What are giant tube worms?
Giant tube worms are huge worms that live in hydrothermal vents or openings on the ocean floor, though which hot spring water and minerals flow out. The worm lives inside a tube which is attached to a hard surface like a rock. The tube is made of a hard substance which protects the worm from predators and the poisonous chemicals of the vent. Tube worms have bright red plumes which they withdraw into the tube when an enemy appears. Since they live mainly on the ocean floor, you are unlikely to see one though!
