Threats [top]

Major Threat(s): There are no known major threats to the Belted Blenny. However, given its shallow reef habitat and restricted range it may be negatively impacted by localized stochastic events, such as oceanographic environmental changes from current or future ENSO events and climate change (Soto 2001, Chen et al. 2004).

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for the Belted Blenny. However, this species is present in the Galapagos Marine Reserve, the Galapagos Archipelago Particularly Sensitive Sea Area, the Galapagos Island World Heritage Site, and the Galapagos Island Man and Biosphere Reserve (WDPA 2006).
