Cuban treefrog - The Cuban treefrog ranges in size from 3 to 5.5 inches in length. They may be white, gray, tan, green, or brown in color, and can change colors depending on their temperature and environment. Many individuals have darker splotches on the back, and some splotchy banding on the legs. In many individuals, the hidden surfaces of the legs are bright yellow. When the frog leaps to avoid a predator, these bright yellow patches are visible, and may help to confuse the predator. In Florida, the Cuban treefrog is the largest of all the treefrogs. These large frogs have somewhat bumpy, warty skin, and their toepads are much larger than those of native treefrogs. Also, the skin on their heads is fused to the skull—if the head of an adult frog is rubbed , the skin does not move. This is a special adaptation that prevents water loss, since there are fewer blood vessels in the "co-ossified" area. When handled, Cuban tree frogs secrete a toxic mucus from their skin in humans, this can cause an allergic reaction or burni
