Male Wood Duck & Razorback Musk Turtle (while wood ducks are small, that's still one large musk turtle, as North American musks go). The ledge edging the land area looks to me like it's molded out of cement, concrete or mortar, but I'm not knowledgeable in such things. In hobbyist encloures, if you use concrete I recommend that after curing you apply a coat of an appropriate epoxy to reduce abrasiveness. Photo: Richard Lunsford.
