Octopus

Common octopus are exceptionally abundant in the granite boulder terrain around Capo Testa, which provides ideal denning habitat across the full depth range of the site. They are tactile problem-solvers capable of opening shellfish, using tools, and navigating complex environments — capacities that make them endlessly engaging dive companions. Day dives regularly reveal 5 to 10 individuals active in and around their dens, which are identifiable by the shell middens they accumulate outside the entrance.
