What unusual deep-sea life thrives on the whale carcasses?

Question

Accepted Answer

Deep-Sea Ecosystems Flourish on Whale Carcasses in the Indian Ocean

Chinese scientists have discovered the world's largest whale graveyard in the Indian Ocean, revealing that whale carcasses serve as a vital food source supporting diverse communities of deep-sea life. This extensive graveyard, located up to 7,000 meters deep along a 1,200-kilometer corridor, contains nearly 500 skeletons, some dating back 5.3 million years. The discovery was made using the Fendouzhe submersible during 32 dives in 2023, uncovering a vibrant ecosystem sustained by these ancient remains.
Diverse Fauna Found on Whale Falls

Researchers observed a remarkable array of animals thriving on the whale carcasses, including jellyfish, worms, snails, crustaceans, brittle stars, and bivalves. These creatures have adapted to utilize the whale falls as a primary source of sustenance in the deep ocean. The sheer abundance of these carcasses, estimated to be over 10 million in the Diamantina Zone, provides a substantial and long-lasting food supply for these organisms.
Potential for New Species Discovery

Many of the deep-sea animals found living on the whale carcasses are believed to be new to science. While specific details about these potential new species are not elaborated upon, their presence highlights the unique biodiversity supported by these deep-sea ecosystems. The discovery of these organisms underscores the significant role whale carcasses play in fostering life in otherwise barren environments.
Whale Carcasses as Connectors of Deep-Sea Communities

The presence of whale carcasses creates habitats that may help connect different deep-sea communities, much like hydrothermal vents. The soft tissues and lipids within an estimated 6.7 million tonnes of sequestered carbon from these carcasses provide an immense source of energy. This suggests that whale falls act as crucial ecological hubs, facilitating the exchange of life and resources across the deep ocean floor.
