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 for a sea anemone, 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. (x)

Upside-down jellyfish (Cassiopea andromeda)

The 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 for a sea anemone, 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. It is carnivorous and eats small animals from the sea or just pieces of them after it paralyzes its prey with its mucous and nematocysts when they are released. This jellyfish also lives in a symbiotic relationship with photosynthetic dinoflagellate algae (like seen in the last picture), the Zooxanthellae, and with shrimps. This jellyfish can measure the maximum of 30.0 cm wide. The jelly can sting which makes it important to take precautions when around it. Symptoms include pain, rash, swelling and vomiting.
