What is another word for planktonic?
Pronunciation: [plaŋktˈɒnɪk] (IPA) 
Planktonic refers to organisms that are free-floating in water and cannot swim against currents, such as algae, diatoms, and microscopic animals. Some synonyms for the word "planktonic" include "pelagic," "floating," "drifting," and "passive." Pelagic refers to organisms that live in the open sea or ocean, and is often used in contrast to benthic, which refers to organisms that live on or in the bottom of the sea or ocean. Floating and drifting both describe the movement of planktonic organisms, implying that they are carried along by the water rather than actively swimming. Passive also describes the lack of movement in planktonic organisms, indicating that they are at the mercy of the currents.
