1. noun

A microzooid is an individual zooid, typically one of a colonial organism, such as a bryozoan, that is not a full-sized zooid but rather a small, often reproductive or larval form.

“The researchers studied the microzooids of the bryozoan species to understand its life cycle.”

2. noun

In some contexts, a microzooid is used more broadly to refer to any small zooid or individual animal that is part of a larger colony or group.

“The biologist examined the microzooids that formed the basis of the coral reef ecosystem.”
