Northern Puffer

Newport lies where Narragansett Bay meets Rhode Island Sound, creating a cold-water diving environment shaped by tides, Atlantic swells, and a rugged seabed of granite ledges, boulders, sand, and seasonal algae. Rocky habitats support tautog, cunner, black sea bass, northern puffers, skates, sea stars, crabs, and American lobsters, while anemones, sponges, and tunicates cover sheltered surfaces. Diving conditions vary considerably with weather, currents, plankton, and tidal movement, making local knowledge important. Newport’s underwater landscape also reflects its long maritime history: the harbor and surrounding passages have supported Indigenous communities, fisheries, naval defenses, commercial shipping, and recreational sailing for centuries.

Notable Detail: British forces deliberately scuttled 13 transport vessels in Newport Harbor in 1778, creating a barrier intended to restrict French warships from entering the inner harbor.
