Lethrinidae

Bigeye snapper ( Monotaxis grandoculis ), Young Animal

The big-headed snapper ( Lethrinidae ) are a family of perch relatives. Often the fish are also called " street sweeper " which means " scavenger " comes from an unfortunate translation of the English term in Grzimek's animal life. In English, however, was " scavengers " meant.

Grosskopf snapper differ from the snappers ( Lutjanidae ) by the big head with a steeper profile, the large eyes, the dentition and the anatomy of the gill cover.

The animals live in tropical regions of the Indo-Pacific, only Lethrinus atlanticus lives in the Atlantic Ocean off the coast of West Africa.

During the day, individual animals kept under overhangs, such as table coral, on; Swarms prefer the free water on reef slopes. The bigeye snapper Monotaxis grandoculis and the Mozambique bigeye snapper Wattsia mossambica live at greater depths.

Reproduction

How many marine perch relatives are the major head snapper hermaphrodite ( protogynous hermaphrodites ), which are first female, later male.

Most species spawn in shoals in the open water. Eggs and larvae are pelagic, are distributed with the ocean currents and ensure a wide dissemination of the fish.

System

The big-headed snapper, together with the sea bream ( Sparidae ), the snout bream ( Centracanthidae ) and the Scheinschnappern ( Nemipteridae ) a group of related " sparoider " families ( Sparoidea ) the Percoidei was regarded by some scientists as a family, but later in their own order ( Spariformes ) from the Perciformes ( Perciformes ) was spun. The Lethrinidae are the sister group of sea bream.

There are two subfamilies, five genera and 39 species. Most species belong to the genus Lethrinus, some to the genus Gymnocranius while to Gnathodentex, Monotaxis and Wattsia only heard one type.
