How do tube worms survive?
How Giant Tube Worms Survive at Hydrothermal Vents. In a process called chemosynthesis, symbiotic bacteria inside the tubeworm use hydrogen sulfide spewed from the vents as an energy source for themselves and for the worms.
Are tube worms producers?
Chemosynthetic bacteria are the primary producers in these communities. They exist both as free-living organisms and in a symbiotic relationship within the cells or body of other organisms, such as the tube worm Riftia pachyptila (Figure 1). The anatomy of the tube worm Riftia pachyptila.
Are tube worms animals or plants?

How long can a tube worm live?
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.
How big does a tube worm get?
eight feet
Can tube worms move?
The bacteria actually convert the chemicals from the hydrothermal vents into organic molecules that provide food for the worm. Although the worms have no eyes, they can sense movement and vibrations and will retreat into their protective tubes when threatened.
How much can a giant tube dwelling worm from a hydrothermal vent grow in a year?
The tubeworms get a steady supply of organic carbon and can grow prolifically, tacking on roughly 31 inches (80 centimeters) of white tube to their bodies every year.
What kind of living things are able to survive in the vent ecosystem?
These specialized bacteria form the bottom of the deep hydrothermal vent food web, and many animals rely on their presence for survival, including deep-sea mussels, giant tube worms, yeti crabs, and many other invertebrates and fishes.
How tube worms get their energy?
They are a bit like photosynthetic plants, but instead of using energy from light (like plants do to make food from carbon dioxide), they use energy from chemicals present in the cold seeps and hydrothermal vents. Tubeworms use hydrogen sulfide as an energy source, which is the same chemical emitted by a rotten egg.
How do tube worms turn toxic water into food?
These bacteria make energy by combining hydrogen sulfide with oxygen (also supplied by the tube worms) to make sulfur, water and energy. The bacteria then uses this energy to convert carbon dioxide into food just like plants use energy from the sun to make food.
How much do tube worms weigh?
Facts about the giant tube worm (Riftia pachyptila) include that its average weight is 0.10-1.55 oz (2.75 to 44.35 g) and has a length of up to 8 ft (2.5 m).
Why do chemosynthetic bacteria live in tube worms?
These animals have no gut but get their food from chemosynthetic bacteria living in their tissues. The tube worms extract hydrogen sulfide form the vent water transferring it to an organ containing bacteria, here, the bacteria oxidize the hyrogen sulfide and turn it into food that can be used by the tube worm.
Is a deep sea tube worm a Heterotroph?
Its metagenome shows the presence of genes for the oxidative TCA cycle indicating the ability to live as heterotrophs outside the host. This points to a highly versatile bacterium capable of surviving in the biofilms of hydrothermal vents and adjacent deep sea as well as thriving under host control as endosymbionts.
