Description
Ear Jellyfish
The ear jellyfish, also known as Aurelia Aurita, is the most common jellyfish found in jellyfish aquariums because it is very easy to keep and is not toxic to humans (detailed
instructions
for jellyfish keeping can be found in our instructions section).
The ear jellyfish belongs to the class of umbrella jellyfish, also called Scyphozoa, within which cnidarians are called Cnidaria. This jellyfish species is distributed almost worldwide in all seas from about 70° North to about 55° South.
It also occurs on the German North Sea coast and in the western part of the Baltic Sea coast. The living conditions here are still ideal for them due to the salt content of the water.
Their umbrella is flat curved and can grow up to 30 centimetres in the sea. Within the umbrella are the four ring-shaped genitals of the ear jellyfish.
Ear jellyfish move through the pulsating movements of the jellyfish umbrella. Through these gentle and relaxing movements the jellyfish floats through the aquarium. It therefore pushes water downwards by this contracting movement through the recoil principle.
With this technique, ear jellyfish can travel up to ten kilometres per hour. In most cases they simply let themselves drift with the current. Nevertheless, jellyfish need a regular current in which they can drift for survival.
As ear jellyfish are almost transparent, they adapt to the colours of your LED lighting, creating a fascinating and unique sight.
Our jellyfish are very young to be able to live and grow in your aquarium as long as possible.
This jellyfish species is suitable for jellyfish aquariums of any size.
