She weighs almost three tons. The carcass of a dead moon-fish weighing 2,744 kilograms was caught off the coast of the Azores - this is an absolute record for bony fish. Its height is 3.5 meters, and its length is 3.6. Marine biologists weighed the moon fish using a winch and industrial scales, and then opened it up. They took samples of DNA and stomach contents. Moon-fish lives in tropical and temperate waters of all oceans. Their exact number is unknown. In spring and summer, the population in the northwest Atlantic is estimated at 18,000 individuals.
