Creatures of the deep

They don't really seem real, resting there in the Nautilus tank at The Deep. At first I thought they might be part of a static display, they looked that artificial... then one lifted off and started drifting in the water.  I quickly turned on my camera and started filming, hoping that in the dim light I could capture some of this graceful unreal motion.  By chance, he swam under a beam of light, providing this short clip, before drifting back into darkness. 

Amazing.
