Habitat and Ecology [top]

Habitat and Ecology:P. galapagensis has been reported to occur from the low tide level (Taylor 1945) to at least 12 m depth (K.A. Miller and L. Garske pers. comms.).

Threats [top]

Major Threat(s): Presumably El Niño and climate change. Ecosystem interactions involving these two factors appear to have caused widespread decline in algal populations because of an increase in density of grazing sea urchins and other herbivores, following overexploitation of predators along with ENSO disturbances.

Conservation Actions [top]

Conservation Actions: P. galapagensis occurs within the Galápagos Marine Reserve (IUCN category VI); Galápagos Archipelago Particularly Sensitive Sea Area (PSSA); Galápagos Island World Heritage Site (UNESCO N (i)(ii)(iii)(iv)), and Galápagos Island Man and Biosphere Reserve (UNESCO).
