What mammal is perfectly suited for semi-aquatic living?

The beaver has specially created features that allow it to prosper in and out of water. The beaver is equipped with built in goggles for seeing, ear and nose valves that seal, and self-sharpening teeth for cutting trees. It also has the ability to retrieve and store food underwater, a large paddle-shaped tail to be used as a rudder to navigate through the water, and webbed duck feet for great swimming power. It is furnished with two oil glands that provide waterproofing for two layers of fur with the ability to regulate its body temperature. Couple this with its large lungs and liver, and you have a super swimmer because the beaver can store more air, thus producing extra oxygenated blood while submerged. All of the beaver’s features must be fully intact and functional from the beginning for it to survive in its surroundings. The beavers’ amazing design  is evidence for a Creator!
