If you’re on a British beach, you might find ‘mermaid’s purses’. These are the empty eggcases of large fish including sharks and rays. An embryo fish has grown inside, hatched and left the eggcase to be washed away. Often it ends up washed onto a beach.
But even if you’re not a Customs offical, if you visit British beaches you can help to conserve sharks and rays. You might choose to report eggcase finds in the Shark Trust’s Great Eggcase Hunt. This is about discovering which kinds of shark and ray breed in our waters. If we know what’s there, scientists can advise on how to conserve these animals.
