Description

The giant oarfish is the longest bony fish in the world, of the family Regalecidae from temperate and tropical oceans. The species can reach about 8 metres and has an extremely elongate, ribbon-like, silvery body with a red dorsal fin running its whole length and long, thread-like front fin rays. It lives in the open ocean, usually at several hundred metres, and is rarely seen alive; stranded or dying individuals at the surface fed sea-serpent legends for centuries. As a plankton feeder it filters small zooplankton, especially shrimp-like forms, from the water. The species is harmless to humans.
