Relax with a Sponge

fish-spong-1Why is it relaxing to look at an underwater scene with fish and sponges? I’ve only been able to observe things like this through a sheet of glass. For those of you who have been underwater to see this type of scene, tell me. Does it feel relaxing when you are with the fish and sponges? I’m concerned I would be so nervous about not drowning that I wouldn’t appreciate what was around me. For now, I will stay on the side of the glass where I can breathe.
