Are they from another planet? Well, no, just from a part of our own planet that few see. Monterey? Oh, no, sorry, I meant under the great oceans. This particular one was, however, in the aquarium at Monterey. Part of a spectacular section of the aquarium devoted to jelly fish.
Many people are familiar with the orange on blue jelly fish photos that have become a signature image for the Monterey Bay Aquarium, but there are many other species at the aquarium too from ghostly white saucers to jellies that could be mistaken for plants.
