Team mascot

J Roddy

Hello! My name is J Roddy and I am a Reeves turtle from China. How did I get my unique name you ask? I was named after a local musician named J Roddy Walston.

I am approximately forty years old and can live to sixty plus years! I was rescued from the wild animal meat market thirty years ago. Thank goodness!

I lived with Carl H. Ernst, PhD for many years. He is an author and was a Professor at George Mason University. A brilliant man with a love for turtles.

When he retired Dr. Morrison adopted me and I knew I was in good hands. Not to brag but I'm kind of a big deal around here. I love to interact with people.

Please do not tap on the glass as it bothers me. I will come to you. I enjoy treats, attention, chasing the fish, and casually soaking up the warm rays on my log.

There are lots of turtles in Maryland but remember not all of them live in water like me. If you see a turtle in the road please gently move him to the side he was headed. Do not take him home. We have a very specific home range and will spend the rest of our lives trying to get back.

For more information on turtles and how great we are visit www.matts-turtles.org.
