Marine Organisms Classification and Characteristics

The video introduces four marine biology terms: plankton, benthic, cecil, and nectin. Plankton are organisms that drift in the ocean, unable to swim against currents. Benthic organisms live mostly on the sea floor, like lobsters. Cecil organisms are a type of benthic organism that remain attached to surfaces, such as sea anemones. Nectin refers to strong swimmers like most fish. The video also credits an artist for providing illustrations.
