Swallowtail Dart

Interesting Info

• The Swallowtail Dart gets its name from its forked tail that looks a little like a swallow’s wings.
• It’s not a giant—most grow to about 30–40 cm (12–16 in), but the biggest reach 60 cm (2 ft) and weigh close to 2 kg (4 lb).
• This dart is found in eastern Australia, stretching from the Daintree River in Queensland down to New South Wales, and even at Lord Howe Island.
• It loves sandy surf beaches and exposed coasts, where waves stir up plenty of food.
• Juveniles hang out in bays and estuaries until they’re strong enough to join the adults in the surf zone.
• Adults flash silver as they zip along wave lines or patrol sandy channels, sometimes in lively schools.
• They eat prawns, crabs, clams, and little fish—crushing hard shells with strong throat plates.
• Swallowtail Darts grow quickly and are ready to breed by age two, when they’re about the size of a dinner plate.
• Spawning happens in spring and summer, with eggs drifting out to sea before tiny larvae make their way back to shore.
• They live only about 6 years, so their lives are short but action-packed in the surf.
• Anglers love chasing them with light tackle—they strike fast and fight hard despite their modest size.
• Their shiny, laterally flattened body works like a surfboard—perfect for slipping through crashing waves.
• They help keep sandy beaches healthy by munching on small crabs, clams, and other critters in the wave wash.
• The species was named after British naturalist Richard Coppinger, who studied Pacific fishes in the 1800s.
