Friday Fun: Gross Out!

A housefly will eat almost anything. If the food is liquid, the fly just sucks it up. But if it’s solid, things get a bit more complicated. After all, a fly doesn’t have teeth.

The fly ejects a mix of saliva and digestive juices from its stomach. The vomit breaks down food from the outside in. Then the fly mops up the meal with its sponge-like mouthparts. That’s something to think about the next time you see a fly on your food.
