Another native species has disappeared from Hawaii. The blue-tailed skink, last sited on the NaPali coast of Kauai, has been deemed extinct by the National Geological Survey. 

The copper striped blue-tailed skink (Emoia impar) — a sleek lizard with smooth, polished scales and a long, sky-blue tail — was last confirmed in the Na’Pali coast of Kauai in the 1960s. But repeated field surveys on Kauai, Oahu, Maui and Hawai’i islands from 1988 to 2008 have yielded no sightings or specimens. 

“No other landscape in these United States has been more impacted by extinction events and species invasions in historic times than the Hawaiian Islands, with as yet unknown long-term cascading consequences to the ecosystem,” said U.S. Geological Survey director Marcia McNutt. “Today, we close the book on one more animal that is unlikely to ever be re-established in this fragile island home.”

Scientists think that the lizard could be the victim of an invasive ant that was preying on it.
