When most people envision crocodiles, they think of them waddling on the ground or wading in water—not climbing trees. However, a University of Tennessee, Knoxville, study has found that the reptiles can climb trees as far as the crowns.
Vladimir Dinets, a research assistant professor in the Department of Psychology, is the first to thoroughly study the tree-climbing and -basking behavior.
Dinets and his colleagues observed crocodile species on three continents—Australia, Africa and North America—and examined previous studies and anecdotal observations. They found that four species climbed trees—usually above water—but how far they ventured upward and outward varied by their sizes. The smaller crocodiles were able to climb higher and further than the larger ones. Some species were observed climbing as far as four meters high in a tree and five meters down a branch.
