Biology

Moon Jellyfish females carry groups of developing young on their arms. They are sought after for display in aquariums. The species in Victoria was thought to be the same as one found all over the world, Aurelia aurita, however DNA testing revealed that our Moon Jellyfish may actually be at least 7 different species.
