Diamondback terrapin

This turtle was at the Fernbank Museum of Natural History in Atlanta. It may be the only turtle that lives solely in brackish water as most species also spend time in either oceans or freshwater. Because of their limited habitat they have developed some special ways to get fresh water. During rainstorms they drink the thin top layer of rain firming on saltwater, and also catch raindrops in their mouths. I find this fun for a minute or so but not as my primary source of water. Then again, I also don’t spend all my time in briny water.
