Moon jellies are translucent, appearing almost colorless with a delicate shimmer that makes them look like they are glowing. They have a saucer-like shape with short tentacles hanging down in a fringe along the edge of their bell. These jellyfish have a gentle pulsing movement as they drift through the water.
Jellyfish come in many different sizes. Many are small and can fit in the palm of your hand. Others are much larger than humans.

The jellyfish is translucent, usually about 25-40 cm (10-16 in) in diameter, and can be recognized by its four horseshoe-shaped gonads, easily seen through the top of the bell.
In Tunisia, several types of jellyfish can be found, including the common moon jellyfish (Aurelia aurita) and the lion's mane jellyfish (Cyanea capillata). The moon jellyfish is characterized by its translucent, umbrella-shaped bell, while the lion's mane jellyfish is known for its long, trailing tentacles. Other species may also be present in Tunisian waters, particularly during the warmer months when jellyfish blooms occur. These jellyfish are significant to the marine ecosystem but can also pose risks to swimmers.
