fish, which eat smaller fish, which eat plankton.
- However, the seaweeds or the algae and in particularly the microscopic plankton can fix a lot more carbon than a forest can.
- These regions of high productivity promote the development of plankton, which feeds planktivorous fish such as anchovies.
- All plankton, kelp forests and seagrass beds are found in the euphotic zone.
- The fish then turn to feeding on larger plankton, including small fish, before migrating down into the depths at around two years of age.
- The dung feeds microscopic plankton, which are consumed by worms and larvae.
- Microscopic plankton trapped in the finely tipped gills are pulled slowly into waiting mouths.
- The young remain in the water column feeding on plankton until they are around 50 mm in length.
- They may also forage for insects, plankton, mollusks, crustaceans, and small fish.
- Every March and April, whale sharks come to Ningaloo Reef on Australia's outback coast to feed on plankton.
- In the newly exposed waters and throughout the North Atlantic Ocean, plankton growth is prodigious.
- The eggs and young, which hatch in around two weeks, drift in the Oceans currents feeding upon plankton for the first few months of their life.
- The production of plankton is directly related to the fertility of the water.
- Scientists say that the change in species of plankton, from cold water types to warm water, are less favourable to cod in its juvenile stage.
- The significance of this is that other species such as shellfish and crustaceans feeding in plankton could be affected.
Derivatives adjective ˈplaŋ(k)tɪkˈplæŋktɪk Biology Relating to or found in plankton. Example sentencesExamples - a diverse planktic fauna
- Stable isotopic analyses were conducted on monospecific planktic and benthic foraminifera.
- Questions arose as to whether cyclocystoids were benthic or planktic, sessile or free living.
- The younger planktic faunas are typical of the temperate conditions and depths from which the samples were collected.
adjective plaŋ(k)ˈtɒnɪkplæŋkˈtɑnɪk The depth is recognized as that of the lower photic zone, the reproductive depth for planktonic foraminifera. Example sentencesExamples - They get their nutrition from planktonic organisms brought in on the sluggish tides where the caves connect with the ocean.
- As the eggs hatch, the larvae find themselves immersed in a bath of food: the water is bursting with millions of planktonic organisms.
- The marine life benefits from planktonic nutrients, which means the area is teeming with both Mediterranean and Atlantic species.
- This bacterial strategy is reasonable, since the above-mentioned advantage would be lost if the planktonic cell had peritrichous flagella.
Origin Late 19th century: from German, from Greek planktos 'wandering', from the base of plazein 'wander'. planet from Middle English: Early Greek astronomers observed certain heavenly bodies moving around the night sky in contrast to the stars, which stayed permanently in a fixed position in relation to one another. This is why they are called planets, from Greek planētēs ‘wanderer’. The Sun and the Moon were once thought of as planets too. Plankton, the term for small and microscopic organisms floating in the sea, comes via German from the related Greek word planktos, ‘wandering or drifting’. See also aeroplane
