That's not entirely true, otherwise the "turtle races" would be illegal. Yes, I have looked it up. You can possess 1 of the following without a permit, though other than that, if it's native to MD, you're right, it is illegal:
Wood Turtle
Spotted Turtle
Eastern Box Turtle
For the full disclosure, including the minimum size requirement here's the link:

I don't care how you feel. Live and let live- tree hugger or otherwise. But if you're going to give information, especially something that can be easily researched, make sure it's right or at least add a simple "IIRC."
*Disclaimer* The above is in reference to turtles only since this is a turtle thread; eventhough Ink posted about ALL animals. The link does provide for information on other herps. I don't know what the law is for other animals, nor am I going to pretend to. I'm sure it should be relatively easy to find.
