Most mature iguanas weigh between 4 and 6 kg, but some in South America, with proper diet can reach up to 8 kg. Upon hatching, the length of green iguanas ranges from 17 to 25 cm. Within three years, a young, 12 gram hatchling iguana can become a 1 kg adult (de Vosjoli, 1992). ( Alberts, et al., 2004 Campbell, 1998 Conant and Collins, 1998) No matter where they inhabit, they prefer to have water around as they are excellent swimmers and will dive beneath the water to avoid predators (Conant and Collins 1998). Although preferring an arboreal (forested) environment, they can adjust well to a more open area. This tree dwelling habit allows them to bask in the sun, rarely coming down except when females dig burrows to lay eggs. Juveniles establish areas lower in the canopies while older mature iguanas reside higher up. Green Iguanas are arboreal lizards that live high in the tree canopy. ( Campbell, 1998 Conant and Collins, 1998) This is the largest known lizard to occur within the borders of the United States (Conant and Collins, 1998 Campbell, 1998). This large lizard also inhabits many islands throughout the Caribbean region and the coastal eastern Pacific, and has been introduced into southern Florida and in Hawaii.

Green iguanas, Iguana iguana, occur throughout Central and South America, from Sinaloa and Veracruz, Mexico, south to the Tropic of Capricorn in Paraguay and southeast Brazil.
