Bony Fish

Identification & Biology

  • IdentificationVery long, laterally compressed body with an extremely elongated beak lined with fine teeth. Dark blue-green back and silver flanks. Body is noticeably flattened from side to side compared to other needlefish.
  • SizeUp to 140 cm total length, commonly 60 to 100 cm.
  • Social HabitUsually solitary or in very small groups near the surface. Lurks near floating objects.
  • HabitatSurface waters of the open ocean and coastal areas. A pelagic species that stays close to the surface.
  • DepthSurface to 10 m, almost always in the top few metres.
  • Feeds OnSmall fish caught with rapid lateral strikes of the toothed beak.
  • DistributionTropical and subtropical Atlantic Ocean, occasionally entering the Mediterranean Sea.
  • DescriptionThe largest needlefish likely to be encountered in the Mediterranean, though it is an uncommon visitor. Its laterally compressed body distinguishes it from the garfish and other needlefish. Like all needlefish, it can leap from the water when startled and has occasionally caused injuries to people.
