Adaptation of an Animal

DSC_0162

Waterfowl (including ducks such as the one shown here) as well as semiaquatic mammals such as otters, beavers, and platypuses, have all evolved webbed feet as an adaptation to the water. Webbed feet provide these animals with thrust and lift to propel them through the water efficiently. The feet of some ducks are capable of changing color during different seasons as to better blend in with their surroundings. In most waterfowl, webbed feet also assist with flight.
