Shipworm anatomy reveals the typical organs of a bivalve mollusk, although with dimensional or positional peculiarities due to the thinness and length of the occupied space. Furthermore, some structures find no equivalent in other bivalve groups. Gills are divided in two halves, the anterior one of small size, the posterior one much more developed.
Teredo navalis, commonly called the naval shipworm or turu, [2] is a species of saltwater clam, a marine bivalve mollusc in the family Teredinidae. This species is the type species of the genus Teredo .
Teredo is a genus of highly modified saltwater clams which bore in wood and live within the tunnels they create. They are commonly known as "shipworms;" however, they are not worms, but marine bivalve molluscs (phylum Mollusca) in the taxonomic family Teredinidae.
The taxonomic term Bivalvia was first used by Linnaeus in the 10th edition of his Systema Naturae in 1758 to refer to animals having shells composed of two valves. [3] More recently, the class was known as Pelecypoda, meaning "axe-foot" (based on the shape of the foot of the animal when extended).

The excavations within the wood are of varying lengths and diameters, and it appears to be the case that the whole of the life cycle of this species of shipworm takes place in mid-ocean, with larvae settling on the timber and reproducing there as the wood slowly drifts along on the current. [5]
An example of a marine worm, the Parborlasia corrugatus lives at depths of up to 4,000 metres.. Any worm that lives in a marine environment is considered a water worm. Marine worms are found in several different phyla, including the Platyhelminthes, Nematoda, Annelida (segmented worms), Chaetognatha, Hemichordata, and Phoronida.
Lithoredo is a genus of shipworm native to the Abatan River in the Philippines.It contains a single species, Lithoredo abatanica, described in June 2019. [1] The species is unusual because, unlike other shipworms which mainly bore into wood, it tunnels into and excretes limestone.
