Dolphins are social, intelligent animals who rely on whistles and echolocation to hunt and reproduce. This means that noise generated from human activity such as drilling and shipping has the potential to negatively impact the health of wild dolphin populations. A study in the journal Current Biology published on January 12 demonstrates that dolphins “shout” when trying to work together in response to increasing underwater noise levels.
