A fairly obscure cryptid, the Milne is a large black bear known from only one sighting. Allegedly, in 1946, explorer Leonard Clark was floating down the Ucayali River in eastern Peru when he discovered large footprints on the bank, like those of a giant man. The next day, his canoe passed a huge black bear on the bank, clawing apart a rotted tree infested with ants. One of his crew accidentally provoked the bear, and it leaped into the water and swam towards the canoe, prompting Clark's entire crew to leap overboard and flee. Clark shot it dead, but without his crew, he was unable to retrieve it and it was devoured by piranhas (Heuvelmans, 1986; Shuker, 1997).
