It's Alive! First Living Giant Sulfur-Powered Shipworm Found in Philippines

Despite their name, shipworms are marine bivalve mollusks that usually munch on wood which has washed into the ocean. The alien-looking recently-discovered organism, Kuphus polythalamia, has been classified as a giant shipworm, although it lives in hydrogen sulphide gas-emitting mud rather than wood. When researchers opened its white tube-like shell, they were surprised by the appearance of the mollusk: unlike other shipworms, it was jet-black and extremely muscular for its life in a shell. Scientists hope to explain how shipworms evolved from a wood-eating organism to one that gets energy from noxious fumes of sulfur.
