This creature is called the Flower Hat Jellyfish. The name alone draws a picture! It is found off the coasts of Japan, Argentina, and Brazil. Its tentacles coil up when not in use, which makes them look like bouquets of flowers. The Flower Hat Jellyfish is just one of 14 of the most beautiful jellyfish known to man in a list from Environmental Graffiti. Link -via Dark Roasted Blend
