Ok so sometimes you find random things while your on the internet (it really is all too easy)..........yes I was revisiting my childish interest in world mysteries - what of it??
HISTORY:- 'On April 25, 1977, a fishing vessel named the Zuiyo-maru of the Taiyo Fishery Company Ltd. was trawling for mackerel about 30 miles east of
Christchurch, New Zealand, when a large animal carcass became entangled in its nets at a depth of about 300 meters (almost 1000 feet). As the massive creature, weighing about 4000 pounds, was drawn toward the ship and then hoisted above the deck, assistant production manager Michihiko Yano announced to the captain (Akira Tanaka), "It's a rotten whale!" However, as Yano got a better look at the creature, he became less sure. About 17 other crew members also saw the carcass, some of whom speculated that it might be a giant turtle with the shell peeled off. However, no one on board could say for sure what it was (Aldrich 1977; Koster 1977)..........
Despite the possible scientific significance of the find, the captain and crew agreed that the foul-smelling corpse should be thrown overboard to avoid spoiling the fish catch. However, as the slimy carcass was being maneuvered over the ship in preparation for disposal, it slipped from its ropes and fell suddenly onto the deck. This allowed the 39 year old Yano, a graduate of Yamaguchi Oceanological high school, to examine the creature more closely. Although he was still unable to identify the animal, Yano felt it was definitely unusual, prompting him to take a set of measurements, along with five photographs using a camera borrowed from a shipmate. The total length of the carcass measured 10 meters (about 33 feet). Yano also removed 42 pieces of "horny fiber" from an anterior fin, in hopes of aiding future identification efforts. The creature was then released over the side and sank back into its watery grave.........
SEA MONSTER
( Some carcass pics from the 70's...... ) On July 20, 1977, as excitement and speculation about the find began to spread, officials from the fish company held a press conference to publicly announce their mysterious discovery. Although scientific analysis of the tissue samples and other data had not yet been completed, company representatives played up the sea-monster angle.
Dozens of fishing vessels from Japan, Russia, and Korea were reportedly streaming toward New Zealand in hopes of resnagging the hastily discarded creature. With so much 'Monster Mania' the Japanese government even decided to issue a postage stamp (issued Nov. 2, 1977) of the sea-serpent.
STAMP
CONCLUSION:- Several lines of evidence strongly indicate that the Zuiyo-maru carcass was a large shark, and most likely a basking shark, rather than a plesiosaur......'
