Description

The Hovering dartfish is a dartfish (Gobiidae) from clear coastal and reef water of the western Atlantic and Caribbean. The species grows to about 12 cm and has a slender, streamlined body with large eyes and graceful, sometimes elongate fins. As a social fish it hovers in pairs or groups just above sand and coral rubble and snaps at passing zooplankton; when threatened it darts lightning-fast into a burrow in the bottom. The fish is harmless to humans.
