Aye ayes are lemur-like primates found along the east coast of Madagascar. They eat berries, eggs, bamboo, and small fruits and nuts. Aye ayes can grow up to 3 feet long and weigh 4-6 pounds. In the wild they live about 10 years, but in captivity they can live up to 23 years. They mate once a year with a different partner each time and males can get aggressive during mating season.
