Description

The flagtail wormfish is a small, worm-like goby relative from the Indo-West Pacific. The species grows to about 6 cm and has an extremely slender, partly translucent body with a long, continuous dorsal and anal fin and a conspicuous flag-shaped tail. As a bottom-dweller it hovers just above sandy bottoms near its burrow, into which it vanishes in a flash when threatened, and feeds on small zooplankton. The fish is harmless to humans and has no commercial value. The IUCN has not evaluated the species.
