A blackish oblong shape moved slowly across the road toward my front lawn the other day. I had no idea what it was until it got much closer.
Snapping Turtles are fearsome predators, with powerful jaw muscles that can close the mouth with such force and velocity they can bite a small pineapple in half, or amputate human fingers. Needless to say, I left this one alone. They are at or near the top of the aquatic food chain as adults, but take 15-20 years to mature to reproductive age. Few snapping turtle hatchlings survive to adulthood, but adults are very long-lived.
