This video may not be for the squeamish but it's a fascinating look into the diet of tuna off the coast of Maine.

Dr. Walt Golet at the Gulf of Maine Research Institute in Portland, was researching tuna diets and the best way to do that is find out what's in their stomach by cutting one open.

In what looks like the most disgusting magic trick ever, he pulled a whole squid out of the tuna. Ta da!
