– Researchers studying whales in the western Indian Ocean stumped. They recorded a whale song they had never heard before, described by one as a “slow, throbbing ballad” New York Times. After some underwater drowsiness, they report happy discovery in the journal Endangered species research: The song is about a previously unknown population of blue whales. This is especially good news that the blue whale, which grows to a large size, has been listed under the Endangered Species Act, a post of clay notes. After being hunted on the verge of extinction, the number of blue whales in existence is estimated to be somewhere between 10,000 and 25,000. It is unknown at this time what he will do after leaving the post.
“Finding a whale song in your data was quite significant, which was completely unique, never known and known as the Blue Whale,” says Salvatore Serchio, study co-author of the African Aquatic Conservation Fund’s CTCIAN program. Blue Whale usually explains to Science Daily that even for low pitch songs each population has its own version. That’s why researchers were able to identify the new group, which may be a unique subspecies. “It’s like listening to different songs in one genre – Stevie Ray Vau vs. BB. King,” says Serchio Times. “It’s all blues, but you know the different types.” Researchers say the search makes it even more important to protect whales with shipping and carbon emissions regulations.
