Moon jellyfish primarily eat planktonic crustaceans, but they also eat other small plankton including molluscs, fish eggs and smaller jellyfish. They catch their food with sticky mucus that lines the underside of their bells and then direct it into their four stomach pouches with their tentacles.Continue Reading
Moon jellyfish possess stinging cells like other jellyfish, but they primarily use them to deter predators rather than capture prey. Their tentacles are not long and trailing like those generally associated with jellyfish, but instead form a fine fringe along their bell margins. Their specific anatomical features vary by location, with populations occurring on the Pacific coast from San Diego, Calif., to Prince William Sound in Alaska.
Their primary predators are birds, turtles and the much larger lion's mane jellyfish. Moon jellyfish are not hunted by humans, but some are captured for the pet trade and public aquariums. Despite these threats, moon jellyfish are extremely abundant, and their populations are not threatened. In the wild, moon jellyfish appear in very large groups of hundreds of millions of individuals. This is likely coincidental in their habitats, because no known form of communication occurs between these very simple animals. They spawn in these large groups via internal fertilization.Learn more about Jellyfish
Types of jellyfish in Florida include the moon jellyfish, the cannonball jellyfish, the sea nettle and the box jellyfish. Other jellyfish include the mushroom jelly. The Portuguese man-of-war isn't really a jellyfish, but looks and stings like one.Full Answer >
Jellyfish are not actually fish, but a collection of plankton. Though relatively simple, they are able to survive without the presence of a complex circulatory, digestive or central nervous system.Full Answer >
Jellyfish primarily eat plankton, which are organisms that lack the strength and size to swim and therefore drift in marine and freshwater currents. Larger species of jellyfish also eat crustaceans, fish and other jellyfish. Jellyfish are carnivorous and primarily feed on animals. Some jellyfish have tissue containing symbiotic algae, which enables them to receive energy through photosynthesis.Full Answer >
Box jellyfish eat shrimp, fish and worms by using their tentacles to sting prey and then pulling the prey into their mouths. Many species of jellyfish eat their prey in this manner.Full Answer >
