How to tell it apart

Its pale pink-grey body and yellow fins look similar to several other reef snappers, but this species carries a single black spot or blotch toward the rear of its body. In older, larger fish that spot shrinks and becomes more oblong.

Appearance

This snapper has a fairly deep body with a gently sloping forehead. Its overall colour is whitish to pink or grey, and its fins are yellow.

Habitat

One-spot snapper live around coral reef areas across the tropical Indo-Pacific, usually staying close to shelter such as caves, large coral formations, or wreckage, from just below the surface down to about 60 metres.

Behaviour

This is a nocturnal hunter that feeds mainly on fish, along with bottom-dwelling crustaceans, at night. It is usually seen alone, though it sometimes gathers in small schools.

Did you know?

Its species name, monostigma, means "one mark" - a reference to the single black spot that gives this snapper its common name, a mark that is bold in young fish and fades with age.
