Zu elongatus

Zu elongatus, or the taper-tail ribbonfish, is a species of ray-finned fish within the family Trachipteridae. The species distribution is poorly known, and while it likely lives in temperate and tropical waters of all oceans, but has only been encountered in the Atlantic Ocean- off the coasts of Namibia and the western Cape of South Africa- and in the Pacific Ocean off New Zealand. It inhabits mesopelagic waters up to 1200 meters below sea level. Other common names for this species include "scalloped dealfish" and spitsstert-lintvis in Afrikaans.
