Blue whales, Earth's largest creatures, have returned to a part of the Indian Ocean where they were once decimated by whaling. Researchers in the Seychelles captured footage of these magnificent creatures in 2020 and 2021. Recent underwater audio recordings of their hauntingly beautiful low-frequency songs throughout the year have revealed their prolonged presence, suggesting potential breeding activities. This rediscovery is hailed as a ‘conservation win’ after decades of commercial whaling, which severely reduced blue whale populations. The end of mass-scale hunting has allowed them to rebound; however, their numbers remain small, and they are still classified as endangered. The Seychelles' role as a habitat for blue whales is a cause for excitement and underscores the importance of conservation efforts.
