The moon perch ( Mene ) are a species and family of fish that are extinct except for one species. They are known to be fossilized since the Paleocene . The oldest species is Mene purdyi from Peru . Several fossil species from the Lower Eocene were found in the fossil site of Monte Bolca near Verona in Italy .

  • Mene oblonga

  • Mene rhombea

There is only one living species left today, Mene maculata , which lives in the Indo-Pacific from the coast of East Africa to southern Japan and the coast of northeastern Australia . The fish live near the coast above the continental shelf and near large islands at depths of 50 to 200 meters. They also go into the brackish water of the estuaries. Mene maculata feeds on bottom-dwelling invertebrates. The fish, which grow to a length of 30 centimeters, are fished commercially and come fresh or dried on the market.

features

Moonfish have a disc-shaped shape (μήνη "moon") and are flattened laterally, with a pronounced, deeply arched chest and stomach region. The ventral fins of adult fish are long and thread-like. The anal fin has no hard rays and is supported by 30 to 33 soft rays. It extends from the base of the pelvic fins to the root of the caudal fin, but is very low. The caudal fin is deeply forked, the dorsal fin is supported by 43 to 45 soft rays and is only low.

Systematics

The systematic position of the moon bass was uncertain for a long time. They have already been placed as a separate order, Meniformes and close to the Tetraodontiformes (which are then regarded as prepercomorphs) and the Beryciformes . They were later placed in the order of the perch-like . Betancur-R. and employees assigned them to the Carangaria in their revision of the system of bony fish published in spring 2013 .
