Humans navigate the world with five senses but we sometimes forget there aspects of this world we can't see, smell, feel, touch, or taste. But some creatures can sense what humans cannot. From animals like the red fox and sea turtle that use the earth's magnetism to get around, to those who can feel seismic vibrations like elephants; or snakes who hunt using the heat of another creature's body. These are the awesome animals who've been given access to inputs we humans can only imagine.
