Fried egg jellyfish. Medusa huevo frito

Cotylorhiza tuberculata


Cotylorhiza tuberculata is a species of jellyfish, of the phylum Cnidaria, 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 40 cm in diameter[1] and is usually less than 17 cm wide. It seems that this jellyfish's sting has very little or no effect on humans. The cnidarian’s smooth, elevated central dome is surrounded by a gutter-like ring. Its marginal lappets are elongated and subrectangular. Each moutharm 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.


Mar Menor: Laguna costera de agua salada. Mar Mediterraneo. Murcia, La Manga.


Dependiendo de la estación puede ser abundante en el Mediterráneo oriental, por lo que suele ser una molestia para los bañistas, sin embargo la picadura de esta medusa tiene muy poco efecto o ninguno en el hombre.
