Dolphins never cease to amaze me. I just found this video,  shot at Sea World in Florida, of several dolphins creating rings made out of air bubbles. I can't even comprehend how they actually get the rings to float so long and then break them into different sizes.

It is hypnotic. You have to watch it a couple of times to appreciate just how ingeniously playful these creatures are.

Scientists have been studying dolphin antics in the Gulf of Mexico (where dolphins are most abundant) to learn more about their behavior and biology. If you want to learn more, check out the recent report by the Institute of Marine Mammal Studies in Gulfport.

It's also dolphin-watching season this month in Baja. Check out this video of a wild dolphin "stampede."
