Animals have a variety of senses that help them interact with their environment. Most animals rely on the five basic senses: sight, hearing, touch, taste, and smell. However, some species have developed unique senses. For example, bats use echolocation to navigate and find food in the dark, while sharks can detect electrical fields produced by other animals. Different animals also have varying levels of sensitivity in their senses. Dogs have a highly developed sense of smell, allowing them to detect scents at incredibly low concentrations. In contrast, birds often have excellent vision, enabling them to see a wider range of colors than humans can.
