And, this provides us with an opportunity to expose hidden colors that we wouldn't normally see. And by the way, I should add that fluorescence usually goes hand in hand with night photography. And so, let's talk a little bit about biofluorescence. Some animals fluoresce underwater, and examples include zooxanthellae, which are microscopic organisms that live in corals, as well as certain algae, and a bunch of other animals that we'll be showing you in just a moment.
