Size: 89 mm.
Native Range: Marine; G. seta is found only in the northern Gulf of California in the rocky intertidal zone (Barlow 1961; Thomson et al. 1979).

† Populations may not be currently present.
Means of Introduction: Intentionally stocked as forage. Sixty-three fish were stocked. Stock was obtained from San Felipe, Mexico (Walker et al. 1961).
Status: The introduction failed to produce a viable population and is no longer extant in the Salton Sea.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
