Salt Creek pupfish are found exclusively in the Salt Creek drainage of Death Valley and have adapted to survive extreme changes in environment, living in water that ranges in temperature from near freezing to 40°C and may have salinities as high as 35 ppt. They are thought to be the remainders of a large ecosystem of fish species that once lived in Lake Manly, which dried up at the end of the last ice age leaving behind the present day Death Valley. The desert pupfish has been classified as endangered by the IUCN due to its extremely restricted distribution.
