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 South American ground lizard is also kept as a pet and when in captivity, they make tunnels under rock or logs if provided with adequate soil. In the wild, they dwell under leaf litter, logs, and often seek shelter on the forest floor. They are non-territorial but have a home range.
