What are zombie worms?

Zombie worms (Osedax roseus) eat away at the bones of a dead whale that has fallen to the seafloor in Sagami Bay, Japan. These bizarre worms rely on whale bones for energy and are what scientists call “sexually dimorphic”—the male and female forms are markedly different.

How do zombie worms reproduce?

They found that females started to spawn eggs six weeks after settlement. This rapid sexual maturation of females, alongside the male dwarfism which was observed, enables the worms to reproduce effectively in the food-rich, but highly isolated habitat of whale bones.

Do worms eat bones?

Osedax: bone – eating worms Various species are capable of colonizing a broad array of bones from fish, marine mammals, birds, turtles, and terrestrial mammals. These worms can consume bones very quickly, removing visual evidence of a sunken whale skeleton in as little as a decade.
