Bioluminescence is, by it’s definition, emitted light from living things. It serves several purposes in life, including warnings to others, attracting food, and attracting mates. We know that a good many things have glowy bits, but it’s hard to get a good idea of just how many things around us can create their own light. Now we finally have a very pretty chart, courtesy of artist Eleanor Lutz, that details a (non-exhaustive) number of luminous species. It’s a lot more than you’d think. Check it out.
