Cotylorhiza tuberculata is a species of jellyfish, also known as the Mediterranean jelly or fried egg jellyfish. It is commonly found in the Mediterranean Sea, Aegean Sea and Adriatic Sea. It can reach 35 cm in diameter. It seems that this jellyfish's sting has very little or no effect on humans.

C. tuberculata is usually less than 17 cm wide. The smooth, elevated dome is surrounded by a gutter-like ring. The marginal lappets are elongated and subrectangular. Each mouth-arm bifurcates near its base and branches several times. In addition to some larger appendages there are many short, club-shaped ones that bear disk-like ends.[1]
