Terrapins are friends, not food!
Why do we call them terrapins and not turtles?
Terrapins are a type of turtle. They can live in freshwater like some other turtles BUT can also live in salt water, too. This type of mix of salty and fresh water is called brackish waters. Other types of turtles could not survive where the Diamondback Terrapins thrive.
Why are they called "Diamondback" Terrapins?
The shell or carapace of the terrapin has diamond shaped sections also called scutes. The rings of the scutes can help indicate the age of the terrapin. See the image to the left of a female terrapin's carapace.
