[1] The plain is home to five of the 27 reported species of troglobites in Florida and South Georgia including Woodville Karst cave crayfish and Swimming Florida cave isopod.
[2] Wakulla cave consists of a dendritic network of conduits of which 12 miles (19 km) have been surveyed and mapped.
The conduits are characterized as long tubes with diameter and depth being consistent (300 ft or 91 m depth); however, joining tubes can be divided by larger chambers of varying geometries.
The largest conduit trends south from the spring/cave entrance for over 3.8 miles (6.1 km).
[3] This connection established it as the longest underwater cave in the United States and the sixth largest in the world at a total of 32 miles (51 km) of surveyed passages.
