Emperors or sometimes called the scavengers are found mainly in tropical waters of the Indo-Pacific and Indian Oceans. They are excellent food fish.
Emperors are bottom-feeding carnivores consuming invertebrates and small fishes. Some species have molariform teeth which they use to eat invertebrates such as molluscs and crabs. Emperors can be solitary or schooling and do not appear to be territorial. They often form large aggregations for pelagic spawning. They have large eyes that enable them to feed at night.
There are about 41 species of emperors that make up the Lethrinidae family worldwide. Malaysia is represented by all 5 genera and about 29 species.
