The Mono Grande (Spanish for 'Large Monkey'), a large monkey-like creature, has been occasionally reported in South America. Such creatures are reported as being much larger than the commonly accepted new world monkeys. These accounts have received rather little publicity, and typically generated little or no interest from mainstream experts, but have received some notice in cryptozoology. Perhaps the first formal record of such creatures called 'marimondas' or 'maribundas' comes from 1533, when Pedro Cieza de Leon reported sightings from natives and from one Spanish settler. In his writings, Sir Walter Raleigh made brief note of reports of large monkey-like creatures in South America.
