During the course of the three-year study, park staff and contract
biologists from Zara Environmental in Austin, Texas, visited 30 caves
in the two parks as well as five caves in Yosemite National Park.
Zara Environmental specializes in work with cave animals.
Sequoia and Kings Canyon National Parks have 238 known caves. Most
people visit caves for the adventure of a subterranean world or to
see beautiful cave formations, but below their feet and over their
heads are surprising and varied animals that make caves their home.
Previous work in park caves had revealed a few other specialized
organisms including white and eyeless animals adapted to the
ever-dark cave environment.
