#14	1 Oct. 1999	San Diego, California	F	5.18			On October 1, 1999, a megamouth shark (female, aprox. 17 ft) was caught in a drift gillnet and released alive in good condition. A National Marine Fisheries Service observer was aboard the commercial swordfish vessel, 30 miles west of San Diego, California. The observer was able to take four color photographs including one of the upper jaw (white lip) / lower jaw (dark spots on white chin) and others of the underside of body (no visible claspers). Water depth at this location is 190 fms. and water temperature was 67.2 F.

#15	19 Oct. 2001	California	M	~5.5 FL			On October 19, 2001, another Megamouth shark (male, approx. 18 ft. fork length) was caught in a drift gillnet and released alive in good condition. A U.S. National Marine Fisheries Service observer was aboard the commercial swordfish vessel, approx. 42 miles northwest of San Diego, California. The observer was able to collect a tissue biopsy and take many color photographs including one of the upper jaw with white lip and lower jaw with dark spots on a white chin. The observer also noted the presence of claspers. Water depth at this location is 460 fms. and the sea surface temperature was 65.8 F. This is the fourth (November 1984, October 1990, October 1999) Megamouth shark caught off Southern California in a drift gillnet targeting swordfish.

#17	20 Apr 2002	Natures Valley, Western Cape Province, South Africa (33^o 59' S, 23^o 34'E)	F	~4			On 20 April 2002, a large shark was stranded at Natures Valley (33o 59' S, 23o 34'E) in the Western Cape Province, South Africa. Initial reports suggested that it was a whale shark, but subsequent reports and digital photographs confirmed that it was a megamouth, Megachasma pelagios. Dr Vic Cockcroft of the Centre for Dolphin Studies collected it from the beach to ensure that it was not washed out to sea again. It is the first record of this species in South Africa and the Western Indian Ocean and is the 17th discovered world-wide since its discovery off Hawaii was announced in 1976. It was iced early the next morning and collected by Dr Malcolm Smale and Matt Dicken and brought back to the Port Elizabeth Museum. It was placed in a scientific freezer and frozen to -20o C. A preliminary examination showed that the animal, approximately 4m long and female was in reasonable condition, but the skin was scuffed and there was some damage to the fins. It will be examined, measured and dissected by Drs Malcolm Smale (Port Elizabeth Museum) & Leonard Compagno (South African Museum) in early May. Various samples, including tissues for DNA analyses will be saved for future research. Taxidermists will make a mould of the animal for educational displays in museums. Elasmo-L posting by M.

#33	05 June 2005	Hualien, Eastern Taiwan	M	~3.5-4.0	400-500		The fishermen in Hualien got another megamouth...I guess it's #33? Because it was Sunday and the fishery office isn't open, length and weight were not taken at the dock buy according to the dealer the weight was 400~500kg and closer to 500kg. . I have asked the fisherman to save some vertebra and muscle tissue for me. There was an earthquake the day before, and this megamouth shows up. Just like last time. according to the dealer is 400~500kg and closer to 500kaccording to the dealer is 400~500kg. This shark was in bad shape when Victor Lin rushed to the dock two days after capture. The tail was broken when hung onto the boat. The first half was about 1.75 m and tail end about 178cm . The whole right upper jaw was gone. It probably "slipped" into the sea when they hooked the shark and broke the jaw.

Megamouth Shark #27 Captured In Purse Seine off Japan
Sources of Information: Masami Furuta Toba Aquarium
A megamouth shark was captured with a purse seine set off the coast of Kiseicho Nishiki, Mie, Japan. The purse seine was set at a depth of 200 meters around 5:00am on January 23, 2005. We received a phone call informing us of the possible catch of a megamouth shark. We went to the fishing port but by the time we arrived, the megamouth was already dead. This megamouth was a female with a body length of 528 centimeters. The megamouth was hoisted onto a truck with the assistance of a lift and was transported to the Toba Aquarium where it was placed in a freezer. In the near future, we will taxidermy this animal for display at the aquarium.

The fishermen in Hualien got another megamouth...I guess it's #33? Because it was Sunday and the fishery office isn't open, length and weight were not taken at the dock buy according to the dealer the weight was 400~500kg and closer to 500kg. . I have asked the fisherman to save some vertebra and muscle tissue for me. There was an earthquake the day before, and this megamouth shows up. Just like last time. according to the dealer is 400~500kg and closer to 500kaccording to the dealer is 400~500kg.

This shark was in bad shape when Victor Lin rushed to the dock two days after capture. The tail was broken when hung onto the boat. The first half was about 1.75 m and tail end about 178cm . The whole right upper jaw was gone. It probably "slipped" into the sea when they hooked the shark and broke the jaw.

The only information I was able to collect for this megamouth is its weight and capture date (200 kg+; around June 30). No length, sex, photo, nor other data. The fisherman (dealer) who reported it to me was the same one who bought the #33 megamouth, so I believe it to be authentic. Victor Lin personal communication.
