Photoluminescence in Puerto Rican Land Snails

This study investigates the photoluminescence response of various gastropod species under ultraviolet (UV) light, focusing on their flesh, mucus, and shells. Biofluorescence was observed in 18 out of 33 species tested, with responses ranging from subtle to intense, primarily under long-wave UV radiation (365 nm). No bioluminescence was detected. Species such as Gaeotis nigrolineata, Veronicella cubensis, and Cerion striatellum exhibited vivid fluorescence, including green, turquoise, blue-green,
