You wouldn’t be smiling either. Titan Beetles can grow to 6-1/2 inches. And then, there’s their teeth… or pinchers… or front legs… or something. Strong enough to break a human finger. (“Here, Honey: hold this nice bug and we’ll have a fun picture for show-n-tell when you get back from the ER.”)
To see a Titan Beetle, go to a South American rain forest. Just keep your hands inside the car.
