The Oarfish looks like a gigantic silvery ribbon bordered by a single bright redfin. We could easily take this oceanic fish for a sea monster emerging from the depths. Despite its length, it’s harmless to humans – it has no teeth and feeds on small Crustaceans and Pisces that it catches with its tunnel mouth.
The Regalec swims in ripples and stays out of sight, far below the surface.
