Exchange Of The Day

R: "Where are a clam's eyes and nose?

Me: "They don't have any." [Editor's Note: Uh, that's right, isn't it?]

R: "Then how do they know where they're going?"

Me: "They don't." [Editor's Note: Ibid.]

R: "Well then no wonder they get ate."

Well... clams do generally have an eye spot, which they can use to sense light intensity. Since they eat plankton (which is most often plant-life) they usually need to be in a reasonably well-lit area. So they use the eye spot to make sure they're in a hospitable place.

When confirming this, I also found that some scientists think that mollusks have some analog to a sense of smell, where they can detect chemical signatures in the water.

They also have a "foot" which is the fibrous stuff they use to attach to the sea floor. And many species can move by squeezing their shells together.

Here is a site from Woods Hole with a "shellfish FAQ" that Ryan might find interesting.

And then again, who needs a scientific explanation, when there is a kid with a really cool answer. ;)
