The false snapper (Nemipteridae) live in the tropical and subtropical Indian Ocean and the western Pacific , mostly in coastal waters with a sandy bottom. In some countries, such as the Philippines , China and Japan , bill snapper is an important food fish.

features

The over 60 species are 9 to 35 centimeters long. While young animals are often very colorful, the adults have a simple coloration. The dorsal fin is continuous, the front part with hard rays is supported by ten spines, the rear part with soft rays is supported by nine fin rays. In the anal fin there are three spines and seven soft rays (eight in Nemipterus virgatus ). The caudal fin is forked, the upper part of Nemipterus elongated like a filament. The number of Branchiostegal rays is six and the number of vertebrae is 24.

Way of life

Mock snapper feed on small, bottom-dwelling fish and invertebrates such as cephalopods , crustaceans and bristle worms .

Like many of their relatives, the false snapper are protogynous hermaphrodites . That is, in the course of their life they are first females and then transform into males.

Systematics

The pseudo- snappers , together with the sea ​​bream (Sparidae) and the big-headed snappers (Lethrinidae), form a group of related "sparoid" families, which some scientists regarded as the superfamily (Sparoidea) of the Percoidei , but later as a separate order (Spariformes) from the perch-like ( Perciformes) was spun off.

There are five genera and almost 70 species described. Many of these species are morphologically identical and only differ in their coloration.
