Description

The smalltooth emperor is a large emperor (Lethrinidae) from the Indo-West Pacific. The species grows to about 80 cm and has an elongate, silver-grey body with a pointed snout and sometimes a few oblique dark lines below the eye. As a bottom-oriented predator it lives on and near reefs between about ten and two hundred metres and hunts fish, molluscs and crustaceans. Although a valued food fish, cases of ciguatera poisoning have been reported from large specimens.
