Jellyfish are boneless animals that float throughout the world's oceans. Jellyfish can be found all over the world but are mostly found in coastal areas. Jellyfish come in all shapes and sizes, they can be from a just a few inches in diameter to over a meter. Even though Jellyfish have fish in their name they are not actually fish. They are classed in a group on their own because they are different from any other animal. They are made up of mesoglea and are surrounded by a layer of skin that is just one thick cell. The Jellyfish is mostly made up of water. Jellyfish have tentacles around their mouths that vary in length. They use these tentacles to sting or catch on to their prey. Some Jellyfish contain poison and they use this poison as a weapon to catch their prey. Jellyfish are very efficient predators.
Jellyfish mate or reproduce by the male who has reproductive organs called gonads produces the sperm, and the females produce the eggs. The male releases the sperm through its mouth and the sperm attaches to one of the female's eggs. The male sperm swims into her stomach where it fertalizes the eggs. The fertilized eggs leave the stomach and attach themselves to the female's oral arms.
