Comb jellies, also known as ctenophores, have rows of comb-like plates that they use for locomotion. As they swim, the combs refract light and have a glowing rainbow effect. Some species are bioluminescent, meaning that they can produce their own light and flash on and off when disturbed.
Guess what else they sometimes do when disturbed?
