First Record of the Colonia Cnidarian Cordylophora lacustris Within a Flooded Cave System
W.J. Streever

Abstract

Fourteen colonies of the freshwater colonial cnidarian Cordylophora lacustris were found in the fully-flooded cave system at Little River Spring, Suwannee County, Florida. This is the first record of colonial cnidarians from caves. A plankton sample collected from the cave contained epigean species. Flow-reversal is suggested as a mechanism by which epigean fauna enters fully-flooded caves.
