features
Eumecichthys fiski can reach a body length of 150 cm. The body height is around three percent of the standard length at its highest point , the maximum body width 1.3% of the standard length. The length from the front end of the upper jaw to the rear end of the gill flap is six percent of the standard length. The head has a horn-like, horizontally protruding rostrum at its tip, so that the total head length is about ten percent of the standard length. The head and body are silvery, the trunk shows numerous (24 to 60) vertical bands. The elongated dorsal fin, which extends over the entire body, is supported by 310 to 392 fin rays and, like the caudal fin, is purple in color. The dorsal fin extends in front to the front end of the "horn", the first fin rays are greatly elongated and form an upward-pointing "head" at the front end of the head. The small anal fin has five to nine fin rays, the pectoral fins 14 and the caudal fin about 13. The fin rays of the caudal fin are much thicker than those of the other fins. The pseudobranch is well developed, the number of Branchiostegal rays is six. Each premaxillary has a row of seven small, conical teeth on the side. In the front there are six to seven curved teeth with large gaps between them. Each lower half of the jaw has two irregular rows of curved teeth that are also far apart.
Eumecichthys fiski is a mesopelagic species and lives at depths of 1000 meters.
