Mediterranean jelly or fried egg jellyfish/ medusa huevo frito o del Mediterráneo.

It seems that this jellyfish's sting has very little or no effect on humans. 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.
