Zombie worms vanished from B.C. coast, alarming scientists studying deep-sea ecosystem health.

A rare deep-sea creature known as the "zombie worm" has disappeared from the B.C. coast, raising concerns among researchers at the University of Victoria. The worm, which feeds on whale bones and plays a key role in deep-sea ecosystems, has not been observed in recent surveys, prompting fears about environmental changes affecting marine biodiversity. Scientists are investigating potential causes, including ocean warming and shifting deep-sea conditions.
