The noticeable adaptation of an animal to its aquatic habitat is the possession of webbed digits. Webbed digits are the fusion of the toes of an animal, giving them a wider surface area to help them swim through the water more efficiently. Animals that live in aquatic environments, such as ducks and otters, have webbed digits that allow them to swim and navigate through their habitats with greater ease. This adaptation is an example of how animals can evolve to better suit their environments and improve their chances of survival.
