What do bryozoans look like?

These tiny animals often colonize by branching out into shapes that look more like spaghetti than living animals. Bryozoans are made up of colonies of individuals, called zooids. ... Zooids are very tiny (less than one thirty-second of an inch), and come in shapes ranging from oval and box-like to vase-like and tubular.

What is inside a bryozoan?

Within their bodies, freshwater bryozoans form hard, round statoblasts, which function like seeds. In winter or during drought, the colonies die, but the dissolving dead zooids free the statoblasts, which can disperse widely. These endure until conditions permit new growth. Each statoblast can create a new colony.
