Blue Whales Bounce Back
A new study reveals that the population of Californian blue whale has bounced back to levels nearly as high as before commercial whaling threatened to make the species extinct.
Writing in Marine Mammal Science, researchers from the University of Washington say California blue whales are now at 97 per cent of their historical levels
The research team estimate that there are now 2,200 of these giant creatures on the eastern side of the Pacific Ocean. Blue whales grow to 33m in length and weigh as much as 190 tonnes.
'It’s a conservation success story,' said Cole Monnahan, the study’s lead author and a doctoral student at the University of Washington.
However, other populations of blue whales - which were much more heavily fished - are still at dangerously low levels.
