I'm no turtle expert, but I believe it is only the rare (and protected) Alligator Snapping Turtle that lures it's prey with it's worm-like tongue.
Common Snapping Turtles, at my pond, are kinda like moles and mud daubers, around my place...the sooner I make "friends" with them the sooner I can sleep at night.
At certain times of the year, I can sit for a while and see them surface. At first I would pop them, but that left them (only a few) in the pond to later float back up and create that smell that lasted for days. I no longer worry about them as it seems to be common opinion that they are not like otters, water turkeys, and the GBH's and lay waste to our fish populations. I consider them much like vultures...nature's clean-up crew. I suppose if there were alot of them congregating on the pond that I would worry about what's bringing them in (like a fish kill) or worry that my feed bill was being wasted on them, but a couple snappers here and there just add some diversity to my pond.
