Science in Action: Snails in Cages

Cabrillo National Monument


Select species of seaweeds generate noxious chemicals to defend themselves against would be predators. One such species, the rockweed (Silvetia compressa), can be found atop rocky outcrops throughout Cabrillo National Monument’s intertidal zone. In partnership with the United States Navy and Cabrillo biologists, Dr. Jeremy Long from San Diego State University investigates the intricate interactions between this brown seaweed and the prevalent black turban snail, Tegula funebralis. Dr. Long’s research will provide a better understanding of these chemically driven interactions and how they influence the larger ecosystem.
