Captive iguanas often live to be 10-12 years old. There are reports of them having lived past 20 years in captivity. Only about a third of the iguanas sold in pet stores survive to maturity because of importation stress, improper diet, temperature and sunlight. In the wild, the number is even lower because the babies are finger-food for a number of jungle predators.
A herd of about 40 giraffes is mostly composed of females and calves with several bulls, or male giraffes mixed in. The young male giraffes move together with the older males and are more solitary and love to live alone. While in captivity, a giraffe can live for about 28 years or even longer. Many giraffes do not make it into adulthood because more than half of all calves are killed by hyenas, lions, and other predators within the first year after birth.
