After 40 Years, a Blue Whale Population Bounces Back

6:26 minutes

It took four decades, but after being hunted to near-extinction, the California blue whale population has finally bounced back. According to a new paper in Marine Mammal Science, these behemoths (found primarily along the coasts of California and Mexico) have reached 97 percent of their original population size. Researcher Trevor Branch discusses the conservation strategies that helped bolster the population and whether they can be applied to other threatened species.
