What is a green ameiva's habitat?

The forests and savannah of the Amazon and Brazil are where these lizards thrive. Rainforest that has been newly harvested is their most desirable habitat. Their rate of reproduction also depends on their habitat and the amount of rainfall. Lizards that inhabit areas which receive incessant rainfall throughout the year yield more eggs than those lizards who exist in places where rainfall is seasonal. This means that breeding is also seasonal.

The method of reproduction of this species is based on the observation of the reproduction process of the Caribbean Ameiva because of inadequate data. When lizards attain sexual maturity at eight months of age for both males and females, the males exhibit the disposition of safeguarding the females during copulation.

The gestation period is five months and the eggs are laid in clutches. The size of eggs varies according to the region. The female lays approximately six to 11 eggs, and females who are typically larger have a bigger clutch size than smaller females. Females can lay up to three clutches every cycle.
