Creatures such as the tube worms and other species that live near the hydrothermal vents are termed extremophiles, which are life forms that inhabit environments human beings consider "extreme"--habitats that seem to be unsuitable for life.
In February 2011, Salon reported that scientist Samantha Joye of the University of Georgia found sea floors in the Gulf that were still coated with oil from the spill--and oil-choked sea creatures including dead crabs, tube worms and brittle stars littered the ocean floor.
Marine biologists and environmentalists worry that the oil is doing significant harm to populations of tube worms, tiny crustaceans and mollusks, single-cell organisms and other underwater life forms that shape the building blocks of the marine food chain.
Anti-fouling coatings are also being applied in tidal and wave power installations, which offer a wide range of surfaces for marine organisms such as algae, barnacles, mussels and tube worms to adhere to.
In its lifetime, the little submersible has located a lost hydrogen bomb in the Mediterranean Sea, explored deep-sea hydrothermal vents (where it collected evidence of about 300 previously unknown life forms, including giant tube worms), surveyed and helped photograph the Titanic, and accidentally gave scientists vital feedback about decay in the deep.

Clams the size of dinner plates that reek of sulfur, tube worms that grow up to 8 feet and ghostly crabs and eel-like fish share the narrow but surprisingly rich life zone around the vents.
The hulls of oceangoing ships traditionally have been coated with toxic paints containing heavy metals such as copper and tributyltin, active ingredients that work by poisoning hull-hugging marine organisms such as barnacles, tube worms, and algae.
