What is the difference between a duck and a turtle?

Ducks are birds belonging to the Anatidae family, characterized by their webbed feet, beaks, and ability to swim. They lay eggs and have feathers for insulation. Turtles, on the other hand, are reptiles known for their hard shells, scaly skin, and ability to retract their head and limbs into their shell for protection. They lay eggs on land and have a bony shell made up of the carapace and plastron.
