MARINE VOCABULARY adaptation - a distinct feature of an organism that allows it to survive more easily in its environment alga(e) - a simple plant, without a true stem, leaves, or roots, and possessing chlorophyll; includes almost all seagrasses amphipod - one of an order (Amphipoda) of elongate and usually laterally compressed crustaceans. The species live in a variety of habitats from the parasitic state to the deep pelagic. arthropod - one of a phylum (Arthropoda) of animals with segmented external skeletons and jointed appendages; for example, the crustaceans, spiders, and insects autotroph - an organism capable of synthesizing its organic nutrients directly from the sunlight energy or from inorganic nutrients; also called primary producer. It includes the plants, phytoplankton, and some bacteria. Opposed to heterotroph, which is an organism that is unable to synthesize its own food and must use other organisms for nourishment. benthic - referring to the bottom of a body of water ( i. e. the sea floor) benthos - the aggregation of organisms living on or at the bottom of a body of water biotic factors - biological factors, such as availability of food, competition between species, and predator- prey relationships, that affect the distribution and abundance of a given species of plant or animal bloom - a rapid and often unpredictable growth of a particular species in an ecosystem buoyancy - the tendency of an object to rise or float. The plankton remain buoyant by several means: body projections or appendages to increase their surface area and frictional drag, air or oil bubbles trapped in their bodies, the exclusion of higher-density ions and their replacement with less-dense ions, and porous and less- weighed skeletons. carnivore - an animal that eats other animals for food cilia - tiny, hair-like projections used for locomotion in some protozoans. One of the best known groups of marine ciliate protozoans is the tintinnids. community - an assemblage of interacting plants and animals forming an identifiable group within a biome, as in salt marshes or coral reef communities consumer - herbivores and carnivores that consume energy originally transformed into food by the primary producers copepod - one of a subclass (Copepoda) of minute shrimp-like crustaceans; most species range from about 0.5 to 10.0 mm in length crustacean - one of a class (Crustacea) of arthropods that breathe through gills or branchiae and have a body commonly covered by a hard shell or crust. The group includes barnacles, crabs, shrimps, and lobsters. decapod
