There is little known about this species' population, habitat status, or vulnerability to threats. More information is needed on the extent of coastal development within its range, as well as on the potential effect of localized stochastic events such as ENSO or climate change on this restricted range and shallow-water species. It is listed as Data Deficient.

Habitat and Ecology [top]

Habitat and Ecology:This reef-associated species inhabits rocky reefs covered with algae in shallow waters, including tide pools. It can also be found in barnacles and worm tubes.

Threats [top]

Major Threat(s): This shallow-water species has a restricted distribution and very narrow depth range. Localized stochastic events including future oceanographic environmental changes from ENSO and global warming events as well as coastal development may have detrimental effects on the survival of these shallow water regional endemic species (Soto 2001, Chen et al. 2004).

Conservation Actions [top]

Conservation Actions: There are no known conservation measures for this species. However, this species' distribution falls into a number of Marine Protected Areas in the Eastern Pacific region (WDPA 2006). However, more information is needed to assess the extent of coastal development within its range, as well as its population and habitat status.
