Bony Fish

Identification & Biology

  • IdentificationDeep, compressed body with a steep forehead. Silver-grey body marked with 6 to 8 horizontal dark brown to black stripes. Large eyes and a relatively small mouth with thick lips.
  • SizeUp to 60 cm total length, commonly 25 to 35 cm.
  • Social HabitSchooling species found in loose to dense aggregations near rocky structures. Often mixes with other grunt species.
  • HabitatRocky reefs, wrecks, and boulder fields in coastal and offshore waters.
  • Depth10 to 100 m, most common between 20 and 60 m.
  • Feeds OnCrustaceans, molluscs, worms, and small fish taken from the seabed, primarily at night.
  • DistributionEastern Atlantic from Portugal to Angola and throughout the Mediterranean Sea.
  • DescriptionA handsome, striped fish that gathers in schools around underwater structures. The name 'grunt' comes from the sounds it produces by grinding its pharyngeal teeth, amplified by the swim bladder. Divers commonly encounter schools near wreck sites.

Biology

Behaviour & Diet

Feeding Strategy

Feeds nocturnally on small crustaceans, polychaete worms and molluscs found over sandy and rocky substrates. Uses its pharyngeal teeth to crush hard-shelled prey.

Nocturnal forager

Reproduction

A broadcast spawner that releases pelagic eggs into open water during warmer months. Larvae are planktonic before settling to the benthos.

Seasonal spawning

Behaviour & Defence

Forms loose aggregations in caves and overhangs during daylight, relying on group vigilance to detect predators. Retreats quickly into crevices when threatened.
