Meaning and Definition
Planktonic organisms that spend only part of their life cycle (e.g., larval or juvenile stages) as plankton, eventually developing into benthic (seafloor) or nektonic (swimming) adults.
A temporary component of the plankton community, crucial for the dispersal and life cycle of many marine species. Contrasts with holoplankton (permanent plankton).

FAQ
Frequently Asked Questions
No, it is a highly specialised scientific term used almost exclusively in marine biology and oceanography.
Larval stages of crabs, lobsters, sea urchins, starfish, many types of fish eggs and larvae, and the larvae of bottom-dwelling worms and molluscs.
It is crucial for understanding marine ecosystem dynamics, food webs, population connectivity, and the life histories of commercially important species.
While the concept applies, the term is overwhelmingly used in marine and estuarine science. In limnology (freshwater science), specific larval names (e.g., 'zooplankton') are more common.
Planktonic organisms that spend only part of their life cycle (e.

Memory Aids
Mnemonic
Think: 'MERO' = PARTIAL, like a MEROmorph (a partial crystal form) or MEROcracy (rule by a part). So MEROPLANKTON are PARTIAL/TEMPORARY plankton.
Conceptual Metaphor
Plankton as a nursery: Meroplankton are the 'infants' or 'juveniles' of the sea, spending their early life adrift before settling into a more sedentary or mobile adult existence.
