The bodies of threadfin breams are long and oval-shaped. They are covered in large scales and have small mouths. Certain species have a spine located below their eyes.
Other species have an extended filament on the upper caudal lobe. They are usually bright in colour, varying from silver and black to light and darker brown, at times marked by a yellow line.
Threadfin breams belong to the Nemipteridae family which comprises of five genera and 64 species. They can be found near coral reefs, swimming near the bottom hunting for food.
They also occur in river mouths and are closely related to the snapper. Threadfin breams are pelagic spawners.
