How long do giant tube worms live?
Giant deep-sea worms may live to be 1000 years old or more. In the depths of the ocean, life can extend far beyond its usual limits. Take the tube worm Escarpia laminata: living in an environment with a year-round abundance of food and no predators, individuals seem to live for over 300 years.
What ocean zone do giant tube worms live in?
