Etymology

The word hydroid comes from the Greek root hydro- meaning 'water' and the ending -oid meaning 'like' or 'in the form of'. So a hydroid is a 'water-like' animal — a small creature that lives in water and often forms colonies, which explains its modern meaning as an aquatic, polyp-dominated animal.
