Meroplankton Part I Introduction: Plankton are drifters. These organisms may have some movement, but are pushed around by currents. They may be classified either as holoplankton or meroplankton. Holoplankton spend their entire lifecycle as plankton, where as meroplankton spend only part of their lifecycle as plankton. An example of meroplankton is squid. After it hatches from an egg, the young squid are initially drifters, but eventually grow to where they become nekton, animals that can actively swim against a current. Activity: Place the animals in the categories: holoplankton, meroplankton, or nekton. Meroplankton are subdivided into benthic, those that settle on the bottom; demersal, those that swim near or above the bottom; and pelagic, the open ocean swimmers. Nekton refers to the swimmers, but in this case list just the animals that are born or hatch as nekton only. Do note that it is not always easy to place an organism in one exclusive group. There may be some exceptions. Catagories: Holoplankton Meroplankton Benthic Demersal Pelagic Nekton
