Help Solve a Beach Mystery

We get lots of inquiries from beachcombers trying to identify their beach finds. Sometimes we can help find out what someone found on the beach, but sometimes even experienced beachcombers can't help us figure it out. So, we're hoping this page helps harness the collective knowledge of our worldwide beachcombing community to solve these mysteries from the beach.

Animal or Plant? SOLVED

Does anyone recognize these round things Ralph found on the beach near Darwin Australia in January 2023? The left photo shows when they are wet, the right after a day drying. When they were wet, they were about .75 inches (2 cm); dry they were about .5 inches (1.5 cm). SOLVED: “I have been looking at books and they could be related to bluebottles — they could be Velella or Porpita, that have lost their color and tentacles.”

More help identifying your finds

• If you are lucky enough to discover something on your own beach that you suspect might be of historical or scientific significance, please contact a local history or natural history museum or organization to find out more about your find. Local organizations have knowledge about who and what has lived in your area in the recent, ancient, and prehistoric past and are best suited to pinpoint the origin of your find.
• Check the Resources page for a list of online information sources for identifying glass, shells, fossils, and more.
• Bring your find to a beachcombing event and see if anyone there knows what you have found. Many sea glass and seashell festivals are filled with collectors who have extensive knowledge and love being asked to help you identify your special finds.
• Sometimes it's not clear if you have found something made of stone, glass, or something else. If you can't identify the material that your item is made from, contact a jeweler who does appraisals and might be able to determine if your find is glass, stone, or maybe even a precious gem.
• If you have found something special, consider making a gift of anything particularly interesting to an organization that accepts donations. It’s a great way to have your find appreciated by a broader audience, contribute to research…and clear out space for more beachcombing treasures.
