Researchers have recently added two new species to the five existing species of bone-eating worms, National Geographic reports. The new species are named Osedax antarcticus and O. deceptionensis and are likely just a few of many new species of bone-eating worms yet to be discovered in Antarctica, says marine biologist Thomas Dahlgren, a co-author of the study.

Bone eating worms survive by eating the skeletons of whales on the seafloor of the Antarctic continent and several species have been known to feed on a single whale, leading the scientists to conclude that there are likely many more species of bone-eating worms yet to be found.
