Description
The Okaloosa darter (Etheostoma okaloosae) is indigenous to freshwater streams and tributary systems in Okaloosa and Walton Counties in northwest Florida.
The Okaloosa darter is a small slender fish with a maximum length of 5.3 cm (2.1 in) but a more common adult size is 4.3 cm (1.7 in).
It is a silvery brownish-green in color with irregular dark mottling and longitudinal lines of tiny dark spots.
The Okaloosa darter is restricted to six small river systems draining into the Choctawhatchee Bay drainage system in Okaloosa and Walton counties in the panhandle of Florida. Ninety percent of its range is within the Eglin Air Force Base. It is found in shallow clear creeks among vegetation over sandy bottoms. Eggs are deposited on the bed of the creek and are not guarded by an adult fish as happens in some members of this family.
