A South American sea nettle floats ethereally in this captivating image by photographer Randy Wilder.

It is one of the many species featured in the Monterey Bay Aquarium's ongoing "Jellies Experience" exhibit.

"We grew [the sea nettles] behind the scenes from tiny ephyrae (babies)," writes the aquarium on its tumblr, "and are the first aquarium ever to display them!"
