Moon jellies are translucent, umbrella shaped marine species recognized by their four horseshoe-shaped reproductive organs easily seen through the tops of their clear bells. Capable of rather limited motion, mostly by pulsating their bell - the moon jelly's direction is dictated by the current, even when swimming. Moon jellies are typically within 10-15 inches in diameter and are found throughout most of the worlds' oceans, from the tropics to far north. Relying on a diet of mollusks, crustaceans, fish eggs and other small organisms, moon jellies feed by catching food in their tentacles or oral arms, tied with mucus, then bringing it into their body for digestion via ciliated action. Rather than breathing through respiratory parts like gills or lungs common with other marine animals, moon jellies take in oxygen from water through the thin membrane covering their bodies.
