What are zombie worms age?

Zombie worms, scientifically known as Osedax, are marine polychaete annelids that primarily feed on the bones of dead marine animals, such as whales. They can live for several years, but their exact lifespan can vary depending on environmental conditions and food availability. The term "zombie worms" refers to their unique feeding habits rather than their age, as they consume the organic material within bones rather than the bones themselves.
