What Do Whale Worms Eat? Why Are Whale Remains Able to Support So Much Life? (Site 1)

Whale carcasses that sink to the ocean floor play a crucial role in supporting a diverse array of marine life. These remains become a feast for a variety of scavengers, including whale worms. So, what do whale worms eat and why are whale remains able to support so much life?

Whale worms, also known as osedax, are marine polychaete worms that have evolved to feed on the bones of dead whales. These worms possess specialized mouthparts that allow them to bore into the bones, extracting nutrients from the collagen-rich tissues. They form a mutually beneficial relationship with symbiotic bacteria that aid in the digestion of these proteins. The whale worms benefit from the nutrients obtained, while the bacteria receive a constant food source.

Whale remains act as a source of sustenance for a multitude of organisms, ranging from bacterial communities to large scavengers like hagfish and sleeper sharks. The process starts with scavengers such as hagfish and sleeper sharks, which consume the soft tissues of the whale. As the carcass decomposes, it sinks to the seafloor, creating a unique habitat for a variety of organisms. This includes the whale worms, which colonize and consume the bones. Other organisms, such as isopods and amphipods, feed on the whale worms and the bacteria they host. This chain of consumption continues, supporting a complex food web that can last for years or even decades.

The ability of whale remains to support such a high level of life can be attributed to the nutrient-rich nature of the carcass. Whales are massive creatures, and their bodies contain a significant amount of energy and nutrients. When these remains sink to the seafloor, they become a concentrated food source that can sustain a multitude of organisms. The slow decomposition process ensures a continuous supply of nutrients over an extended period.
