I found this turtle in my backyard today. It looks to me to be some kind of slider I live on the coast of south carolina if that helps any? It has yellow stripes on its head and a brown shell and the bottom of the shell is a light brown. I think something is wrong with him his shell looks like their are two small tennis balls under it on both sides. (if you cut him in half this way - you would go right through them) outher then that he looks a little older but in good health. Thanks for any help.
