 to cave habitats in light of its unusual morphology and swimming 

 mode of locomotion.

FLORIDA CAVE AMPHIPOD 



Crangonyx grandimanus Bousfield, 1963. National Museum of 

 Canada, Natural History Paper No. 18:1-9. TYPE LOCALITY: Indian 

 Cave, 11.7 km (7 mi) southwest of Ocala, Marion County, Florida. 

 Holotype (NMC 5002), R. D. Warren (coll.), 18 February 1961. Paratype 

 (NMC 5003) from Huggin's Cave, Alachua County, R. D. Warren 

 (coll.), December 1961. 



DISTRIBUTION: WOODVILLE, OCALA (Upper Suwannee, Lower 

 Suwannee, Marion, Gulf Coastal Lowlands) and MIAMI FAUNAS. 

 This amphipod was listed as a Species of Special Concern by the 

 Florida Committee on Rare and Endangered Plants and Animals (Franz 

 1982) because of its subterranean habits and limited distribution, and 

 as a candidate for federal protection (Wood 1992). It appears to be 

 widespread in groundwater habitats associated with limestone areas 

 on the western slope of the old Northern Highlands in the Florida 

 peninsula. This amphipod is known from the Woodville Karst in the 

 St. Marks-Wakulla River basin, northern peninsula karsts from the 

 Suwannee River south to Pasco County and from the Miami karst; 

 however, it is rare at most sites. This amphipod has not been collected 

 on the eastern slope in the St. Johns River valley.
