Some beautiful fluorescence under 365nm UV light in these Gibbula cinereria (top; aka Grey Topshells), Trivia monacha (centre; aka European cowrie) and Trivia arctica (bottom; aka Arctic cowrie) found on a beach in Iona today . What are these creatures doing with fluorescence in their daily lives? πŸ€” #Seashells #Mollusca #Mull #Iona

Ps this phenomenon was first discovered by Alex Comfort ( #JoyOfSex ) in the 1940s...
