Giant oarfish

A giant oarfish skeleton.

Scientific name: Regalecus glesne

Bones of a monstrous fish
Giant oarfish can grow up to eight metres (26 feet) long –over twice the length of this skeleton – making them one of the longest fish in the sea. Scientists know little about the behaviour of giant oarfish because they live in the deep ocean. However, rare glimpses of their silvery, snake-like bodies and bright red fins are thought to be behind many tales of sea serpents.
