Also found in: Dictionary/thesaurus, Wikipedia, Hutchinson | 0.06 sec. |
bryozoanAquatic invertebrate of the phylum Bryozoa (“moss animals”), members (called zooids) of which form colonies. Each zooid is a complete and fully organized animal. Species range in size from a one-zooid “colony” small enough (less than 0.04 in., or 1 mm, long) to live between sand particles to colonies that hang in clumps or chains as much as a 1.6 ft (0.5 m) across. The texture of colonies varies from soft and gelatinous to hard with calcium-containing skeletons. Freshwater bryozoans attach primarily to leaves, stems, and tree roots in shallow water. Marine bryozoans have a wide range of habitats, from coastal areas to great ocean depths, but are most common just below the tidemarks. Bryozoans feed by capturing plankton with their tentacles. |

Delayed effects of larval exposure to Cu in the bryozoan Watersipora subtorquata. The boulder-strewn area teemed with ancient sponges, bushlike bryozoans, and other animals that form colonies and anchor themselves permanently onto solid footings. Aphios Corporation has developed a unique collection of marine microorganisms isolated from diverse organisms and extremeophilic environments such as: marine invertebrates including bryozoans, sponges, corals, and tunicates; deep sea sediments and shallow mangrove swamps; hypersaline ponds; hydrothermal vents; marine vertebrates like fish and shark; tropical and temperate oceans; and plants including macroalgae. |
