An egg laying mammal with webbed feet and a bill like duck?

You're describing a platypus!

These fascinating creatures are native to eastern Australia, and they are truly unique. They are one of only five species of monotremes (mammals that lay eggs), and their unique combination of features sets them apart:

* Egg-laying: Like birds and reptiles, platypuses lay eggs.

* Webbed feet: They use their webbed feet for swimming and paddling.

* Duck-like bill: Their bill is sensitive to electrical signals, allowing them to locate prey underwater.
