Etymology: Gonium is best known as the name of a genus of green algae, a tiny freshwater organism whose cells form flat, square colonies of about sixteen individuals, each with its own pair of whip-like flagella. The naturalist Otto Friedrich Müller gave the genus its name in New Latin, and it likely draws on the Greek "gonia," meaning angle, a nod to the colony's angular shape. The ending is older and more productive than the genus. It comes from the Greek "gonos," meaning offspring or seed, which is related to the verb for being born. Biologists attach it to reproductive structures: an oogonium is the cell or chamber where eggs form in algae and fungi, and a spermogonium is a comparable structure that produces sperm in some fungi.

Synonyms: alga genus, colonial algae
