Original description: Lethrinus atkinsoni Seale, 1910 - Type locality: Balabac Island, Philippines.
Eastern Indian Ocean, western Pacific: Myanmar and Indonesia east to Mariana Islands and Cook Islands, north to southern Sea of Japan and Kyushu (Japan), south to northern Australia and New Caledonia.
Inhabits seagrass beds and sandy areas of lagoons and outer reef slopes. Found singly or in schools. Feeds mainly on crustaceans, mollusks, and fish. Marketed fresh. Gonochorism is inferred for this species as sizes of males and females overlapped and male gonad morphology is typical of secondarily derived testes. Juvenile hermaphroditism is exhibited by this species.
