Amblyrhynchus cristatus is endemic to the Galápagos Islands,
Ecuador. A. c. mertensi is found on San Cristobal and Santiago
Islands. Extent of occurrence is estimated at less than 100 km²
and area of occupancy at less than 10 km². San Cristobal Island
was the site of a shipwreck in January 2001, which spilled
diesel oil/bunker fuel along the southwest coast of the island.
Although A. c. mertensi is found on two different islands, the
population is low on Santiago and unknown (but probably low) on
San Cristobal. The 2001 oil spill is likely to have caused high
(around 60%) mortality to the San Cristobal population, based on
the location of the spill and its effects on other nearby
islands (Santa Fe). feral dogs an
