Definition of nekton in English:
Aquatic animals that are able to swim and move independently of water currents. Often contrasted with plankton.
- On average, collections were made every 3-4 d for phytoplankton and zoo-plankton, 7 d for benthos, and 10-14 d for nekton (fish and swimming benthic invertebrates).
- This may have made it the most easily accessible prey for predators in the nekton, such as fishes.
- It is the region inhabited by plankton, which are minute organisms that drift or float at various depths in the water, and by nekton, which are free-swimming organisms.
- Example sentences
- Sponges, corals, bryozoa, gastropods, bivalves, and ammonoid and belemnite cephalopods all flourished, the latter two groups becoming the dominant nektonic invertebrates for the rest of the Mesozoic.
- In fact, cephalopods themselves were the only Ordovician nektonic durophagous predators.
- This shows on one hand a strong correspondence of nektonic life with sea level changes and, on the other, the strong interrelationship (competitive and/or predatory) of the nektonic biota.
