Is a jellyfish a plankton or Nekton?

Organisms such as jellyfish and others are considered plankton when they are very small and swim at low Reynolds numbers and considered nekton as they grow large enough to swim at high Reynolds numbers.

Are all jellyfish planktonic?

All jellyfish are gelatinous zooplankton but not all gelatinous zooplankton are jellyfish. The most commonly encountered organisms include ctenophores medusae salps and Chaetognatha in coastal waters.

What makes something considered plankton?

What is the importance of zooplankton?

The zooplankton community is an important element of the aquatic food chain. These organisms serve as an intermediary species in the food chain transferring energy from planktonic algae (primary producers) to the larger invertebrate predators and fish who in turn feed on them.

Are Siphonophores zooplankton?

Siphonophores are gelatinous planktonic organisms – relatives of jellyfish anemones and corals in the family of cnidarians. Like corals siphonophores form colonies. … These arms bring food to giant mouths and stomach organs that swallow and digest prey nourishing the entire colony through the stolon.

What kind of sea creature is plankton?
