Moon jellyfish feed on planktonic organisms as well as small crustaceans.

Delicate sea beauties
On the beach, jellyfish are often considered annoying or even disgusting. However, touching a jellyfish’s slippery body is not dangerous, though it may be unpleasant. Only in a small number of species can touching jellyfish lead to serious injuries. Such encounters are rare. A special tank in the OZEANEUM allows visitors to observe just how easily and majestically these beautiful jellyfish move through the water.

Carried by a circular current, transparent, bluish jellyfish float along as if they were performing a kind of calm and elegant dance through the water. These very delicate and vulnerable animals are difficult to keep. They must remain in constant motion and the tank must be kept free of obstacles. Jellyfish are fed plankton, which they catch with their stinging cells.
Not much experience has been gathered on keeping jellyfish in aquariums because it is so difficult to build jellyfish tanks. That is why our so-called jellyfish roundabout is still in the testing phase. It will soon be upgraded to optimize the living conditions for the residents. In addition, the tank will receive a new background and a new lighting system will present the residents in an even better light.

Unlike in nature, a jellyfish’s lifespan in an aquarium is around a year since plankton is available even after autumn. When in the attractive medusa stage the jellyfish is sexually mature. They only reach an age of about 6 months in the wild. During this time, tiny larvae develop from fertilized eggs. These attach themselves to the seabed as asexual polyps from which the next generation of new medusa larvae emerges in the spring.
