  • HabitatRocky reefs, wrecks, and underwater structures. A western Atlantic species that is a rare vagrant in the Mediterranean.
  • Depth3 to 60 m.
  • Feeds OnCrustaceans, worms, and small molluscs foraged from sandy areas at night.
  • DistributionWestern Atlantic from Florida to Brazil. Occasional vagrant records in the eastern Atlantic and Mediterranean.
  • DescriptionA colourful western Atlantic grunt that appears only as a rare vagrant in the Mediterranean. Named for the sounds it produces by grinding its pharyngeal teeth. If encountered in Mediterranean waters, it represents an unusual transatlantic dispersal event.
