It’s one of our biggest events of the year, and this time International Horseshoe Crab Day will be even more special on Friday, June 19 between 10am and 2pm.

2026 marks the tenth year of our Horseshoe Crab Aquaculture Program, which has been educating people about these incredible ‘living fossils’. It’s also our fifth year celebrating International Horseshoe Crab Day itself.

We will also have special guest speaker Liana DiNunzio, shorebird biologist from Manomet Conservation Sciences, who will be talking about her work monitoring horseshoe crabs at the Monomoy National Wildlife Refuge Center.

Come to the Museum and join the party, including:

• See live horseshoe crabs at every life stage with opportunities to watch feedings
• Take part in interactive exhibits
• Learn about their fascinating life histories and their human impact
• Enjoy Arts & crafts and a Museum scavenger hunt

All Horseshoe Crab Day events are included with Museum admission.

Guest Speaker Liana DiNunzio will appear at 2:30pm. Tickets also included with admission or separately for $8.

What an amazing week of horseshoe crabs! Thank you to everyone who has shared sightings from across the state as part of the Horseshoe Crab Challenge! We’ve received reports from the South Coast, Cape Cod, and South Shore, and we’re excited for more observations to come in!

And a special shout out to Stage Harbor in Chatham, where we recorded a new milestone on the spawning beach survey—125 horseshoe crabs found in a single 5 x 5-meter survey quadrat, the highest count we’ve documented!

What incredible weather to start the first day of our 3-day Meet the River event with Dennis-Yarmouth Intermediate School. In this photo Kitty Hendricks from the Mashpee Wampanoag Tribe highlights some of the tools and toys made and used for centuries by the People of the Firet Light.

Today’s forecast calls for fewer sunburns but just as much fun!

So excited to host our annual Meet the River Event for DY 7th graders this week at west Dennis beach. Horseshoe crabs play a big role in the learning experience!

Have you checked the tide charts? 🌊 This weekend could be a great time to spot horseshoe crabs!

With the new moon on Saturday and high tides happening coastwide from the morning into the early afternoon, conditions may be just right for sightings. If you find any, don’t forget to submit your observations to the Horseshoe Crab Challenge—we’ll be featuring photos of sightings here next week!
