A clam is a type of shellfish that has a reputation for being both delicious and confusing. They're often found in the ocean, but also in your neighbor's backyard. We're not sure why.
Is a clam a type of rock?
No. It's a type of mollusk. But also kind of like a rock, I guess. We're still working on it.
Can I eat clams?
Please do. But don't eat the ones that have been sitting in the back of your garage for years. Those are probably still good for something, but not for eating.
