where did the green iguana originally come from
Green iguana The green iguana (Iguana iguana), also known as the American iguana, is a large, arboreal, mostly herbivorous species of lizard of the genus Iguana. It is native to Central, South America, and the Caribbean. Usually, this animal is simply called the iguana. The green iguana ranges over a large geographic area, from southern Brazil and Paraguay as far north as Mexico and the Caribbean islands. They have been introduced from South America to Puerto Rico and are very common throughout the island, where they are colloquially known as gallina de palo and considered an invasive species; in the United States feral populations also exist in South Florida (including the Florida Keys), Hawaii, the U.S. Virgin Islands and the Rio Grande Valley of Texas.[2][3]
Flag of Mexico Red, white, and green are the colors of the national liberation army in Mexico. The central emblem is the Mexican coat of arms, based on the Aztec symbol for Tenochtitlan (now Mexico City), the center of the Aztec empire. It recalls the legend of an eagle sitting on a cactus while devouring a serpent that signaled to the Aztecs where to found their city, Tenochtitlan.[1] A ribbon in the national colors is at the bottom of the coat of arms. Throughout history, the flag has changed several times, as the design of the coat of arms and the length-width ratios of the flag have been modified. However, the coat of arms has had the same features throughout: an eagle, holding a serpent in its talon, is perched on top of a prickly pear cactus; the cactus is situated on a rock that rises above a lake. The coat of arms is derived from an Aztec legend that their gods told them to build a city where they spot an eagle on a nopal eating a serpent, which is now Mexico City.
