What happens when you turn a starfish upside down? This nine-legged starfish couldn't have been too happy about the experiment, but he had a good recovery plan. -via Bits and Pieces
Sounds like that diver is skip breathing. http://www.scuba-doc.com/CO2retention.html
Man, I feel weird. For some reason that made me angry. Like it was animal cruelty or something. I don't even usually care but it makes me wish some alien would put them those humans in space just to see what would happen.
It's not like starfish never get turned upside down without human interference. The starfish was not hurt in any way, just purposely placed in a position it's probably been in plenty of times before. I find it amazing and intriguing how animals adapt.
I am glad the hand of that diver came in the picture, otherwise that animal just as well could have been only some inches or several tens of feet in size like the stuff of nightmares...
I think I need to chill out.
