Bony Fish

Identification & Biology

  • IdentificationVery small blenny with a rounded head and short orbital tentacles. Body is yellowish to olive with reddish-brown mottling. Males develop darker colouration during breeding.
  • SizeUp to 4 cm total length, typically around 3 cm.
  • Social HabitSolitary and territorial. Males guard small nesting sites in empty barnacle shells and tiny crevices.
  • HabitatRocky intertidal and shallow subtidal zones. Lives in very small shelters on exposed rock surfaces.
  • Depth0 to 10 m, predominantly intertidal to 3 m.
  • Feeds OnAlgae and tiny invertebrates scraped from rock surfaces.
  • DistributionMediterranean Sea and nearby Atlantic coast.
  • DescriptionA tiny blenny that inhabits the same shallow rocky habitats as several other small blenny species. Named after the Dalmatian coast where it was first described, it is one of the smallest fish on Mediterranean rocky shores. Its small size and cryptic habits make it a challenge to spot.

Range
