Story summary

Disappearance of Osedax, the deep-sea "zombie worm," in the northeast Pacific may signal ecological distress caused by low oxygen linked to ocean warming.
Over more than a decade, researchers observed whale bones off British Columbia and found no evidence of Osedax, which normally decomposes whale carcasses.
The absence suggests expanding oxygen minimum zones could disrupt whale-fall ecosystems and threaten species such as Xylophaga, with ongoing monitoring planned to assess impacts.
