Interesting Info

  • The Curious Wormfish is a small, slender reef fish recorded in Australia only from the Houtman Abrolhos in Western Australia and the northern Great Barrier Reef in Queensland.
  • They have an extremely elongated, eel-like body, pale pink to reddish in colour, often with faint stripes along the sides.
  • The head is small with tiny eyes, well suited for their burrow-dwelling lifestyle.
  • Curious Wormfish live in sandy areas near coral reefs, where they excavate burrows for shelter.
  • They are often seen peeking out of their burrows, retreating instantly when disturbed.
  • They can occur in small groups, with several individuals sharing the same sandy patch near coral rubble.
  • Their diet consists of tiny planktonic crustaceans and other small invertebrates drifting close to the seabed.
  • The species name “curiosus” reflects their behaviour of watching the world from their burrow entrances, appearing curious before darting back.
  • Juveniles are similar in form to adults but often appear more translucent.
  • Reproduction occurs through pair spawning, with eggs and larvae drifting as plankton until settling into sandy reef areas.
  • They play a role in reef food webs as prey for larger fishes and as plankton feeders themselves.
  • Other common names include Worm Goby and Curious Worm Goby, though they are wormfishes rather than true gobies.
