Webbed feet are a type of foot structure where the toes are connected by a membrane or skin. This adaptation is commonly found in aquatic animals like ducks, frogs, and otters, allowing them to swim more efficiently. The webbing acts like a paddle, helping these animals push through water with less effort. In addition to aiding in swimming, webbed feet can also provide stability on soft or muddy surfaces. Some birds, such as geese and swans, use their webbed feet for both swimming and walking. This unique feature enhances their ability to thrive in various environments.
