The giant oarfish, also known as the king of the herring, Pacific oarfish, ribbon-fish, and streamer fish, was originally described by the Norwegian biologist Peter Ascanius in 1772.
Regalecus glesne is the longest bony fish alive. It can reach a length of over 50 feet and weigh as much as 600 pounds.
The generic name Regalecus is derived from the latin word regalis, meaning ‘royal.’ The origin of the oarfish name is unknown, but may refer to the oar-shaped body or the long, oar-like pelvic fins.
Regalecus glesne is a pelagic species found living at great depths to 3,280 feet (1 km), but more typically to depths of 656 feet (0.2 km) throughout the deep seas of the eastern Atlantic Ocean and Mediterranean Sea. Read more.
