Marine Life

The marine life on the Lisbon Coast is varied due to the convergence of river outflows and the Atlantic. Divers can expect to see schools of fish such as sea bream, bass, and the occasional octopus. Invertebrate species, including anemones, sponges, and nudibranchs, add color and texture to the underwater landscape.
