Bony Fish

Identification & Biology

  • IdentificationSmall blenny with a robust body and a large head. Males develop a prominent fleshy crest on the head during breeding and turn dark with vivid pale markings. Females are smaller and plain brown.
  • SizeUp to 13 cm total length, commonly 6 to 9 cm.
  • Social HabitMales are fiercely territorial and guard nest holes. Females visit males to deposit eggs.
  • HabitatRocky intertidal and shallow subtidal zones, harbours, and breakwaters. Often found in artificial structures like pipes and holes in concrete.
  • Depth0 to 10 m, predominantly intertidal to 5 m.
  • Feeds OnAlgae and small invertebrates scraped from rock surfaces.
  • DistributionMediterranean Sea and adjacent Atlantic coast.
  • DescriptionBreeding males are among the most dramatic-looking small fish in the Mediterranean, with a tall head crest and dark body marked with vivid pale spots. Males compete for nest holes in the intertidal zone, displaying their crests to rivals. Studies have shown that female peacock blennies preferentially choose males with the largest crests.
