10 Things You Didn’t Know About How Animals See the World

8. Echolocation – Seeing with Sound

While not a visual sense in the traditional sense, echolocation is a form of perception that allows animals like bats and dolphins to "see" their environment using sound. By emitting calls and listening for the returning echoes, these animals can construct a detailed mental map of their surroundings, identifying objects, prey, and obstacles. This ability is particularly useful in environments where vision is limited, such as dark caves or murky waters. Echolocation demonstrates the remarkable plasticity of sensory systems, where the boundaries between different types of perception blur, creating new ways of experiencing the world.
