A major group of marine animals that includes corals, sea anemones, and sea pens, characterized by a single opening in their cup-shaped body.
From Greek 'anthos' (flower) and 'zoion' (animal), literally 'flower-animals,' because early naturalists thought these creatures were flowers.
When Europeans first saw coral reefs, they genuinely thought corals were flowers because they're so pretty and don't move—it took centuries to realize they're actually carnivorous animals that eat plankton using tentacles covered in stinging cells!
