Longnose emperors are easily distinguished from all other emperors by their distinctive head, with its long, pointed “nose.” Coloration is olive-green dorsally, with mottled blotches fading to creamy white ventrally. Juveniles, such as the one you caught, are found over sandy areas and patch reefs in shallow lagoons less than 30 feet deep, often in large schools. However, adults are usually solitary and are found in deeper waters on offshore reefs and along deep coral drop-offs to depths of 500 feet. Like other lethrinids, longnose emperors feed mainly on crustaceans, mollusks (including squid) and smaller fish. Sexes appear to be separate throughout their lives, and both males and females mature at 15 to 16 inches long (4 to 5 years old). In equatorial regions, these fish spawn monthly on new-moon periods, but in more temperate parts of their range — such as along the Great Barrier Reef — spawning is restricted to the spring months. This is a long-lived species, and because of this, the largest longnose emperors have gained a reputation for being ciguatoxic in places like New Caledonia.
