World's largest whale graveyard found by sub at bottom of ocean

World World's largest whale graveyard discovered by sub at bottom of ocean: "Completely unexpected" June 10, 2026 / 12:45 PM EDT / CBS/AFP Add CBS News on Google The world's largest whale graveyard has been discovered at the bottom of the Indian Ocean by Chinese scientists, who found that the vast expanse of both new and ancient carcasses supports huge communities of deep-sea life.It is the deepest and oldest known whale graveyard on Earth, according to research published in the journal Nature on Wednesday, with some fossils dating back 5.3 million years.From inside a small submersible, the Chinese researchers saw many strange animals — many believed to be new to science — living off the whale carcasses.A new, though extinct, species of whale was also identified among the nearly 500 skeletons that were found up to 7,000 meters deep along a 1,200-kilometer corridor of bones in the Indian Ocean west of Australia.Lead study author Xiaotong Peng of the Chinese Academy of Sciences told AFP that the researchers were "astonished" when the scale of their discovery became clear.It was known that when whales die and drop to the seafloor, their sunken bodies — called "whale falls" — provide a source of food to deep-sea creatures."But discovering a necropolis of this scale was completely unexpected: the size of distribution, the depth and the age range were far beyond anything we had imagined," Xiaotong Peng said.

"Truly incredible experience"For the discovery, the Fendouzhe submersible carried out 32 dives in 2023 — though what it found was only r...
