Zooid
Definition
Example
"Each coral zooid helps build the reef by making a hard shell."
"A zooid cannot live long alone; it depends on the other members of its colony."
"Under a microscope, scientists can see hundreds of tiny zooids living together in one structure."
Explanation
A zooid is a small, individual animal that is part of a larger group of connected animals living together. Each zooid can live on its own but often depends on the group to survive. Scientists use this word to describe creatures that share one body or structure, like coral, sponges, or some sea animals. A coral reef is a large underwater structure made up of tiny animals called corals. These corals live together in groups; each small one is called a zooid. So, a zooid is one small living part of a bigger living group.
