There are two main ways that jellyfish reproduce and if the conditions are favourable they can do this daily. There are a few jellyfish species that receive sperm through their mouths to fertilise eggs inside the body cavity, but most jellyfish just release sperm or eggs directly into the water.

Can you raise jellyfish as pets?

The most commonly available species to be kept as a pet jellyfish are Moon Jellyfish (Aurelia Aurita). Moon Jellyfish typically live about 12 to 15 months, provided they are kept in an appropriate aquarium.

How do you breed moon jellyfish?

Moon jellyfish reproduce during two different stages in their life cycle. During the medusa stage, they reproduce sexually by releasing sperm and eggs into the water. These combine to form planula, which settle on reefs and rocks and become stationary polyps.
