More Info


Distribution

Offshore reefs of Western Australia (Rowley Shoals & Scott Reef), and Ashmore Reef, Timor Sea, to Port Hacking, Sydney, New South Wales; also Cocos (Keeling) Islands and Christmas Island in the eastern Indian Ocean, reefs in the Coral Sea, and the Lord Howe Island region in the Tasman Sea. Elsewhere the species occurs in the tropical, Indo-west-central Pacific.
Inhabit rubble and sandy areas in lagoon and seaward reefs, deeper reef slopes, and shallow silty estuaries and inlets. Groups hover above the bottom to feed on zooplankton. Monogamous pairs occupy a burrow, although juveniles may dive into the same burrow when threatened.

Features

Dorsal fin VII, 25-29; Anal fin I, 24-27; Vertebrae 26-27. 
Chin with a median, fleshy protuberance narrowing to a thin fold. Scales embedded, close-set, non imbricate (except on posterior part). First dorsal fin lower than second; second dorsal and anal fins elevated anteriorly. 

Colour

Pale to bluish-grey; pectoral fin base with a narrow, pale blue-edged, black band; postorbital head with irregular, pale to iridescent blue bands and spots. 

Feeding

Hovers above the substrate to feed on zooplankton.

Similar Species

Although similar to Ptereleotris heteroptera, the Greeneye Dartgoby lacks a bluish mark on the tail.

Etymology

The specific name microlepis is from the Greek mikros (= small) and lepis (= scale) in reference to the very small embedded scales of this species.
