Answers to common questions

Q. We hear a lot about the threat of zebra mussels to native freshwater mussels. Is a mussel the same as a clam?

A. Not quite, says Dan Kelner, a malacologist (clam expert) with the DNR Ecological Resources Division. Both freshwater mussels and clams are in the mollusk group of animals, which also includes snails and slugs, but they have important differences:

1. Mussels can make pearls, but clams cannot.
2. Freshwater mussels have parasitic young, but clams don’t.
3. Minnesota only has a few species of tiny clams but more than two dozen species of mussels.
