Clown Anemonefish

The movie "Finding Nemo" made the clown anemonefish one of the most well-known fish around. The clown anemonefish or clownfish can be found in the Indian Ocean, the Read Sea, and the western Pacific where they make their homes in sea anemones that reside in shallow water. These fish are able to avoid the lethal sting of sea anemones because their skin is covered with a protective layer of mucus. Clownfish do a complex dance with their sea anemone that allows them to adapt to their host in a gentle manner. Clown anemonefish are protected from predators in their sea anemone homes and even feed off the food scraps left behind on the anemone's tentacles. In exchange for a safe home, these fish remove parasites from the anemones and scare away predators.
Moon Jellyfish

Moon jellyfish can be found in the Atlantic, Pacific, and Indian Oceans where they prefer warm, tropical waters with low salt content. Moon jellyfish are very fragile and delicate creatures who use pulsation movements to stay near the surface of the water. These animals move in a horizontal pattern with their bell-shaped upper region near the surface at all times. This allows the tentacles of the moon jellyfish to cover a larger range of space to catch food. These exotic marine creatures feed on zooplankton, mollusks, crustaceans, and other small aquatic organisms.
