Bony Fish

Identification & Biology

  • IdentificationOval, deep body with two prominent dark vertical bands: one behind the head and one on the tail base. Silver-grey body with faint golden or yellowish tints. Dark spot at the base of the pectoral fin.
  • SizeUp to 45 cm total length, commonly 15 to 25 cm.
  • Social HabitSchooling species, often seen in groups of 5 to 20 over rocky reefs. Juveniles form larger schools.
  • HabitatRocky reefs, seagrass beds, and boulder fields. One of the most common reef fish in the Mediterranean.
  • Depth1 to 160 m, most common between 3 and 30 m.
  • Feeds OnWorms, crustaceans, molluscs, and algae. An omnivorous grazer.
  • DistributionEastern Atlantic from the Bay of Biscay to South Africa, including the entire Mediterranean Sea.
  • DescriptionOne of the most recognisable and commonly encountered fish on Mediterranean reef dives, instantly identified by its two bold dark bands. Small groups patrol the reef, moving between rocky cover and sandy patches. It is a protandrous hermaphrodite, starting life as male and potentially changing to female.
