Scientists have discovered the world’s largest whale graveyard in the Diamantina fracture zone of the south-eastern Indian Ocean.
The find is significant because these ancient remains create long-lasting food sources that foster rare deep-sea biological communities. This process allows life to thrive in the extreme conditions of the ocean floor, far removed from the sunlight of the surface.
The site is located approximately seven kilometers below the ocean surface [1]. Researchers identified whale bones at the site that are as old as 5.3 million years [2].
These carcasses provide a critical foundation for a distinct ecosystem. The decaying organic matter supports various organisms, including jellyfish, tube worms, and brittle stars [3]. Because the deep ocean is generally nutrient-poor, these concentrated deposits of bone and tissue act as biological hotspots, islands of life in a vast aquatic desert.
The discovery occurred within the Diamantina fracture zone [4]. While some reports incorrectly placed the site in the Pacific Ocean, verified data confirms the location is within the Indian Ocean [4].
The presence of such a massive accumulation of remains suggests that the area has served as a natural collection point for whale carcasses over millions of years. This geological trap has preserved a record of marine life and provided a steady stream of energy for the scavengers and specialists that inhabit the depths [3].
“The site is located approximately seven kilometers below the ocean surface.”
The discovery highlights the role of 'whale falls' in sustaining deep-sea biodiversity. By providing a concentrated source of carbon and nutrients in an otherwise barren environment, these graveyards function as essential evolutionary hubs for specialized species, offering insight into how life persists in the planet's most extreme habitats.
