plankto-, plankt-, -plankton

(Greek: passively drifting, wandering, or roaming)

Consisting mainly of filamentous algae.
tychoplankton (s) (noun), tychoplanktons (pl)
1. Aquatic entities occasionally carried into plankton (very small plants and animals) by unexpected factors; such as, by a violent movements of air or heavy moisture: When Susan and the other botany students analyzed the plant masses off the shore of the lake, they discovered that a lot of tychoplankton had been swept into the plankton probably as the result of strong winds and water turbulence.
2. Planktonic forms, particularly algae, that become inadvertently entangled among mats of vegetation near the shore: Bill and Jane noticed a mass of tychoplankton entangled in the seaweed on the beach of the ocean.
Another term for nanoplankton (very tiny plankton).
zooplankter (s) (noun), zooplankters (pl)
A collective term for the wide variety of microscopic animal organisms that float or drift freely in water because they have little or no ability to determine their own movement: "Zooplankters are found worldwide in both aquatic or marine environments and they represent the basic level of many feeding relationships in the oceans."
zooplanktology (s) (noun), zooplanktologies (pl)
The biological study of tiny creatures that exist in oceans, etc.
zooplankton (noun) (singular and plural)
1. Floating animal organisms collectively: "Tiny animals, or zooplankton, consist of rotifers, copepods, and krill or microorganisms once classified as animals; such as, dinoflagellates and other protozoans."
2. A small animal organism present in natural waters: "The majority of zooplankton are small crustaceans (copepods, krill), arrowworms, and gelatinous creatures that feed primarily on phytoplankton."
3. Microscopic animals that move passively in aquatic ecosystems; such as, protozoans: "To the zooplankton belong the protozoa, the sea anemones, the corals, and the incredibly shaped jellyfishes."
4. Microscopic drifting animal life much of which lives on or near the surface of water but some are at greater depths: "The zoologist was studying the nutritional requirements and efficiencies of food conversion of marine animals (zooplankters) feeding on marine phytoplankters or on other small animals."
zooplanktonic (adjective), more zooplanktonic, most zooplanktonic
Pertaining to animals that float in aquatic environments; such as oceans: "Zooplanktonic creatures are kept in suspension by water turbulence and dispersed more by such water movements than by their own efforts."
