Interesting Info

  • The Common Dart is a sleek, silver fish that speeds through the surf like a torpedo.
  • It grows up to 75 cm (30 in) long and around 2.3 kg (5 lb), though most caught by anglers are smaller.
  • Its deep body and forked tail are designed for quick bursts in wave-tossed waters.
  • In Australia, it has been recorded from Western Australia’s northwest coast and occasionally further east in tropical waters.
  • Juveniles school in sheltered bays, estuaries, and lagoons, then move into surf beaches as they grow.
  • Adults patrol surf zones, sandy shores, and shallow reefs, often feeding just beyond the breakers.
  • Their diet includes crabs, worms, bivalves, prawns, and small fish stirred up by crashing waves.
  • They use strong throat plates to crush hard-shelled prey like mussels and clams.
  • Common Darts spawn offshore during warmer months, releasing eggs into open water where currents carry them.
  • Larvae drift in the plankton before settling in estuaries and sandy bays as juveniles.
  • They mature by about 3 years old and live for roughly 7 years.
  • Their silvery sides glint in the surf, making them exciting sights for snorkellers exploring sandy channels.
  • They are prized sport fish on light tackle, offering strong runs and acrobatic fights.
  • Their habit of feeding in turbulent surf zones helps keep sandy-shore ecosystems balanced.
  • The name botla comes from an old African word for this species.
