Crocodilians, like crocodiles, alligators, and caimans, have a fascinating ability to change the color of their skin when exposed to certain environments. This phenomenon was first observed in the American crocodile, a ѕрeсіeѕ found in coastal regions of the southern United States, Mexico, Central America, and northern South America. Researchers noticed that when these crocodiles basked on the beach, their skin turned a much lighter color than when they were in the water or on land with a darker substrate.
