Interesting Info

  • The Deceitful Velvetfish lives on soft seafloor from Exmouth Gulf in Western Australia, across to Deception Bay in Queensland—often hiding where sand or mud meets the reefs.
  • It is the sole species in its genus, making it a true one-of-a-kind fish.
  • Its skin is covered in a velvety layer of tiny scales and filaments that help it blend in with algae, rocks, and sponges.
  • Colouration varies from mottled brown to reddish or orange tones, often resembling encrusting corals or seaweed.
  • The name “Deceitful” reflects its incredible ability to disguise itself so well that it often goes unnoticed by predators—and even divers.
  • Velvetfishes are relatives of the stonefishes and scorpionfishes, and like them, they are thought to possess venomous spines for protection.
  • It lives on rocky reefs and among kelp beds, usually in shallow coastal waters down to about 30 m (100 ft).
  • The Deceitful Velvetfish is an ambush predator, feeding on tiny crustaceans and fishes that come too close.
  • Instead of chasing prey, it stays perfectly still, blending into its background until the moment it strikes.
  • Very little is known about its reproduction, but like related species, it likely produces adhesive eggs that attach to the seafloor or weed.
  • Its lifespan is unknown, though small reef fishes in this group often live 3–5 years.
  • Predators may include larger reef fishes and octopuses, but its camouflage makes it difficult to find.
  • It is considered extremely rare, with only a handful of scientific records and specimens ever collected.
  • Because so few specimens exist, scientists are still learning about its ecology, behaviour, and evolutionary relationships.
  • The Deceitful Velvetfish reminds us how many hidden creatures still live along Australia’s coasts, waiting to be studied.

Snorkeling & Diving

Observing the Deceitful Velvetfish in the wild can be a thrilling experience for snorkelers and divers. Due to their preference for shallow waters, they are easily accessible for snorkeling activities, especially in rocky reef areas. Divers can enjoy getting up close to these small, camouflaged fish and witnessing their intricate patterns.
