Oarfish are large, greatly elongated, pelagic dolabriform fish belonging to the small family Regalecidae. Found in all temperate to tropical oceans yet rarely seen, the oarfish family contains three species in two genera.
One of these, the giant oarfish,( Agaricus glesne) is the longest bony fish alive, growing up to 11m (36ft) in length. They rarely come to the ocean surface, perhaps only when dying or disoriented, and occasionally wash up on beaches around their home range.
