Fig. 5.11 Bank reefs can also have spawning aggregations and their hydrodynamic environment
is very different from that of shallow reefs and islands. ( a ) Saba Bank, a sunken atoll, has a red
hind aggregation within the box indicated, as well as a variety of promontories and other features
visible in this satellite image. ( b ) “Riley’s Hump” ( white box ) at the SW corner of the Dry Tortugas
