About

The Seashell Museum is now located at CEDO Intercultural near the iconic whale bone in Las Conchas. This beautifully curated private collection showcases seashells gathered and preserved by longtime Rocky Point resident Naomi Black.

History & Accomplishments

In the summer of 2017, Russ and Naomi Black created the museum next to Naomi’s shop, Sea Debris, which opened in January 2018. In 2025, Naomi partnered with the Intercultural Center for Desert and Ocean Studies (CEDO Intercultural) to relocate the museum to Las Conchas.

Since opening, it has been voted the #1 museum in the State of Sonora by TripAdvisor and has welcomed over 3,500 visitors from countries including Australia, Belarus, Canada, Chile, Germany, the Philippines, Mexico (10 states), and the United States (25 states). The museum is family-friendly and offers free admission to all visitors.

While exploring the Seashell Museum at CEDO, be sure to visit the gift shop for Naomi’s 32-page coloring book, “A Special Seashell Sunday.” Illustrated by Tina Green, this educational and engaging book is perfect for kids and costs $15 USD (with free shipping in the US).

What's at the Seashell Museum?

The collection features seashells native to the Sea of Cortez and collected around the Puerto Peñasco area. Each shell is carefully labeled with its name, size, and origin.

You can also purchase a 24” x 36” Seashell Identifier Poster created by Naomi in collaboration with In Focus Photography (Manny Sanchez). Packed with information on local shells, it’s available at the museum or online for $25 USD — a wonderful keepsake to help you identify shells during beach walks.

Hours of Operation

The Seashell Museum at CEDO is open to the public Monday through Saturday, following CEDO’s business hours (approximately 10 a.m. to 3 p.m.). While you're there, ask about CEDO Xperiences for guided outdoor adventures exploring the desert and sea.
