The megamouth shark (Megachasma pelagios) is one of the worlds rarest sharks – spotted only 43 times since its discovery back in 1976 off Oahu, Hawaii. These sharks are huge and bizzare creatures, capable of growing upwards of 5m in length, with luminescent light organs surrounding the mouth to attract plankton and small fish. So rare is the megamouth shark, that apparently scientists were surprised to find the 44th megamouth shark (caught by mackeral fishers in the Phillipines) had been cooked and eaten by local villagers before anyone could take a closer look. I wonder which part of the 500 kilogram shark was considered the delicacy? Read more at the National Geographic – thanks to Brian for the tip!
