IPA: //zoʊˈɛəriəm//
KK: /zoʊˈɛəriəm/
A group of zooids that form a colonial or compound living organism.
The zoarium of the coral reef is made up of many interconnected polyps.
Zoarium → It is formed from "zoon" (from Greek "ζῷον", meaning animal) and "-arium" (meaning a place for). The word "zoarium" refers to a place for animals, often used in the context of a zoo or animal habitat.
Think of 'zoon' meaning animal and '-arium' meaning a place — so a zoarium is a place for animals.
