Distribution. Cosmopolitan (Vinogradov et al. 1996). In the eastern Pacific from off the Columbia River, off western Baja California, and in the Gulf of California, Mexico (Siegel-Causey 1982, García Madrigal 2007).
Remarks. Siegel-Causey (1982) reported this species as a common inhabitant in the northern, central and southern Gulf of California. From 0 to 200 m depth (Vinogradov et al. 1996, García Madrigal 2007). Gasca et al. (2012) found it among the most abundant species in the Mexican tropical Pacific area linked to the California Current conditions.
