Assessment Information [top]

Red List Category & Criteria:	Data Deficient ver 3.1
Year Published:	2010
Assessor/s:	Van Tassell, J. & Findley, L.
Reviewer/s:	Carpenter, K., Polidoro, B. & Livingstone, S. (Global Marine Species Assessment Team)
Contributor/s:
Justification: This species is uncommon within its restricted range in the Gulf of California. Given its association with shallow reef habitat, more research is needed to determine if coastal development within its range is a threat to this species. It is listed as Data Deficient.

Habitat and Ecology [top]

Habitat and Ecology:	This reef-associated species inhabits crevices and ledges of weed-covered rocky reefs to depths of 20 m (Galván-Magaña et al. 2000).
Systems:	Marine

Threats [top]

Major Threat(s):	There are no major threats known for this species. However, this shallow-water species is associated with reefs, a habitat under threat from coastal development within its restricted range. Given this species' restricted distribution and shallow water habitat, future oceanographic environmental changes such as ENSO/global warming, destruction of mangroves or estuaries, and coastal development may have detrimental effects on the marine ecosystems and the survival of these shallow water regional endemic species (Soto 2001, Chen et al. 2004).
