At least four species of crocodiles are able to climb trees, according to 2014 research by the University of Tennessee. Although the large reptiles are known for staying mostly in or near water, American crocodiles, Australian freshwater crocodiles, Central African slender-snouted crocodiles, and Nile crocodiles were all observed climbing trees. Smaller crocodiles, or those less than 6.5 feet (2 m) long, were the most common climbers. However, they tend to not venture up trees when they know they are under surveillance. Researchers believe crocodiles climb trees to regulate their body temperatures, as well as to look out for possible threats from predators.
