|Population:||This species is considered common throughout much of its range. |
A survey made in Gulf Dulce, Costa Rica, showed a mean density of 0.004 ind/ m2 for this species (Figueroa, 2001). This species was considered to be rare in Los Islotes, Gulf of California, with an occurrence frequency between 10 and 15% (Aburto-Oropeza and Balart, 2001), and was not found in surveys at Gulf of Papagayo, Costa Rica (Dominici-Arosemena et al. 2005), nor at Gorgona Island coral reefs, Colombia (Zapata and Morales, 1997). In Bahía de Navidad, Jalisco, México, this fish was captured 10 times within 12 (one each month) field trips throughout a year (Rojo-Vázquez et al. 2001).
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This reef-associated species is often solitary, and can be found hiding in reefs and caves during the day (McKay and Schneider 1995) to depths of 30m. This species was also found with a frequency of 9% in estuaries associated with mangroves in Gulf of Nicoya, Costa Rica (Rojas et al. 1994). It is feeds on reef invertebrates at night (McKay and Schneider 1995), and forms resting schools on reefs during the day.|
|Major Threat(s):||There are no major threats known for this species. In some areas, such as in the Galapagos, this species is caught in artesanal fisheries. Populations of haemulid species (Orthopristis spp., Anisotremus interruptus and A. scapularis, Haemulon scudderi) declined more than 50% during 1997/98 El Nino, but populations have recoved over a subsequent two year period.|
|Conservation Actions:||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).|
