Big Al is a alligator snapping turtle and a pretty fantastical apparition, but he’s more scientifically accurate than first impressions might suggest. For instance, he’s ten feet long from tip to tail. That’s how big these turtles can get. Not kidding. The largest ever caught weighed over three hundred pounds. The facial expression also reflects nature. These turtles lurk on the bottoms of rivers and sloughs with their mouths gaping wide. Fleshy processes on their tongues resemble worms. When an unsuspecting minnow comes after the lure, SNAP! Alligator snapping turtles are known to live at least 300 years.
