ANNUAL REPORT 2025 2025 was another fabulous year for all things eggcase..... Over the last year our citizen scientists have been very busy, recording a whopping 55,727 eggcases! Even better, we only had SIX days from the whole year where an eggcase wasn’t reported. That’s incredible work - a massive THANK YOU to everyone who submitted an eggcase record in 2025! By recording shark and skate eggcases that wash up on the beach, or those seen developing underwater, we can get a better understanding of the presence and diversity of egglaying species in British waters and beyond!
