|Scientific Name:||Elassoma okatie|
|Species Authority:||Rohde & Arndt, 1987|
|Red List Category & Criteria:||Vulnerable D2 ver 3.1|
|Reviewer(s):||Smith, K. & Darwall, W.R.T.|
|Facilitator/Compiler(s):||Hammerson, G.A. & Ormes, M.|
This species is listed as Vulnerable because its known area of occupancy appears to be less than 20 sq km, the number of locations might not be greater than five, and the species occurs only in sites that are highly vulnerable to degradation or destruction..
|Range Description:||This species is known from three areas in the Edisto, New, and Savannah river drainages, southern South Carolina and adjacent Georgia; most specimens have been taken from roadside drainage ditches in Jasper County, South Carolina, in the New and Savannah river drainages (Rohde and Arndt 1987).|

This species is represented by at least several distinct occurrences (subpopulations).
Trend over the past three generations is unknown but probably relatively stable or slowly declining.
|Habitat and Ecology:||Habitat includes shallow, quiet water (drainage ditches, pondlike ditches, backwaters of creeks and rivers), with a soft detritus-rich substrate and abundant emergent and/or submerged aquatic vegetation; often in human-disturbed habitats (Rohde and Arndt 1987, see this for further details).|
|Use and Trade:||This species is not utilized.|
|Major Threat(s):||All known sites are heavily impacted by humans (e.g., sites between highways, near boat ramp where forest was cleared) (Rohde and Arndt 1987). No known populations are threatened, but their occurrence mostly along roadsides makes them vulnerable to habitat alteration and/or pollution (Rohde and Arndt 1987).|
This species would benefit from habitat restoration, improved habitat protection and management, and better information on distribution, abundance, population trend, and threats.
