Yes, a clam. Yesterday I was fishing a lake at the hunting club for bass w/ a red worm, when I pulled up what I thought was a snag. Nope, it was a freshwater clam. The thing had clamped down on my worm! It couldn't have been trying to eat it, b/c they are siphon feeders, they just get food out of particles floating in the water. I figure it was just scooting along and accidentally clamped my worm. I split it open with my knife, and thought about using the insides for catfish bait, but I didn't have my cat rod on the four-wheeler, and I had fished for cats a couple of hours the day before and didn't even get the slightest hint of a bite. I caught one bass, and over two days we caught around twelve. I didn't fish the entire time though, pig hunted both mornings I was out there. I saw one pig, but it bounded off too quick for me to get a shot off, and we put a stalk on it, but it was long gone.
