Princess Alice Bank (mobula dive)
Princess Alice Bank is the best-known dive in the central Azores: a deep-ocean seamount about 45 nautical miles (83 km) southwest of Pico/Faial, rising from over 1,500 m to about 32 m below the surface. In summer groups of 20–40 sicklefin devil rays (Mobula tarapacana, 'giant mobulas') gather here with barracuda and other pelagics; oceanic manta rays are also reported at the site. An expedition-level, exposed dive with current, usually done from a descent line.
depth: 32–60 m
