For almost any object in the sea, there’s a creature who will feed on it – even if it’s a whale skeleton or a shipwreck. Though not related to one another, boneworms and shipworms share the remarkable ability to locate their meals in the vast ocean. Boneworms consume the bones of mammals, fish, reptiles and other animals, while shipworms – actually a type of mollusk – use their tiny shells to burrow into the wood of wrecked ships, trees adrift, or other wooden structures in the sea. Despite having neither stomachs nor mouths, both boneworms and shipworms have symbiotic bacteria in their gut that release nutrients from the bones or wood which these “worms” absorb as food.
