The body is cylindrical, slender, naked, and superficially vermiform (worm-shaped). In spite of their slender, worm-like forms, shipworms possess the characteristic morphology of bivalves . The ctinidia lie mainly within the branchial siphon , through which the animal pumps the water that passes over the gills .

Nematodes are very small, slender worms. Most are free-living, often less than 2.5 mm long and some only about 1 mm. Many nematodes are microscopic. Some soil nematodes can reach up to 7 mm in length, and some marine species can reach up to 5 cm. Some are parasitic and can reach lengths of 50 cm or more. [42]
