You'd think with all those arms they'd have at least one free to focus and set the exposure. This is a picture taken by an octopus who stole a divers' camera.
The diver chased it and got the camera back. Otherwise, we'd be waiting for the octopus to get online and upload the pictures to youtube.

I got an email from the head of this study, David F. Colvard, MD, of Raleigh, North Carolina. His team has shown that nasal irrigation can help solve a common problem for scuba divers: middle ear squeeze.
Great idea, but don't do what these guys did.
Five SCUBA divers from Euope went diving in the vicinity of Indonesia in waters known to be very treacherous.
They quickly became separated from their boat, and floated in shark infested waters for two days.
I am surprised at how many people (chemistry faculty included) have never seen this demo. (oh, technically it is called a cartesian diver demo) Basically, you put some floating object that has an air space in a closed bottle of water. When you squeeze it, the diver goes down.
