Oh no, we're not talking about potato chips, deep fried chicken, or chocolate (mmm... chocolate). Some species of animals eat quite bizarre "food."

Orangutans eat soil and clay. That's rather strange. Scientists believe the primates are searching for iron in their diets, or the minerals could aid digestion for the monkeys' troubled tummies.

And some animals even eat their own poo! Japanese hares chew on grasses and shrubs, process the food, and ingest the food again to ensure maximal nutritional intake. Gross? Definitely, but also fascinating.
