Webfoot (noun)

A foot with skin that extends between the toes to form a web, typically found in aquatic birds such as ducks, geese, and swans.

Origin:

Derived from the combination of 'web' and 'foot'.

Examples:

1. The webfoot of the duck was designed for paddling in the water.
2. The webfoot allowed the bird to float more easily on the surface of the lake.
3. The webfoot also helped the bird to swim more efficiently, propelling it forward with each kick.
4. The webfoot was covered in tough, scaly skin to protect it from cuts and abrasions.
5. The webfoot was an important adaptation for the bird's aquatic lifestyle, allowing it to feed, mate, and raise its young on the water.
