plankto-, plankt-, -plankton

(Greek: passively drifting, wandering, or roaming)

hypoplanktonic
ichthyoplankton
1. Fish that maintain their position or distribution as a result of the movement of water.
2. Floating new born fish before they can adequately swim by themselves.
isoplankt
Line representing, on a map, distribution of equal amounts of plankton, or of particular plankton species.
kalloplankton
Organisms supported by gelatinous cases.
knephoplankton
Plankton that occurs between 15 fathoms and 250 fathoms.
kremastoplankton
Plankton that consists primarily of organs floating with the aid of hairs, bristles, etc.
limnoplankton
Plankton found in fresh water and in marshes.
macrophytoplankton
Composed either of large plants (megaphytoplankton) or of elongate plants such as filamentous algae.
macroplankton
Large planktonic organisms 20-200 mm in diameter or those that can be classified without the need of a microscope.
megaloplankton
Largest of the planktonic organisms, typically greater than 10 mm in diameter.
megaplankton
Planktonic organisms of the largest size group, 200 mm to 2 m (including water-hyacinth, jellyfish, etc.).
meroplankton
1. Organisms in marine coastal areas that spend only part of their life cycle as plankton, being at other times benthic dwellers.
2. Passing only part of the life-cycle drifting or swimming weakly in water.
meroplanktonic
mesoplankton
1. The plankton living between about a hundred fathoms from the bottom and a hundred from the surface or between epiplankton and bathyplankton; alternatively, all plankton below the epiplankton level.
2. A classification of plankton of intermediate body size, between macroplanktons (large planktons) and microplanktons (very-small planktons).
mesoplanktonic
