Researchers found dozens of mutated butterflies near the site of the nuclear accident in Fukushima, prompting officials to say it's the first sign of damage to the ecosystem.

According to NBC News, researcher Joji Otaki of the University of Ryukyus found mutation in roughly 12 percent of 144 commonly-found pale grass blue butterflies collected two months after the March 2011 disaster at the Fukushima nuclear plant.
