Bony Fish

Identification & Biology

  • IdentificationDeep, oval body with a slightly pointed snout. Silver-grey body with 8 to 9 faint dark vertical bars on the flanks. A prominent dark spot on the caudal peduncle and at the base of the pectoral fin. Strong incisor-like front teeth.
  • SizeUp to 45 cm total length, commonly 15 to 25 cm.
  • Social HabitSchooling species, often in groups of 5 to 20 near rocky structures. Commonly mixes with other seabream species.
  • HabitatRocky reefs, seagrass beds, and mixed substrates. One of the most common reef fish in the Mediterranean.
  • Depth1 to 50 m, most common between 3 and 20 m.
  • Feeds OnAlgae, worms, crustaceans, molluscs, and sea urchins. An omnivorous grazer.
  • DistributionEastern Atlantic from the Bay of Biscay to South Africa, including the entire Mediterranean Sea.
  • DescriptionOne of the most familiar and commonly encountered seabream on every Mediterranean reef dive. Small groups patrol rocky areas, grazing on algae and invertebrates. The prominent dark spot on the tail stalk is the quickest identification feature. A protandrous hermaphrodite that starts as male and may change to female.
