Answer 1

Instead of relying on their sense of sight for night-time vision, bats make rapid high-pitched squeaks called "ultrasounds". These sounds are too high for most people to hear. If these sounds hit something, they bounce back -- sort of like when you hear your echo in a mountain or a bathroom when you shout. The bat hears the echo and can tell where the object is. This is called "echolocation". Bats have the best hearing of all land mammals. They often have huge ears compared to the rest of the body.

Smell. Smell is a dog's most prominent sense and the one that is the most different from ours. It has been estimated that a dog's sense of smell is 100,000 times more powerful than a human's. Scientists think that dogs have about 2 billion olfactory receptors—many, many more than our 40 million.
