Riftia pachyptila, commonly known as the giant tube worm, is a marine invertebrate in the phylum Annelida. It inhabits hydrothermal vent ecosystems on the Pacific Ocean floor, where temperatures range from 2 to 30 °C. This species can tolerate extremely high hydrogen sulfide levels and relies entirely on symbiotic sulfur-oxidizing bacteria housed in its trophosome for nutrition. These worms can grow up to 3 meters in length, with tubular bodies reaching a diameter of 4 cm, making them one of the most iconic organisms in deep-sea vent ecosystems.
