FIGURE 1 in Taxonomy of the Speckled Dace Species Complex (Cypriniformes: Leuciscidae, Rhinichthys) in California, USA

FIGURE 1. Top: Lahontan Speckled Dace (ca. 70 mm TL) and cover habitat in Taylor Creek, California, a tributary to Lake Tahoe. The body shape, stripe on head, and speckling are characteristic of live fish in many populations from Mexico to Canada that have been considered to be just one species, Speckled Dace (Rhinichthys osculus).
