I was surprised at how much I enjoyed myself at the aquarium in Genova (Italy). The first five photos are all of various sea life (and a couple of people) "hanging out".
Jellyfish hanging out. I was mesmerized by all of the amazing jellyfish displays. Here are photos from two of the displays.
A seal hanging out at the top of the tank. He or she hung out there for quite a while, then swam around a bit, and then returned to the exact same spot once again.
A shark hanging out, possibly watching lunch swim by?
A mom with her son watching more sharks hang out.
Nearby the aquarium in Genova, I found more examples of "hanging".
To the right of the aquarium, two statues hanging off of a ship.
And to the left of the aquarium a strange hanging thing that people seemed to be paying to go inside and take a ride up a few feet in the air. I didn't really understand the purpose of this other than to get a view from up high. I did not inquire about the cost.
