damselfish,

common name for members of the large family Pomacentridae, marine fishes of tropical waters. Common in the West Indies and along the Florida coasts are the sergeant-major, named for its vertical stripes, and the reef fish, found among coral reefs. The clownfish and blue devil are popular aquarium species. Males of this family guard the eggs zealously. Damselfishes rarely grow to more than 6 in. (15 cm) in length. Certain members of the family, known as anemonefishes, are found associated with sea anemones, which are injurious to the fishes' predators, and which afford protection to the anemonefishes. Damselfish are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.
