Iguanas spend most of their time in trees. A lizard this large looks like it should be lumbering along the ground, and iguanas are often seen on the ground. In fact, in Tamarindo I have seen iguanas walking along beside the sidewalk right in the middle of town.
There are 38 species of iguanas in Costa Rica. This is a green iguana, also called a common iguana. In Spanish it is a garrobo, and its scientific name is the redundant iguana iguana.
Green iguanas reach 2 meters (6.5 feet) in length and they will climb as high as 20 m. (65 ft.) in trees. As adults, they eat leaves, twigs and fruit, but adolescent iguanas prefer insects. They walk very slowly, but if they are threatened and they are on a branch above a river, they can drop down into the river and swim away underwater.
