Giant Ameiva
Panama, forests near Panama City (2007).
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 specs and mottling along the sides. Females usually have much less green than males and a more dusty of a green color. Males have vibrant green coloration and more bold mottling. Males also have more expanded jowls. Green ameivas are popular as a pet because of the male's striking green coloration. I guess this one is a female.

The giant ameiva, also known as green ameiva, South American ground lizard, giant whiptail, zandoli, and Amazon racerunner, is a species of lizard in the family Teiidae found in Central and South America and some Caribbean Islands.
