Population
This species is relatively common throughout its range in the Gulf of California. However, according to
Aburto-Oropeza and Balart (2001), this fish is rare in Los Islotes, Gulf of California, with an occurrence
frequency below 10%, and this species is considered scarce Cabo Pulmo, Gulf of California (VillarrealCavazos et al. 2000).
This fish was studied in various sites at Galapagos archipelago with an overall mean density of 0.09
ind./500 m2 (Edgar et al. 2004).
Current Population Trend: Unknown
Habitat and Ecology (see Appendix for additional information)
This reef-associated species lives in sand-rubble fringe of rocky reefs or coral patches at depths of 2 to
40m (Allen and Robertson, 1994). According to Dominici-Arosemena and Wolff (2006), this species is
present in edge habitats on sandy deep rocky zones in the Gulf of Chiriqui, Panama and is one of the
most dominant species of gobiids. It forages on tiny crustaceans among rocks on the bottom.
Systems: Marine
Threats
There are no major threats known for this species.
Conservation Actions (see Appendix for additional information)
There are no known conservation measures for this species. However, this species distribution falls
partially into a number of Marine Protected Areas in the Eastern Pacific region (WDPA 2006).
