Attribute Details
Scientific Name Haliotis diversicolor squamata
Common Name Scaly Australian Abalone
Distribution Recorded from northern Australia and the wider Indo-Pacific region, including tropical reef areas of Southeast Asia.
Habitat Found in warm, shallow reef environments, usually on coral rubble, rocky surfaces, reef crevices, and algae-covered substrate.
Depth Range Shallow reef waters.
Average Size 5 to 7 centimetres.
Maximum Size Around 8 to 10 centimetres.
Commercial Status Minor commercial interest overseas / Non-commercial in Australia.
Key Characteristics This small tropical abalone has an oval, ear-shaped shell with a patterned and textured outer surface.

The shell edge carries a row of open respiratory pores, and the exterior can appear scaly or rough compared with smoother abalone species.

About Scaly Australian Abalone

The Scaly Australian Abalone (Haliotis diversicolor squamata) is a small, decorative tropical abalone associated with warm reef environments across northern Australia and the wider Indo-Pacific. Unlike the larger southern species that support Australia’s major commercial abalone fisheries, this species is much smaller and is not a significant seafood species in Australia. It lives among coral rubble, rocky crevices and algae-covered reef surfaces, where its mottled shell pattern helps it blend into the surrounding habitat. For shell collectors and marine biodiversity records, it is mainly recognised for its compact ear-shaped shell, rough scaly surface and colourful markings.
