Characteristics

''Macolor'' snappers are medium-sized with a relatively deep, oblong body. They have quite a large mouth which can be ptrotracted. Each jaw has an outer band of conical teeth which are enlarged into canine-like teeth at the front, on the inside of these are bands of bristle-like teeth, at the side in the upper jaw and set anteriorly in the lower jaw. The vomerine teeth are arranged a rough chevron there is no a median posterior extension. There is a deep incision on the lower edge of preopercle. The

Fisheries

''Macolor'' snappers are considered to be good eating and are frequently encountered in fish markets but in small numbers. They are typically sold fresh.
