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 marine worm. Marine worms are found in several different phyla, including the Platyhelminthes, Nematoda, Annelida (segmented worms), Chaetognatha, Hemichordata, and Phoronida. For a list of marine animals that have been called "sea worms", see sea worm.

Many of these worms have specialized tentacles used for exchanging oxygen and giving out carbon dioxide, plus such arms may be used for reproduction.

Some marine worms are tube worms, of which the giant tube worm lives in waters near underwater volcanoes, and can withstand temperatures up to 90 degrees Celsius or about 194 degrees Fahrenheit.

Some worms can live in the trench. These worms were first discovered in the Pacific Ocean off the Galapagos Islands.
