RAINFOREST REPTILE TOUR: Rainforest reptiles photo slideshow

70+ pictures of reptiles in the rainforest

Reptiles are among the most common animals found in the rainforest.

Reptiles include four main groups: crocodiles and alligators (23 species), the unusual tuataras from New Zealand (2 species), snakes (about 3,000 species) and lizards (about 4,000 species), and turtles and tortoises (about 300 species).

Like frogs, reptiles are cold-blooded, meaning they generally rely on external sources of heat, rather than generating their own body heat.

Many of the world's Crocodilia species -- including alligators, crocodiles, caimans, and gharials -- live in the tropics. Every major rainforest region has at least one type of Crocodilia. These range in size from the dwarf crocodile of Central Africa to the massive, and very dangerous, saltwater crocodile of Australia and New Guinea.

Lizards are the most commonly seen reptiles in the rainforest. The largest lizards are monitor lizards of the old world, which include the Komodo Dragon from Indonesia.

Chameleons are among the world's most spectacular reptiles, capable of changing to a wide range of colors depending on their surroundings and emotional state. Roughly half the planet's chameleon species are found in Madagascar.
