Hm, not really. We have bunches of books on reptiles but my obsessed son doesn’t really care whether they’re living books or not, lol. There is a good OOP series called “Biography of a _________” There are several, we have King Snake, I think there is an Alligator one, and a turtle one. They are for fairly young kids. Herbert Zim did a few books on reptiles, some of those are now OOP. We have his Snakes one. The All About series has some on snakes and I think turtles. One of the better authors today writing about snakes is Chris Mattison, we have many of his including Snake and Snakes of the World. We also have “living matter” in that we have three snakes, a gecko and a box turtle. Many libraries will have quite a section on reptiles, they may not all be “living” but in our experience most people who write about snakes really like them. 🙂 Reptiles make terrific pets!
