California blue whales bounce back to near historic numbers
Researchers believe that California blue whales have recovered in numbers and the population has returned to sustainable levels.
Scientists say this is the only population of blue whales to have rebounded from the ravages of whaling.
The research team estimate that there are now 2,200 of these giant creatures on the eastern side of the Pacific Ocean.
