Ameiva ameiva, also known as the giant ameiva, green ameiva, South American ground lizard, or Amazon racerunner, is a species of lizard in the family Teiidae found in Central America, South America, and some Caribbean Islands.
It is widespread in Central America and South America, including: Panama, Brazil, Colombia, Surinam, French Guiana, Guyana, Venezuela, Bolivia, Ecuador, Peru, Argentina, and Paraguay. It is also found on the Caribbean islands of Trinidad and Tobago, Grenada, the Grenadines, Barbados, Dominica, St Kitts and Nevis, Margarita, Swan Island, and Isla de la Providencia. It was also once present on Saint Vincent but has since been extirpated.
Ameiva ameiva has a streamlined body, pointed head, slightly forked tongue, and muscular hind legs. They grow to approximately 45–50 cm (18–20 in). Both sexes have random black specks and mottling along the sides. Females usually have much less green than males and a more dusty green color. Males have vibrant green coloration and more bold mottling. Males also have more expanded jowls. They are popular pets because of the male's striking green coloration.

It is the 2nd most-seen of the 22 reptiles we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
October and November
In those months about 80% of wildlife watchers report an Amazon Racerunner in Brownsberg Nature Park on a given day, against about 40% in March, the lowest month. Those are among Brownsberg Nature Park's driest months, with about 95 mm of rain a month against 490 mm in May. June and August–September have too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Amazon Racerunner sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Amazon Racerunner is recorded against all the reptiles logged in Brownsberg Nature Park (33 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
