Massive whale graveyard discovered in Indian Ocean supports unique ecosystems

An extraordinary whale graveyard, potentially holding over ten million whale carcasses, has been discovered deep within the Indian Ocean. Located in the Diamantina Trench off the coast of southwestern Australia, this V-shaped depression on the seafloor plunges to depths of up to 7,000 meters and stretches for approximately 1,200 kilometers.

It was a complex feeling, a bit scary, but also fascinating from a research perspective. It involved dead bodies, but at the same time, vibrant, living ecosystems.

Researchers estimate the oldest fossils found at the site to be around 5.3 million years old. The discovery includes remains of deep-sea beaked whales, an Antarctic blue whale, and a skeleton from the extinct whale species *Pterocetus benguelae*. A previously unknown whale species, named *Pterocetus diamantinae* after the location, was also identified.

It is a fracture zone that goes down into the deep and becomes like a funnel on the bottom.

Marine biologist Björn Källström explained that the trench acts like a funnel, drawing whales down into its depths. While beaked whales are adapted to deep dives, the extreme pressure at such depths poses a significant risk, leading to their demise. The whale carcasses create unique ecosystems in the otherwise barren deep-sea environment, supporting life in what Källström describes as a "deep-sea desert."

And if the bottom looks like a funnel, the whales will sort of fall into it, deeper and deeper.
