Details? Look back to the beginning.
While not as rare in captivity as they used to be, the Children’s Museum at Fair Park is still the place to see the world’s largest freshwater turtle in optimum conditions. The alligator snapping turtle, Macrochelys temminckii, ranges through Texas into the Gulf Coast, and occasionally as far north as Dallas. In 1987, I was lucky enough to see a large female in Carrollton, north of Dallas proper, during a very rare land excursion while she was hunting for a nesting site. The Children’s Aquarium alligator snapping turtle is about as big as the one I saw back then, with the help of a rich diet and a lot of care.
