Jellyfish in the Mountains?

This is not the normal wildlife of the Southern Appalachian, but that is where I found these strange creatures. Before you call the University of Tennessee to report a new species in the mountains, I must confess I got this picture at Ripley's Aquarium in Gatlinburg Tennessee. I set the camera at 400 ISO to take advantage of the existing light. When shooting through glass it is always better to avoid flash photography. Setting the camera on a higher ISO enabled me to set a fast enough shutter speed to stop the movement of the jellyfish. LynnFreeny.com
