The upper right panel shows the measurements that are larger in the Southern Tidewater Goby (E. kristinae) in red and larger in the Northern Tidewater Goby (E. newberryi) in blue, with graphs of the five most distinguishing measurements. The range map on the right shows the geographic boundary between the historic ranges of the two species. Note the inferred range (blue dash), historically verified sampled range (yellow bar) and current populations (red dots) of the Southern Tidewater Goby. A photograph of the Southern Tidewater Goby appears in the Lower left.
