	Megamouth Shark, Megachasma pelagios
		The Megamouth Shark is easily recognised by its huge, soft head and large mouth which is positioned at the anterior margin of the head.
		Male sharks are known to mature by 4 m in length.
		This vertical migration coincides with the vertical migration of the euphausid shrimps that are part of the Megamouth Shark's diet.

		The megamouth shark, Megachasma pelagios, is an extremely rare and unusual species of shark, discovered in 1976, with 37 specimens known to be caught or sighted as of 2006.
		Like the basking shark and whale shark, it is a filter feeder, consuming plankton and jellyfish, and is distinctive for its large head with rubbery lips.
		The first megamouth was captured on November 15, 1976 about 25 miles off the coast from Kaneohe, Hawaii when it became entangled in the sea anchor of a United States Navy ship.

	Megamouth Shark - Megachasma pelagios
		Because the megamouth shark is somewhat of a mystery fish and is considered the rarest of all sharks, no enemies are known.
		The shark was bewildered and evidence of the assault were clearly shown along the gills and dorsal fin.
		The megamouth shark was not known to exist until 1976, when a male got caught in a US Navy trawler's parachute anchor off the coast of Hawaii.

		Like the basking shark and whale shark, it is a filter feeder, and swims with its enormous mouth wide open, filtering water for plankton and jellyfish.
		The megamouth has a generally brownish-flish color on top and white underneath, and an asymmetrical tail with a long upper lobe, similar to the thresher shark.
		Megamouth has a large mouth with small teeth, and a broad, rounded snout, causing observers to occasionally mistake megamouth for a young orca.

		The 7th megamouth observed, a female with 471cm in total length was heavily studied and one of the conclusions is that this specimen is immature.
		This parasitic shark is presumed to be a vertical migrator on a diel cycle, spending the daytime in deep waters and ascending to midwater depths and to the surface at night.
		Megamouth had probably been encountered more times than we know, but often such large sharks are returned to the sea by their captors because of the difficulty in handling them.

		Megamouths are so rare that they were not known to exist until the first one was discovered off the coast of Hawaii in 1976.
		This would be the sixth Megamouth seen by man. When he hauled up the net, the fisherman knew that he had something unusual and he towed it seven miles by the tail, back to Dana Point Harbor.
		This Megamouth, like the previous five, was a male, which was evident by the claspers on the underside of the shark.

		Megamouth #1 was caught (this 4.5m mature male was actually snagged by a U.S.N. research vessel) off Hawaii in 1976, and described in 1983.
		In Megamouth #7, the largest lower teeth were approximately 8.5 mm in height (upper 6.5 mm) and the posteriors, 3.0 mm (upper 2.5 mm).
		The megamouth tooth can be broadly described as having a high, porous, triangular root, lacking a clearly defined nutrient groove and a lingually directed cusp which is broad and deep basally and narrow apically.

		Compagno (1990b) noted that the protrusability of the jaws in the megamouth shark may allow it to use its mouth as a bellows to suck in prey, and that open-mouthed cruising through prey concentrations was optimal for the basking shark but not the megamouth shark.
		It was thought that the shark was responding to light levels in choosing its depth range, and as light increased it correspondingly sought an optimal level by diving at dawn and conversely responded to decreasing light levels by ascending to near (but not at) the surface at dusk.
		The megamouth shark is the only known selachian victim of the semiparasitic cookiecutter shark, Isistius brasiliensis, and may be especially vulnerable to Isistius attacks because of its soft skin, epipelagic habitat in warm seas where Isistius is also found, sluggishness, and relatively slow swimming speed.

		The megamouth shark was first seen in 1976 by accident when it became entangled with a US Navy ship's anchor.
		Megamouths are named after their extremely large mouth which extends from the front of the snout to behind the eyes.
		Megamouth sharks are a bit of a mystery because so few of them have been seen and fewer of them studied.

		The whale shark is found in all tropical and subtropical oceans, along coastal regions, and enters lagoons on tropical islands.
		The megamouth shark is not likely to be seen by divers because they often live at great depths in the ocean.

		The taxonomy of this shark was finally subjected to molecular phylogenetics (using DNA to infer relatedness) with the discovery of the seventh specimen, a 4.71m (15 ½ ft) female found washed ashore in Hakata Bay, Japan in November 1994.
		In their paper for the Biology of the Megamouth Shark, Yoshitaka Yabumoto and his co-workers found that the female specimen they analysed had 83 rows of teeth in her upper jaw and 97 in her lower jaw, of which only three rows were functional.

		Shark bite: The sand tiger shark is denser than water but it swallows airs at the surface and holds it in its stomach to maintain approximately neutral buoyancy.
		Shark bite: The large eyes of the crocodile shark suggest nocturnal or deepwater activity, and possibly a habit of moving toward the surface at night and away from it in the day.
		Shark bite: Most of the basking sharks that have been caught are female (30 females caught to every one male), which indicates a possible separation of the sexes, either by time or location.

		The fourth megamouth shark, a large male, was found on the sandy shores of the Shizuoka prefecture, Japan, on January 23, 1989, before the animal was rewashed into the ocean (Nakaya, 1989).

		Examined on shore by ichthyologist Leighton R. Taylor, it soon became clear that the huge, rubbery-lipped fish was indeed a shark species, genus and family entirely new to science.
		Based on similarities in dental, gill-raker, cranial, and other skeletal characters, Maisey concluded that Megamouth was most closely related to the Basking Shark (Cetorhinus maximus), suggesting that Megamouth should be included with it in the family Cetorhinidae.
		According to Compagno's interpretation, the Megamouth Shark is ancestral to the threshers and only distantly related to the Basking Shark.

		The Megamouth Shark was recently discovered in deep water off of the Hawaiian Islands and near the shores of California, Japan and Western Australia.
		Little is known about the economic importance of the megamouth shark, though sharks in general have proven to be an essential element in the aquatic ecosystem.
		In areas where sharks were killed because of the belief that they threatened fisheries by preying on certain fish, a significant disruption of the ecosystem (such as overpopulation of small fish and planktonic animals) occurred.
