I was glad Lucy was on a leash when we came upon this critter. She lunged toward it and who knows what would have happened. Looks like something that could get a hold of her nose and not let go no matter how much sweet talking you did. I don't believe pretty please would do it.
Only the second snapping turtle we've found on our place as it's a good 1/4 mile to the creek. But females will travel a fair distance from water to find sandy soil to lay their eggs. This looks like a big turtle to me but they can get as big as 20 inches long.
And it seems best to just leave them alone. From Wikipedia:"Lifting the turtle with the hands is difficult and dangerous. Snappers can stretch their necks back across their own carapace and to their hind feet on either side to bite. Also, their claws are sharp and capable of inflicting significant lacerations."
