Lethrinus nebulosus, the spangled emperor, green snapper, morwong, north-west snapper, sand bream, sand snapper, sixteen-pounder, sharie, sheri and yellow sweetlip, is a species of marine ray-finned fish belonging to the family Lethrinidae, the emperors and emperor breams. This species is found the Indo-West Pacific region.

Taxonomy Lethrinus nebulosus was first formally described as Sciaena nebulosa by the Swedish-speaking Finnish explorer, orientalist, naturalist Peter Forsskål and published in 1775 in Descriptiones animalium edited by Carsten Niebuhr with no Type locality being given but it is assumed to be the Red Sea. In 2022 the population of this species found off the coast of Southern Africa south of northern KwaZulu-Natal was recognised as a valid separate species from L. nebulosus, Lethrinus scoparius. Some authors place the genus Lethrinus in the monotypic subfamily Lethrininae, with all the other genera of Lethrinidae placed in the Monotaxinae, however, the 5th edition of Fishes of the World does not recognise the subfamilies traditionally accepted within the family Lethrinidae as valid. The family Lethrinidae is classified by the 5th edition of Fishes of the World as belonging to the order Spariformes.

Etymology Lethrinus nebulosus has the specific name nebulosus which means "cloudy", Forsskål described it as having "longitudinal clouds of blue and yellow-brown" which is thought to be an allusion to the irregular dark bars that sometimes appear on its flanks.

This fish occurs in the waters of East Africa to the southern parts of Japan. It also lives in Australian coastal waters, and has been recorded in the Red Sea, Persian Gulf and New Caledonia, where it is one of the major commercial fish.

Habitat Lethrinus nebulosus inhabits both marine and brackish waters at depths of between 10 and 75 metres.
