More Info


Distribution

Northern Great Barrier Reef, to Goat Island, southern Queensland. Elsewhere the species occurs in the north-eastern Indian Ocean and western Pacific from southern Japan to north-eastern Australia and New Caledonia. Inhabits coastal seagrass and sandy areas with mixed coral and rubble on reef flats, reef crests, in channels and lagoons, in depths to about 25 m. it inhabits reef crests and slopes with algae and soft corals. Juveniles occur inshore and often form small aggregations in seagrass beds where near mangrove or freshwater run-offs

Features

Dorsal fin XIII, 7; Anal fin III, 9; Pectoral fin ii, 13-14; Vertebrae 11+16=27.

Colour

Caudal peduncle with a broad pale saddle extending anteriorly to below posterior end of dorsal fin base; a pale wedge-shaped band present midlaterally on side below about 5th dorsal fin spine; head dusky above level of mouth, covered by tiny pale spots (orange in life).

Feeding

Like most other species in the family, the Anchor Tuskfish is a broad spectrum feeder, and is often seen turning over lumps of coral in search of hard-shelled prey.

Etymology

The specific name anchorago may refer to an anchor-like colour pattern, as perceived by its author (Gomon 2017).
