“Super-natural” senses aren't magic—they're just senses humans have not developed. For example, we can't sense changes in another creature's body heat. But some snakes can. We can't sense forces of electricity that come from living things. But some fish can. We can't sense the pull of Earth's magnetic field. But some birds and other animals can. Bats use echolocation to “see” objects around them as they fly. Scientists have a lot to learn about how animals use these and other senses.
