Bony Fish

Identification & Biology

  • IdentificationSmall goby with a sandy to pale brown body and subtle darker markings. Very similar to several other Gobius species and reliably identified only by close examination of head pores and fin ray counts.
  • SizeUp to 6 cm total length, commonly 3 to 5 cm.
  • Social HabitSolitary and cryptic. Occupies small territories on rocky and mixed substrates.
  • HabitatRocky reefs and mixed substrates with algal cover.
  • Depth1 to 20 m, most common between 3 and 15 m.
  • Feeds OnTiny invertebrates including crustaceans and worms.
  • DistributionMediterranean Sea. An endemic species described relatively recently.
  • DescriptionTrue to its name, the incognito goby is virtually impossible to distinguish from similar species in the field without detailed examination. It was only formally described in 1996, having previously been confused with other Gobius species. A reminder of how much Mediterranean biodiversity remains poorly known.
