Acanthaluteres brownii is a marine fish from the Monacanthidae family. It lives off the southern coasts of Australia and feeds on algae among reefs and seagrass beds.
Acanthaluteres brownii differs from closely related species by its special brown coloration and the shape of the spine on its back. This fish is important because it eats algae and helps maintain balance on the seabed.
Immature form that undergoes metamorphosis before adulthood.
