The giant oarfish (Regalecus glesne) is the longest known species of bony fish on Earth. The longest on record was 11 metres (36 ft); however, unconfirmed specimens of up to an astonishing 17 metres (56 ft) have been reported. Its huge size and its undulating method of swimming has led many to speculate that it may be the source of “sea serpent” legends.
Like many denizens of the deep, we know little of their biology or lives. They are occasionally caught by fisherman or wash up ashore, but live sightings are few and far between.
