New research has revealed how Crocodiles are able to eat snakes, buffalo, cattle and even people and digest them.

The secret behind it is a heart valve that crocs control neurologically, which lets blood bypass the lungs and flow through a special aorta straight to the stomach, enabling them to secrete gastric acid at rates 10 times faster than those measured in any other animal.

Crocodiles, alligators and other crocodilians all share this ability, said biologist C. G. Farmer at the University of Utah, who discovered the connection between the heart valve and digestion in research that will be detailed in the March-April issue of the journal Physiological and Biochemical Zoology.

Your fun fact of the day: Did you know that crocs can eat 23 percent of their body weight at once? That would mean that a 180 pound man could eat a 40-pound hamburger in one sitting.

Yeah, I wouldn't want to see that at the local casino buffet line...
