Animals can sense their environemnts in amazing ways. These senses help animals to make important decisions for survival. Many animals have unique senses. Some have excellent night vision. Others can hear extremely quiet sounds.
Bats can navigate and find prey in darkness. To do this they use echolocation. With this sense, bats send out a sound and it echoes back. Birds can see colors that humans cannot. This helps them find food and identify mates. Dogs have a strong sense of small. They can use their nose to recognize people or find hidden objects. Fish can sense tiny pressure changes in water. These changes help them find food or avoid danger.
