Happy World Krill Day! If you didn't know, krill are tiny marine crustaceans found in oceans worldwide. Their name comes from the Norwegian word for "small fry of fish." Though small, krill play a very important part in maintaining ecosystems. As a keystone species, they provide an essential food source for many animals. Not only do whales rely on krill, but many invertebrates do as well! At Butterfly Pavilion, our Sea Stars, Horseshoe Crabs, Spider Crabs, and Mantis Shrimp all enjoy krill as part of their diet. #WorldKrillDay #Krill #Invertebrates #ButterflyPavilion #CultureForAll
