What it is
This marine ray-finned fish belongs to the grunt family. Adults display a silvery-grey or brownish body with dark scale edges and a dusky face. The most striking feature is the pair of fleshy lips that become grossly swollen as the fish ages. The dorsal profile is convex, giving the species its humpbacked appearance. Fins are generally dusky, with the soft-rayed sections appearing darker than the rest of the body.
Where it lives
Its distribution spans the Western Pacific and Indian Oceans. Populations exist along the eastern African coast from Kenya to South Africa, including islands like Madagascar and the Seychelles. In Asia, it ranges north to the Ryukyu Islands of Japan and east to Polynesia. Australian waters host the species from Ningaloo Reef in the west, along the northern coasts, and south to Tasmania, Lord Howe Island and Norfolk Island.
How it lives
Adults inhabit coastal reefs, sandbanks and areas near estuaries at depths between 8 and 25 metres. They sometimes enter fresh water and form small aggregations in protected inshore waters or offshore deep zones. Juveniles stay near sheltered sandy shorelines. They drift with their bodies oriented sideways to the surface, mimicking fallen leaves to avoid detection. In captivity, they consume crustaceans, other invertebrates and smaller fish.
Breeding and life cycle
The species reproduces by laying eggs. Spawning events occur between distinct pairs rather than in large groups. This oviparous behaviour ensures the continuation of the population across its wide range. Specific details on egg development or larval stages are not detailed in the available records.
Fish and people
Fishers target this species using handlines and spears. The catch is highly regarded as food and is typically sold fresh in markets. A small portion of the harvest is preserved through salting. Its value as a food fish makes it a notable part of local coastal economies where it is found.
