Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2007-05-22
Assessor/s: Findley, L.
Reviewer/s: Carpenter, K., Polidoro, B. & Livingstone, S. (Global Marine Species Assessment Team)
Justification:
This species is restricted to the southern half of California and the northern Gulf of California, and is considered common throughout its range. Coastal development within its range may pose a threat to this species. Although there is no current indication of widespread population decline, this species and its habitat should be carefully monitored. It is listed as Least Concern. However, if the northern most Gulf of California population is determined to be a separate valid species, it would likely be listed in a threatened category.
