Origin of the Fried Egg Jellyfish
The scientific name of this jellyfish is Cotylorhiza tuberculata. Try saying that in one go! They are also sometimes called 'Egg-Yolk Jellies'. Either way, 'Fried Egg Jellyfish' is the name that tends to stick.
Where do they live
The fried egg jellyfish is most commonly found in the Mediterranean Sea, the Aegean Sea and the Adriatic Sea. It is the most frequently encountered jellyfish species in the Mediterranean.
Description
The fried egg jellyfish spends most of its time motionless, slowly pulsing itself through the water. An adult can measure up to 35 cm across, with some individuals approaching 50 cm!
The appendages are usually a deep purple colour, resembling clusters of purple broccoli. While stingers are present, the sting has very little effect on humans - in fact, it is so mild that the tentacles sometimes provide shelter to small fish in the open ocean.
Reproduction of the Fried Egg Jellyfish
Sexual reproduction between adults takes place between August and October. The female jellyfish is internally fertilised with sperm from her partner's mouth-arm appendages. After fertilisation, she releases a large number of eggs into the water. Their life cycle lasts a maximum of one year.
Not to be missed in Malta
Usually during September, large blooms of fried egg jellyfish appear around the Maltese Islands. It is a spectacular sight and a fantastic opportunity for underwater photography. Unlike most fish, which dart away when approached, jellyfish simply drift along, making it easy to capture a great shot.
What do Fried Egg Jellyfish eat
The fried egg jellyfish feeds on small aquatic organisms, primarily plankton, phytoplankton and zooplankton. Food is taken in through the mouth-arms and travels to the stomach. One of its natural predators is the sea turtle, though turtles are rarely encountered around the Maltese Islands.
Fun facts about the Fried Egg Jellyfish
- Sometimes small animals like crabs hitch a ride on top of and inside the jellyfish's bell, tucked safely away from the stingers.
- They reproduce in warm waters, asexually producing tiny medusae (also known as baby jellies).
- Researchers think their short life cycle is an adaptation to their highly seasonal environment.
