The banks are also used by groupers and snappers that support a major fishery.
The banks lie within the Florida Keys National Marine Sanctuary.
Tortugas Bank is the westernmost feature of the Florida Keys, but it is a submarine feature, wholly submerged, without any islands or above-water rocks.
A depth of less than 18 meters is found in a circle of 4 km diameter around the center of the bank.
Tortugas Bank is about 14 km west of Loggerhead Key, the westernmost islet of the Dry Tortugas and the closest piece of land.
