FAQ
Frequently Asked Questions
No, it is a rare, technical term used almost exclusively in advanced biological contexts.
The singular is 'zoon', but this form is even rarer and largely obsolete. 'Zooid' or 'polyp' are more common terms for the singular concept.
No. It specifically refers to the individual animals that are part of a connected colonial organism, such as in corals, bryozoans, or some jellyfish.
Use it as a plural noun, typically preceded by a descriptor like 'colonial' or 'coral,' and followed by a plural verb: 'The coral's zoa were extended to feed.'
