In the Sierra Nevada Mountains of California, researchers have discovered about 30 species of eye-opening cave creatures.
One of the scientists making these discoveries received her doctorate from the University of Texas.
Biologist Jean Krejca entered her first cave 20 years ago.
The idea that you could go where no one has gone before, that kind of exploration, that sort of, you know, frontierism, really doesn't exist in that many places that are easily accessible on the surface," Krejca said.
