How Do Mussels Get Their Shells?

We're heading to the coast of Maine to learn a little bit about why the sea is salty and how mussels get their shells with Zach Whitener, a research associate at the Gulf of Maine Research Institute in Portland, Maine. We also get an answer to a question to how you get a ship in a bottle from Colorado-based ship-in-bottle builder Daniel Siemens in this encore episode from 2016.
