Animals “see” electromagnetic fields

Human senses allow us access to “information” about the world outside of ourselves. Our senses are based on human evolution and the needs of being human. We can’t possibly perceive everything going on around us but we perceive the things that were relevant for our evolutionary past. The same is true for other species whose senses allow them access to other information we can’t perceive. Sometimes these senses are more acute than human senses like a dog’s sense of smell and sometimes these senses allow access to information that is inaccessible to our inborn senses.

Here are two new articles about animals that can perceive electromagnetic fields. Do they “see” them the way we see visible light? Some interesting speculation about how that might work and what it might look like.
