Florida softshell turtle spotted at Dinner Island Ranch WMA near a canal. This female, about 18 inches long has webbed feet and spends its day basking in the sun or floating on the water. The soft shell turtle is the largest of Florida land turtles and are the oldest living group of reptiles dating back to dinosaur times. Turtles are the only toothless reptiles, although their horny beaks have sharp biting edges.
