Seashells: They're beautiful remnants to carry home from the beach—and so much more! According to environmental journalist [https://www.cynthiabarnett.net/"target="\_blank"]( Cynthia Barnett, seashells record history more accurately than the humans who first wrote it down. In this episode, we talk about the science of seashells, their impact on humankind and the scientist behind a very famous tongue twister. **Check out Cynthia’s book** [https://www.cynthiabarnett.net/shop/p/the-sound-of-the-sea-hardcover"target="\_blank"]( **The Sound of the Sea** **and check out Emily’s** [https://lnk.to/YmA2sk"target="\_blank"]( **reporting on sandcastles** **.** _Interested in more marine biology stories?
