Longest-lived lizard species

The world's longest-lived species of lizard is the Grand Cayman blue iguana Cyclura lewisi. In 1950, an adult male specimen nicknamed Godzilla was captured alive on Grand Cayman by naturalist Ira Thompson, who estimated Godzilla's age to be 15 years at that time. In 1985, Godzilla was purchased from Thompson and imported into the USA by an animal dealer, who donated him five years later in 1990 to the Gladys Porter Zoo in Brownsville, Texas. Here Godzilla remained until his death in 2004, thus yielding a period of 54 years in captivity and an estimated total lifespan of 69 years.
