There are animals who are known to live longer than that - a certain species of jellyfish is known not to age, and there are examples of animals which are known to be older than any human has ever been confirmed to be. It's a difficult question to answer though, why we live longer than most things animals.
Anolis, or anoles, is a genus of iguanian lizards belonging to the family Dactyloidae. With 391 species, Anolis represents the world's most species-rich amniote tetrapod genus. Previously, it was classified under the invalid family Polychrotidae that contained all the anoles including Polychrus, but recent studies place it under Dactyloidae.
Anolis carolinensis varies in length from 4 to 8 cm. Females typically are smaller in all body size measures, at birth ranging from about 23 to 25 mm long. Both males and females have long tails that account for more than half of their total body lengths. Adult anoles weigh between 2 and 6 g.
