Whale kill mystery
RESEARCHERS may never solve the deaths of 18 rare whales whose carcasses were found floating near Alaska’s Kodiak Island. The 10 fin whales and eight humpbacks were found from late May to early July. Most were too decomposed for sampling. Both species feed close together and scientists speculate the animals might have eaten something toxic in waters that were significantly warmer than average at the time. A muscle tissue sample is being tested for the possibility of radionuclides from the 2011 Fukushima nuclear disaster. Scientists have also looked at other possibilities.
