Oarfish

Life of Sea | | 
Army and Weapons | Oarfish Oarfish is large, very elongated, pelagic fish Lampriform consists Regalecidae small family. Are to be found in all tropical oceans yet rarely seen, oarfish family contains four species in two genera. One of them, the king of herrings (Regalecus glesne), is the longest bony fish alive, up to 17 meters (56 feet) long.

Common name refers to one of oarfish thought they were very solid body and elongated, or former beliefs (but now discredited) that the fish "row" themselves through the water with their pelvic fins. Regalecidae surname derived from the Latin regalis, meaning "royal". The occasional beachings oarfish after storms, and their habit of lingering at the surface when sick or dying, make oarfish a probable source of many sea serpent stories.
Although the larger species are considered game fish and are (to a small extent) fished commercially, oarfish are rarely caught alive, their flesh is not respected because of its gelatinous consistency. Rare meeting with divers and accidental catches have supplied what little is known of oarfish behavior and ecology. Apparently solitary animals, oarfish may frequent significant depths up to 1,000 meters (3,300 feet). An oarfish measuring 3.3 meters (11 ft 4 in) and 63.5 kg (140 lb) were reported to have been arrested on February 17, 2003 by Ms Val Fletcher using bait fishing with squid, at Skinningrove, United Kingdom.
A photograph on display in bars, restaurants, hotels and markets throughout Laos and Thailand were captioned, "Queen of Nagas seized by American Army at Mekhong River, Laos Military Base on June 27, 1973 with a length of 7.80 meters," is a hoax . This photo was taken by Dr. Leo Smith of The Field Museum, of oarfish found in late 1996 by U.S. Navy SEAL trainees on the coast of Coronado, California, United States
The oceanodromous Regalecus glesne recorded as spawning off Mexico from July to December, all species are suspected non-guarders and release brightly colored, floating eggs, up to 6 millimeters (0.24 inches), which is incorporated into the zooplankton. The eggs hatch after about three weeks of being very active larvae, which eat other zooplankton. 
Larvae had little in common with adults, with a long dorsal fin and pelvic and extensible mouth. Larval and juvenile has been observed hovering just below the surface. In contrast, adult oarfish are rarely seen at the surface when sick or injured.
