The geography is just right for seashells to wash up on Sanibel Island in Florida. Reporter Ari Daniel Shapiro profiles two seashell enthusiasts – an amateur collector and a scientist – who bonded over their mutual love of seashells.

Transcript

GELLERMAN: She sells seashells by the seashore, but on some special beaches the shells just pile up at your feet, for free! Sanibel Island on Florida's Gulf Coast has a beach like that. And reporter Ari Daniel Shapiro took a trip to the seashore, with his mom.

SHAPIRO: I’m going to tell you about two guys who love seashells. One of them’s an enthusiast, the other’s a scientist, and they’re tied together by the thrill of discovery.

OTHS: Let’s walk down this way and see if we can find something else.

SHAPIRO: Jeff Oths is the enthusiast. He made his big discovery in his own backyard, if the beaches of Sanibel Island count as a backyard. He’s lived on the west coast of Florida for eight years. Several days a week, he’s out here, working the shoreline, scanning the sand for shells.

OTHS: When you live here, the bottom of your feet become like leather, 'cause you’re barefoot all the time.

SHAPIRO: Oths is vice president of the local shell club, and he’s got a big collection at home.

OTHS: I stay in the guest room, 'cause the master bedroom was larger and I had more space for my shells.

SHAPIRO: And when the tide’s out here, the beaches are just coated with seashells.

OTHS: Beautiful – this is a little rice shell, and you probably wouldn’t see it right away.

SHPAIRO: Yeah, it looks like a rice grain. Why is Sanibel such a good place to find shells?

OTHS: Well, it’s all about the geography 'cause the island is sort of perpendicular to the current. It’s like a big catcher’s mitt so the shells come up and down the coast with the currents, and they wash up here on the beaches.

But, uh, let’s see what else we got here…

SHAPIRO: Oths bends down to pick up what looks like a clam. Except that it’s tiny, shiny, and pink. It’s a Rosepetal Tellin.

OTHS: These are adorable, aren’t they. They’re just beautiful. Look at that color.

MOM: Oh, that’s pretty.

SHAPIRO: That’s my mom. Oths was showing me and my parents around the beach.

MOM: Do you think that since you’re looking at all these shells that tend to be pretty much the same, that you seek out the ones that are so different?

OTHS: It’s almost like a texture that you look for and you’ll see this sort of a matrix of rubble. I did have some really good fortune earlier.

[SHAKING SHELLS]

SHAPIRO: He shows us two shells in his hand. They’re like mini soft-serve ice cream cones. Two tiny swirls of white shell. These Wentletraps, or Epitonium angulatum, look small to me, no bigger than a double A battery, but the other shellers on the beach, they’re impressed. Maybe even a little jealous.

WOMAN: Oh, wow! Where’d you get those? Those are gorgeous.

OTHS: Just on the driftline.

MAN: Those are huge! I’ve never found anything like that. Wow, good for you.

SHAPIRO: The amateur shellers of Sanibel are a beach-scanning army. Every day of the year, they fan across the island, looking for curious shapes and textures. And once in a while, one of them gets lucky. Like Jeff Oths, on Christmas day in 2009.

OTHS: You never know what you’re gonna find, or what to expect. So immediately I knew that it was something unusual.

SHAPIRO: In a pile of shells, he struck upon Australium phoebium, or the long spine star snail. And it turned out to be Sanibel’s 300th reported species of shell. But rather than adding it to his collection in his master bedroom, Oths gave it to another shell lover.

LEAL: I do have some of the favorites in this area.

SHAPIRO: José Leal is the scientist in this story. He’s the director and curator of Sanibel’s shell museum.

Jeff Oths’s shell now resides amongst well over 100,000 other shells, from across the world. Leal says he’s skeptical when a new shell’s found on Sanibel.

LEAL: We have to be very careful before we fully assume that it’s actually living out there.

SHAPIRO: So did you have any doubts when Jeff turned up this 300th species?

LEAL: Well, yes, and then I proceeded to ask him questions. Where did you find it? Well, I found it in the water. That’s a good sign. Another hint is that that shell is not a very collectible shell. It is a nice shell, but it is not something you can buy elsewhere.

SHAPIRO: The museum does house a number of specimens valuable to the shell trade.

[SOUND OF CABINET BEING UNLOCKED AND OPENED]

SHAPIRO: That’s why the cabinets are locked up tight. Shells also get secured if they’re important to science. Leal opens a cabinet and pulls out one such shell that came from the Florida Keys. The two halves fit together like a little orange heart. Leal named this specimen.

LEAL: I created a new genus name, which is a higher category, including a few species. When I first saw the shell, it didn’t strike me as anything that anybody knew at that time. The combination of being a predator and living its entire life glued to a rock was unheard of in mollusks.

SHAPIRO: Leal had to unravel these puzzling features of the shell’s life, which is how he came up with the genus name.

LEAL: I created the name Dilemma.

SHAPIRO: This one’s Dilemma frumarkernorum. Leal loves shells, and seeing one for the first time, he says there’s nothing like it. It’s what got him hooked as a boy growing up on the beaches of Rio.

LEAL: I still have these recollections of the water, the glimmering, the sunlight going through. And all of a sudden, you find a little clam, that special shell. I think if you collect your own shells, and you’re walking, you know, and you found five different kinds, there is always a chance that you’ll find a sixth one, a seventh one. And eventually the tenth one will be something wonderful, and beyond, you know, your imagination.

SHAPIRO: It’s this feeling that keeps both Jeff Oths and José Leal combing the Sanibel beaches. Wondering whether their next step will bring them face to face with something they’ve never seen before. A little sandy promise.

LEAL: So I think that’s the main attraction is being consumed by the unknown. You know, the surprise element in shelling.

SHAPIRO: You just have to keep your eyes open.
