Upside-down jellyfish

Cassiopea andromeda (Upside-down jellyfish) is a type of jellyfish that usually lives in intertidal sand or mud flats, shallow lagoons, and around mangroves. This jellyfish, many times mistaken as sea anemones, usually has its mouth upward on the bottom. Its bell, which is yellow-brown with streaks and spots that are white or pale, vibrates to make the water flow through its arms for respiration and the obtaining of food.
