Researchers reveal a vast whale graveyard in the southeastern Indian Ocean, extending to depths of 7,000 metres and spanning hundreds of kilometres. The site hosts hundreds of fossil skeletons and five modern whale falls, highlighting a thriving deep-sea ecosystem that feeds on whale carcasses. The findings, published in Nature, deepen understanding of deep-sea life and whale evolution.
