Common or Green Iguana
Out of eleven species in the family Iguanidae, the green iguana (Iguana iguana) is the most common iguana in the pet trade. Green iguanas are native to Central and South America, ranging from Mexico to Brazil. In the wild, they live in trees, basking in the sun, and only come down to the ground when females dig burrows to lay eggs.
Iguanas can grow to over 5 feet long and weigh up to 11 pounds. They have very specific care requirements and can live 10 to 15 years in captivity. Green iguanas can be quite aggressive and are not suitable for inexperienced reptile pet owners.
