Moon jelly

The moon jelly is any jellyfish of the genus Aurelia, especially A. aurita and A. labiata.

They are common to the waters off California, Japan, the East Coast of the United States, and Europe. The animal can be large (up to 15 cm across), translucent, and often considered beautiful for the patterns of organs within its body. It feeds by stinging small medusae, plankton, and mollusks with its tentacles and bringing them into its body for digestion, but is capable of only limited motion; like other jellies, it drifts with the current.
