Zooecium → It is formed from "zoo-" (from Greek "zōion", meaning animal) and "-ecium" (from Greek "oikos", meaning house or dwelling). The word refers to a dwelling or habitat of animals, particularly in the context of certain marine organisms.
Think of 'zoo' which relates to animals ('zōion') and 'ecium' meaning a place or house. This helps you remember that 'zooecium' refers to a place where animals live.
