The giant tube worm is a fascinating marine worm that lives in the extreme depths of the oceans, near hydrothermal vents. Discovered in the late 1970s, it has become a symbol of deep-sea ecosystems and life forms capable of surviving without sunlight.

The giant tube worm can grow over 6.5 feet in length and lives inside a rigid white tube that it secretes. It has a bright red plume rich in hemoglobin, used to capture the gases necessary for its survival.

The giant tube worm is mainly found in the Pacific Ocean, along mid-ocean ridges, particularly near hydrothermal vents in the East Pacific. Its distribution is closely linked to these extreme environments.

The giant tube worm lives at great depths, often between 6,500 and 9,800 feet, in close proximity to hydrothermal vents where water temperatures can reach very high levels. These environments are rich in chemicals but completely devoid of light.

Unlike most animals, the giant tube worm has neither a mouth nor a digestive system. It lives in symbiosis with bacteria that convert chemical compounds, such as hydrogen sulfide, into energy through chemosynthesis.

The giant tube worm reproduces by releasing its gametes into the water, where fertilization is external. The larvae then drift in the ocean before settling near a hydrothermal vent and developing their bacterial symbiosis.
