Verulux cypselurus ( Syn .: Rhabdamia cypselurus ) is a small, six centimeters long marine fish that grows in the Red Sea , the Persian Gulf and the tropical Indo-Pacific from East Africa to the coast of Western Australia, north to the Ryūkyū Islands and east to the Marshall Islands , Fiji , Tonga and New Caledonia occurs.
features
The fish have a moderately elongated, laterally flattened body, which is covered with weak round or crest scales. The caudal fin is forked with 15 branched and unbranched upper and lower fin rays . The Hypuralia 1 + 2 + 3 + 4 have grown together. The lower jaw, the premaxillary and vomer are each covered with a row of slender teeth. The palatine can be edentulous or have a row of teeth. The supramaxillary, a bone of the upper jaw, is missing. Burrs and edges of Vorkiemendeckels (Preoperculum) are smooth. The stomach and intestines are blackish, the peritoneum silvery. In contrast to the genus Rhabdamia , to which Verulux cypselurus was previously assigned, the fish have a luminous organ under the Cleithrum .
