The duck's webbed feet aid in its ability to navigate bodies of water. The webbed feet allow the animal to swim easily and quickly.
There are not any nerves in the duck's webbed feet. Therefore, they cannot feel the cold and have the ability to be in the water during cold weather.
Although the webbed feet allow them maneuver in the water with ease, they do slow them down on land. This type of foot causes the animal to waddle when it walks.
The duck is also covered in waterproof feathers, which also protect the animal from icy water. The duck produces an oil that it applies on its feathers.
