Bony Fish

Identification & Biology

  • IdentificationElongated, oval body with a small head and large golden-yellow eyes. Silver-grey body with faint yellow longitudinal lines along the flanks. Small mouth positioned low on the head.
  • SizeUp to 40 cm total length, commonly 15 to 25 cm.
  • Social HabitHighly gregarious, forming large, dense schools that move over reefs and seagrass beds.
  • HabitatRocky reefs, seagrass meadows, and sandy bottoms. Found in both coastal and offshore waters.
  • DepthSurface to 350 m, most common between 5 and 100 m.
  • Feeds OnAlgae, seagrass, zooplankton, and small invertebrates. One of the few Mediterranean fish that feeds heavily on plant material.
  • DistributionEastern Atlantic from Norway to Angola, including the entire Mediterranean and Black Sea.
  • DescriptionOne of the most abundant fish in the Mediterranean, recognisable by its golden eyes and silvery body. Schools of bogue are a constant presence on reef dives. Interestingly, bogue that eat certain algae can accumulate toxins that cause hallucinations in humans when consumed, a phenomenon known as ichthyoallyeinotoxism.
