Individuals in bryozoan (ectoproct) colonies are called¬†zooids, since they are not fully independent animals. All colonies contain autozooids, which are responsible for feeding and excretion. Don’t you love these names–Zooids!!¬† Maybe AutoZone got their name from Autozooids!

Bryozoan fossils occur in many forms, including finger-shaped, fan-shaped, mats, spiralling fans, and massive irregular mounds. Many of the fossils, if examined closely with a magnifying glass, will show the individual pits where the individual bryozoans lived. Each animal was attached to the inside of its pit and could not leave the pit.
