The More You Know: Wait, what about those gonads?
Individual Jellyfish are either male or female. The eggs and sperm develop in very colourful special areas called 'Gonads' inside the body wall. When all of the eggs and sperm are fully developed, they are released into the stomach and then through the mouth into the sea. In most cases, to reproduce, a male jellyfish releases his sperm into the surrounding water. The sperm then swims into the mouth of the female jellyfish, allowing the fertilization of the ova process to begin.WHAT!
