NYTimes: A New Population of Blue Whales Was Discovered Hiding in the Indian Ocean

The covert cadre of whales, described in a paper published last week in the journal Endangered Species Research, has its own signature anthem: a slow, bellowing ballad that’s distinct from any other whale song ever described. It joins only a dozen or so other blue whale songs that have been documented, each the calling card of a unique population.

“It’s like hearing different songs within a genre — Stevie Ray Vaughan versus B. B. King,” said Salvatore Cerchio, a marine mammal biologist at the African Aquatic Conservation Fund in Massachusetts and the study’s lead author. “It’s all blues, but you know the different styles.”
