Its body made up of 94 percent water and gelatinous consistency has the shape of a hemispherical umbrella, on whose lower part 8 groups of 150 tentacles each are fixed. With no tentacles along the edges, the umbrella can be pink, reddish-golden, or purplish-brown. 

They edge the mouth with yellow or reddish tentacles, which form a mane. Some 8 lobes into which the body divides contain sense organs as olfactory and light receptors.
