They contain no carbohydrates. No fats. No proteins. Not much else but water. Still, the moon jelly (Aurelia aurita) are eaten by predators in the sea; fish, crustaceans, sea anemones and even corals and turtles.

Now a new study may explain why these predators bother to eat the gelatinous creatures. The study is based on moon jelly samples from a German Fjord.

– The jellyfish in our study showed to contain some fatty acids that are very valuable for their predators. Fatty acids are vital components of cell membranes and play a crucial role in processes like growth and reproduction, says marine biologist and jellyfish expert, Jamileh Javidpour from University of Southern Denmark.
