Riftia pachyptila
Riftia pachyptila, commonly known as giant tube worms, are marine invertebrates in the phylum Annelida related to tube worms commonly found in the intertidal and pelagic zones. Riftia pachyptila live on the floor of the Pacific Ocean near black smokers, and can tolerate extremely high hydrog…
What are adaptations does tube worm have?
What adaptations do giant tube worms have? Three adaptations of Riftia pachyptila are the ability to retract their plume, chemosynthesis, and heat resistance. The tube worm pulls in it's plume to protect it from shrimp and crabs.
Are tube worms animals or plants?
Riftia pachyptila, commonly known as the giant tube worm, is a marine invertebrate in the phylum Annelida (formerly grouped in phylum Pogonophora and Vestimentifera) related to tube worms commonly found in the intertidal and pelagic zones.
Can tube worms survive land?
The tube worms can only live where there is no light: zones 3, 4, and 5. B) C) Only in the top-most two zones so the bacteria can use the light for photosynthesis. In any zone in the ocean, provided it was not too cold and there is enough oxygen in the water They tube worms are suited to live in the halad zone only, where there is
Are tube worms herbivore?
The pogonopherans found in soft sediments at great depths constitute a group of gutless benthic worms that are related to the tube worms of hydrothermal vents. For a long time their form of nutrition was an enigma and much debated. Recently, it has been discovered that they depend on symbiotic sulfide oxidizers, or in one case methane oxidizers.
What adaptation keeps tube worms alive?
A trophosome is an organ that houses symbiotic bacteria in tube worms. This organ replaces their digestive system, because the symbiotic bacteria living in the trophosome can provide organic nutrients and other compounds for energy and growth.
How do tube worms protect themselves?

What was so unusual about the giant tube worms?
The organisms that live near these vents are unique because, unlike all other living things on earth, they do not depend on sunlight for their source of energy. Instead, they feed on tiny bacteria that get their energy directly from the chemicals in the water through a process known as chemosynthesis.
How do Riftia pachyptila survive?
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. An entire unexpected ecosystem powered by chemosynthesis thrives in the dark depths of the ocean.
How do giant tube worms breathe?
The tubeworms' feather-like red plumes act as gills, absorbing oxygen from seawater and hydrogen sulfide from vent fluids.
Do giant tube worms have eyes?
The giant tube worm has no eyes, mouth, or stomach. Life In the Deep: Giant tube worms, Riftia pachyptila, live more than a mile beneath the surface of the ocean and near hydrothermal vents. They can grow up to eight feet long.
Do tube worms have gills?

Do giant tube worms have predators?
Few deep sea creatures such as deep sea crabs and shrimps, large brown mussels and giant clams are predators of giant tube worms (they feed on plumes).
How do giant tube worms feed?
Tubeworms do not eat. They have neither a mouth nor a stomach. Instead, billions of symbiotic bacteria living inside the tubeworms produce sugars from carbon dioxide, hydrogen sulfide, and oxygen.
How giant tube worms survive at hydrothermal vents quizlet?
How do they feed ? absorb nutrients produced by the bacteria in their tissues. About 285 billion bacteria per ounce of tubeworm tissue. Haemoglobin in the tube worm combines with hydrogen sulfide and transfers it to the bacteria living inside the worm.
What do the giant tube worms need in order to perform chemosynthesis?
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.
How do tube worms grow?
They are one of the fast growing organism on earth. The adult tube worms are attached and when a vent stops venting they will die. The sexes are separate and a fertilized egg grows into a larval form. They produce a larval form which swims in the water for up to a month and then will settle to colonize a new vent site.
What is the green spongy tissue of a giant tube worm?
Giant tube worms have green-brown spongy tissue called trophosome, made of specialized cells filled with microorganisms (285 billion bacteria per ounce of tissue). Plume collects oxygen, hydrogen sulfide and carbon dioxide from the water. Bacteria convert these molecules into carbohydrates (sugar), which giant tube worms use as a source of food.
What are giant tube worms?
Giant tube worms are marine invertebrates that belong to the family of polychaete annelid worms. These unusual creatures were discovered in 1977. Since that time, more than 300 new species of giant tube worms were identified. Giant tube worms can survive in the complete darkness, on a depth of 5.280 feet. They inhabit areas near the hydrothermal vents (openings in the ocean floor that look like giant chimneys) that release extremely hot water filled with various minerals. Since they live in remote areas with harsh environmental conditions, giant tube worms are not threatened by humans.
How long do giant tube worms live?
Giant tube worms grow rapidly and quickly colonize new areas. They reach sexual maturity before the age of 2 years. Exact lifespan of giant tube worms is unknown.
Why is plum red?
Plume is red colored because it contains great quantity of complex, oxygen-carrying pigment, better known as hemoglobin, which is red colored. Giant tube worms live in symbiosis (mutual beneficial relationship) with microorganisms.
Do giant tube worms have a mouth?
Males and females release eggs and sperm cells directly into the water (by retracting their plumes). Larvae are mobile and equipped with mouth and gut, because they need to collect bacteria that are essential for the second part (sedentary) of their life. Larvae swim until they found suitable ...
Do tube worms have eyes?
Tube offers protection against predators. Giant tube worms do not have eyes, mouth, stomach and legs. Giant tube worms spend their life firmly attached to the seafloor. Some species develop root-like structures to ensure stronger connection with substrate. Upper part of the body is called "plume".
