Oarfish are large, greatly elongated, pelagic Lampriform fish comprising the small family Regalecidae.[1] Found in all temperate to tropical oceans yet rarely seen, the oarfish family contains four species in two genera. One of these, the king of herrings (Regalecus glesne), is listed in the Guinness Book of World Records as the longest bony fish alive, at up to 11 metres (36 ft) in length.
