Zuiyo-maru carcass
The Zuiyo-maru carcass (ニューネッシー, Nyū Nesshii; literally "New Nessie") was a corpse, caught by the Japanese fishing trawler Zuiyō Maru (瑞洋丸) off the coast of New Zealand in 1977. The carcass's peculiar appearance resulted in speculation that it might be the remains of a sea serpent or prehistoric plesiosaur.
