Ribbonfish

Trachipterus trachypterus

The Sense fish ( Trachipteridae ) or ribbon fish ( not to be confused with the similarly mentioned Cepolidae ) are a family of gloss Fishy ( Lampriformes ). The ten 1.1 to 3 meters long expectant pelagic species live in all oceans including the Mediterranean and the Arctic Sea.

Features

Sense fish have cycloid scales or modified ctenoid scales, which can be provided with tubercles. The siberfarbenen by Guaninplättchen in the skin fish have a long, the whole body length comprehensive dorsal fin, which is constantly moving with red muscle fibers waves. The small tail fin consists only of the almost perpendicular upward top, fan-shaped lobe. An anal fin is missing. The pelvic fins have a single to ten fin rays, the pectoral fins are small and horizontally aligned. The eyes are large. A swim bladder is, if at all, only a rudimentary state. During the growth, the body shape changed significantly ( allometry ). The number of vertebrae is 62 to 111 Sense fish have no fins, her shoulder girdle is small. The skeleton is fragile, the mineral- poor and water-rich bones are light.

Your normal swimming position is oblique, with the head upwards, the longitudinal axis of the fish forms an angle of about 60 ° to the horizontal. Only during fast swimming, they are horizontal in the water. The juvenile stages of fish have long fins Sense beams that serve as floating extensions. In Iceland we saw swarms with hundreds of fish of the genus Trachipterus band.

Sense fossil fish are known by the generic Protolophotus from the Oligocene.
