Mutant butterflies caused by Fukushima disaster

An undated handout photograph released by Joji Otaki, an associate professor of biology at the University of the Ryukyus on 14 August 2012, shows a healthy adult pale grass blue (Zizeeria maha) butterfly (top) and a mutated variety (bottom). Severe mutations were found in butterflies collected near the Fukushima Daiichi nuclear power plant according to Japanese news reports on 13 August 2012. Exposure to radioactive material from the nuclear accident has caused the mutations, according to the team of scientists conducting the survey published in the journal Scientific Reports
Mutant ... butterflies have been found with smaller wings or damaged eyes

MUTANT butterflies have been discovered near the ruined Fukushima nuclear plant in Japan.

A crisis was unleashed when the devastating earthquake measuring 9.0 on the Richter scale struck.

The disaster, which killed 19,000, sent huge waves 20 metres high and wiped out cooling systems at the power plant.

And experts fear radiation levels could spark a string of genetic mutations after changes were found in butterflies.

Many pale grass blue butterflies born since the disaster have suffered abnormalities, including smaller wings and damaged eyes.

Scientists fear the fallout from the catastrophe could also harm other animals and people.

Radiation expert Kunikazu Noguchi said: "This is just one study, we need more studies to verify the entire picture of the impact on animals.

“The case of Fukushima plant workers is a different story. Some of them have already topped exposure limits. It is necessary to strictly monitor them to see if there is any impact."
