Tiny Grand Canyon Pseudoscorpion Among Candidate Species Listing Under Endangered Species Act
A tiny scorpion-like invertebrate found only in Grand Canyon National Park is among 67 plant, animal and insect species that the U.S. Fish and Wildlife Service says might be eligible for listing as a threatened or endangered species under the Endangered Species Act.
The "Grand Canyon Cave Scorpion" is thought to exist only in the "Cave of the Domes" in the national park. Located on Horseshoe Mesa, the cave is one of an estimated 1,000 caves in the park but is the only one legally open to visitors.
The Fish and Wildlife Service is initiating a more thorough status review of the 67 species to determine if listing is warranted. The 67 species occur in 16 states and Mexico.
