Two zooids of an bryozoan (phylum Entoprocta) colony; ...Bryozoans are small invertebrates that expand from a party of one to a colony of thousands, which might encrust an entire kelp blade. The individual bryozoan — called a zooid — lives within a box-shaped compartment made of calcium carbonate and chitin, a material found in crab shells. Zooids are tiny, perhaps no taller than 1/32 of an inch. The colony grows and expands by budding new zooids from parental tissues. If a piece of bryozoan colony breaks off, the part (with at least one living zooid) drifts in the current until it encounters a solid object, to which the zooid may adhere. If conditions permit, zooid will continue to grow by creating buds and establishes a new colony.The first of two volumes describing Australia's 1200 known species of bryozoans.

Copper sulfate comes in several forms depending on how finely it is ground. Bryozoan colony attached to a rock in the Baudette River. Each fall the bryozoans begin to die off, but create overwintering "eggs" that will form new colonies the next year. When the colony is dying, gas produced by decomposition may cause it to float loose, sending gelatinous globs floating down the river. ...moss animal.
