Study ups narwhal numbers.

The revised count is particularly encouraging because the narwhal – whose tusks inspired the ancient unicorn myth – was recently identified in an international study as the animal most vulnerable to the impacts of retreating Arctic sea ice, a phenomenon generally viewed as deadliest for polar bears.

Previous population estimates in the Canadian sounds and inlets at the north end of Baffin Island pegged the number of narwhals at no more than 30,000. The latest inventory – which employed a combination of aerial surveys, tracking of tagged animals and new methods for more accurately estimating the number of unseen, diving whales – raises the total estimate to 60,000
