Etymology: Zoantharians are the sea anemones and their close relatives, and the word's history is a neat example of scientific naming built from Greek parts. The name rests on "Zoantharia," the taxonomic name for the order, which combines Greek "zōion," "animal," with "anthos," "flower." The animals were named for their flower-like appearance, with a living body that looks like a blossom opening and closing in the water. The final element "-an" is a suffix used to form adjectives and nouns meaning "belonging to" or "related to" a group, so a zoantharian is one of the animals belonging to the Zoantharia. This pattern, with a Latinised Greek name plus "-an," is standard in biological terminology, allowing scientists to name members of a group from its formal name.
