A dozen reptile species have been recorded in the upper Pance river basin. Several Anolis lizards have been reported, also known as fan-throated lizards, as males of this group display a colorful dewlap. These lizards have also been cataloged as the "lunch boxes" of the forest, as they are eaten by many species of birds, mammals, other reptiles, and even invertebrates such as some spiders. Several species of snakes have also been found among colubrids, coral snakes, and vipers. These animals are carnivorous and play a role in population control of their prey, such as birds, frogs, small mammals, other reptiles and even other snake species. Without the snakes that now inhabit these forests, we would probably have an overpopulation of these small organisms and the ecosystem dynamics would be completely changed.
