Today I learned about estuaries. Estuaries are places where salt water meets fresh water. There are many organisms that live in estuaries such as oysters and clams. These organisms clean the estuaries and filter out the dirty water.

I also learned that oysters filter water, one adult oyster can filter about 50 gallons of water per day.

Oysters are filter-feeders. That means they suck in the water around them, filtering out the plankton and bits of dead animals and waste that they eat, then spit the water back out, free of that waste. The process feeds the oysters, produces food for humans, and cleans the water around them.

Exactly how much these oysters clean the water, though- that was something that I'd never seen illustrated in a clear, concise, this vs. that sort of way. Until yesterday, that is, when someone forwarded me the following picture:

That's a pretty compelling picture, originally posted to Reddit by username NoSpicyFood, and followed up with comments about Eastern oysters cleaning up to 50 gallons of water per day. Each.

It's good stuff, in other words. Take a look at the picture, head on over to Wikipedia to learn more about the Eastern oyster, then let us know what you think of the little guys' work in the comments section at the bottom of the page.
