Giant squid killed … by sound

When giant squid were found dead off Spain about a decade ago, scientists suspected that powerful sound pulses from ships had harmed the animals. Now the evidence may be in.

The finding suggests noise pollution in the ocean is having a much broader effect on marine life than previously thought. Learn more here.
