Assessment Information [top]

Red List Category & Criteria:	Vulnerable D2 ver 3.1
Year Published:	2010
Assessor/s:	Hastings, P. & Dominici-Arosemena, A.
Reviewer/s:	Carpenter, K., Polidoro, B. & Livingstone, S. (Global Marine Species Assessment Team)
Contributor/s:
Justification: This species is only known from two locations (Galápagos and Malpelo Islands). Regional experts support the plausible threat of the increased duration and frequency of ENSO events that can cause severe and rapid declines for restricted-range, shallow-water species in this region of the Eastern Tropical Pacific. This species is listed as Vulnerable under Criterion D2.

Geographic Range [top]

Range Description:	This species is endemic to the Eastern Pacific, and is found only in the Galápagos and Malpelo Islands.
Countries:	Native: Colombia; Ecuador
FAO Marine Fishing Areas:	Native: Pacific – southeast

Population [top]

Population:	This species is considered common, and is the most abundant member of its genus in the Galápagos. The overall mean abundance for the species in Galapagos island was 2.55 (per 500 m²) (Edgar et al. 2004).
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	This reef-associated species occurs in a wide range of habitats to depths of 25 m, from boulder strewn slopes and rocky reefs to ledges and undercuts along wall faces (Humann and Deloach 1993).
Systems:	Marine

Threats [top]

Major Threat(s):	In the Eastern Tropical Pacific, severe localized fish species declines have occurred after strong ENSO events that result in shallow waters that are too warm and nutrient poor for extended periods of time (Grove 1985, Edgar et al. 2009). The frequency and duration of ENSO events in this region of the Eastern Tropical Pacific (e.g. the up-welling zone off the coast of Peru, Ecuador, Colombia, Panama and the offshore islands) appears to be increasing (Glynn and Ault 2000, Soto 2001, Chen et al. 2004). Given this species’ restricted distribution and shallow water habitat, oceanographic environmental changes, such as those associated with future ENSO events, may have detrimental effects on the survival of this species.
