Food Preference of Snapping Turtles
You're driving down the road on a perfectly nice Spring day and you spot a turtle. Being the good Samaritan that you are, you decide to get out and help it. First, you have to identify it, then figure out if it's going to bite you, and if it's safe to move. I've found myself in this position countless times, usually in sandals and standing a few feet from said turtle wondering if it was going to try to bite. How can you tell if the turtle you're facing is a snapper? Check out these photos:

This is a juvenile snapping turtle, about the size of a silver dollar:
Regardless of whether you encounter a harmless box turtle or bitey snapping turtle in the road, try to help it get to the side of the road that it's traveling (if it is safe for you). My general feeling is that you shouldn't actually try to handle a snapping turtle but here are a few ideas (note, they don't suggest poking with sticks, this can injure the turtle or he can snap it in half and then it's useless):
Contrary to the idea that snapping turtles eat fingers (which they will snap at if you get too close), their diet is wide and varied. They are omnivores, but the majority of their diet is aquatic vegetation (about 65%). This seems contrary to the large set of jaws and defenses they have, but like their dinosaur ancestors they're mostly herbivores. The other major part of their diet is fish. Because they are slow and ungainly swimmers they usually eat slower moving fish and non-game fish species (which also makes them less of a nuisance to fishermen), water snakes, or eels. Occasionally they will eat dead stuff (fish, frogs, animals), amphibians, invertebrates like crayfish, worms, or beetles. They may even eat the occasional small mammal thrown in for variety, after all, balanced diet is a very good thing!
Let's face it, snapping turtles (and especially the huge ones) are like the land barges of the fresh water turtle world. They're slow and not very hydro-dynamic. They would rather eat sessile (not moving) plants than chase down anything. In fact most of their hunting technique consists of sitting in the mud and waiting for something to toodle or swim by. They can sometimes stalk prey by moving slowly and then snapping them up.
Here where I live they also like to eat waterfowl ducklings. I can't tell you how many times I've seen mother geese or Mamma mallards swimming with 10-12 young, and then the next day the number is cut in 1/2. I've even seen ducklings pulled underwater without so much as a ripple of water, just the flash of a turtle shell. From the research I've read, water fowl is only a small part of their diet, and they don't have a major impact on their populations (this is why Mamma ducks and geese have so many young!).
To answer the question, what do snapping turtles eat? Well, the answer is almost anything that is easy to get, and at that, mostly plants. They aren't a threat to sports fishermen or major fisheries, but they are an important part of wetland food webs. This is why you should always help them across the road (carefully), and let them go on their way.
