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.
These worms have specialized tentacles used for exchanging oxygen and giving out carbon dioxide, plus they are 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.
Famous quotes containing the words marine and/or worm:
“People run away from the name subsidy. It is a subsidy. I am not afraid to call it so. It is paid for the purpose of giving a merchant marine to the whole country so that the trade of the whole country will be benefitted thereby, and the men running the ships will of course make a reasonable profit.... Unless we have a merchant marine, our navy if called upon for offensive or defensive work is going to be most defective.”
—William Howard Taft (1857–1930)
“A worm on the ear-of-wheat,
I am yet unrepentant,
for I know how the Lord God
is about to manifest, when I,
the industrious worm,
spin my own shroud.”
—Hilda Doolittle (1886–1961)
