Columbus' serpent was a cryptid reported from Crooked Island in what is now The Bahamas in 1492. On 21 October of that year, some men under Christopher Columbus' killed a 5 foot long "snake" which was living in a freshwater lagoon. Martin Alonso Pinzón of the Pinta killed another the next day, and planned to skin it, but never did.
It was long thought to have been an iguana instead of a snake, but these lizards rarely enter water, and are not known from the island, even in fossil form. Excavations at a village on the island visited by Columbus later found the femur of an American crocodile.
