Osedax worms, also known as bone worms, zombie worms, or bone-eating worms, were first discovered on a whale carcass in 2002.
There are more than 10 species that can be found in oceans across the globe at depths of up to 4 km. They belong to the worm family Siboglinidae (beard worms). Like all species in the family, they have no mouth, anus, or gut.
Typically, bone-eating worms grow up to 3-4 cm long. They consume whale bones, prompting many marine biologists to believe that they co-evolved 45 million years ago, branching out from their cousins that used chemosynthesis to obtain food. |
