An animal keeper of the Budapest Zoo feeds a moon-jellyfish (Aurelia aurita) with a syringe containing brine shrimp during an experimental program to display these extremely sensitive animals in Budapest, Hungary.

The body of the moon-jellyfish, found in tropical waters, is composed of 95 percent water and it can grow to a diameter of 40 cm (16 inch).

Keeping these animals is very difficult as their bodies are very fragile and can be harmed even by bubbles of air. Because of this sensitivity and the difficulties of reproducing oceanic conditions in the zoo, the moon-jellyfish have to be fed individually.
