A tubeworm is any worm-like sessile invertebrate that anchors its tail to an underwater surface and secretes around its body a mineral tube, into which it can withdraw its entire body. Tubeworms are found among the following taxa : Annelida
Annelid
The annelids, also known as the ringed worms or segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones a…
What does a giant tube worm eat?
The acquisition of a symbiont by a host can occur in these ways:
- Environmental transfer (symbiont acquired from a free-living population in the environment)
- Vertical transfer (parents transfer symbiont to offspring via eggs)
- Horizontal transfer (hosts that share the same environment)

Why are tube worms so important?
Certain species (e.g., tube worms and mussels) can establish a symbiotic relationship with these bacteria and not only survive, but thrive in deep sea seeps. These populations may provide the basis for diverse community in the seep environment.
How do tube worms help the environment?
Deep-sea tubeworms The worms host these bacteria in a specialized organ known as a trophosome. The tubeworm Lamellibrachia luymesi can be found at cold seeps in the Gulf of Mexico where it acts as an ecosystem engineer, creating habitats for other deep-sea species.
How do tube worms work?
The tubeworms' feather-like red plumes act as gills, absorbing oxygen from seawater and hydrogen sulfide from vent fluids. This feat is accomplished by a special type of hemoglobin in their blood that can transport oxygen and sulfide at the same time (human hemoglobin transports only oxygen).
How do tube worms make food?
These giant worms lack a mouth, gut and anus. In fact, they have no digestive system at all. But they do need food and oxygen. They get their food from special symbiotic bacteria that live inside their body in an organ called the trophosome, which is basically a sac crammed full of bacteria.
Do tube worms have brains?
Earthworms and all worms have a brain. It is connected to the skin of the worm and muscles, which helps the worm to move around. There are nerves extended from various parts of the body to the brain. They have around 302 nerve cells in their body.
Is tube worms a decomposer?
Worms are part of a special group of species that eat dead or decaying organic matter. They are called decomposers.
What bacteria does in tube worm?
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.
What organisms eat tube worms?
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).
Can tube worms swim?
As adults, giant tubeworms can swim through the currents.
How long do tube worms 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 do tube worms live?
The worms are being kept in ocean water with hydrogen sulphide pumped in to make the environment similar to that of a deep ocean vent. This gas, which is poisonous to most forms of life, provides food to the bacteria that live in the worms. The worms survive by periodically feeding on the bacteria.
How do the worms help bacteria?
Decomposition releases nutrients locked up in dead plants and animals and makes them available for use by living plants. Earthworms do this by eating organic matter and breaking it down into smaller pieces allowing bacteria and fungi to feed on it and release the nutrients.
How big do tube worms get?
Click to see full answer. Besides, how do tube worms survive? These giant tube worms grow up to eight feet (over two meters) in length and have no mouth and no digestive tract. They depend on bacteria that live inside them for their food. The bacteria actually convert the chemicals from the hydrothermal vents into organic molecules ...
Do tubeworms eat crabs?
The tubes help protect the worms from the toxic vent chemicals and from predators such as crabs and fish. 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. Click to see full answer.
What are tube worms?
Tube Worms. Tube worms are oddities that range from aquarium-sized feather dusters to giants grouping on the ocean floor. They surround themselves with an outer tube that bears roots on one end and reddish plumes on the other.
Where do tube worms live?
They’ve also been studied near cold, or hydrocarbon seeps, in the Gulf of Mexico. These fissures allow water to rush downward and interact with rocks, which creates a mineral release. The uprush brings nutrients swirling around the tube worms and other deep-dwelling creatures.
How big do worms grow?
At the cold seeps, they may grow slowly over decades. At heat fissures, they mature rapidly to giant sizes of 8-15 feet. Categorization is also confusing. Some fall into the segmented worm group while others are closely related, but with a well-defined solid outer tube. Those that dwell along the ocean floor are sometimes grouped as “pogonophora,” which means beard-bearer in Greek.
Do tube worms have a mouth?
This protective outer layer harbors a spongy bacteria-filled interior. Some believe that while still young, tube worms have an underdeveloped mouth and digestive tract that forms the basis for adult survival. The deep-sea worms apparently lose this part of their anatomy with age. No Paywall Here!

Do whales have worms?
For the whale-dwellers, females harbor tiny male worms within their bodies. Once the carcass is consumed, the adult tube worms die. First, however, eggs are produced and released to gain a new start at another site.
What are vestimentiferan tube worms?
Vestimentiferan tube worms from hydrothermal vents provided the first indication that invertebrates can exploit organic matter production by symbiotic chemolithotrophic bacteria (sulfide-oxidizing bacteria, specifically; Cavanaugh, 1983 ). Previously, associations of sulfide oxidizers with various marine invertebrates and a ciliate had been noted, but not understood, as a source of organic matter. In the decades following the discovery of vestimentifera, symbioses with sulfide oxidizers have proven to be a very widespread phenomenon in benthic marine animals, and not only in animals associated with hydrothermal vents. Symbioses with methane oxidizers have also been observed, especially at hydrocarbon-methane seeps. The deep-sea mytilid bivalve, Bathymodiolus, even harbours both sulfide as well as methane oxidizers. 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. The symbiotic bacteria in these animals reside in a special organ, the trophosome, and they are supplied by oxygen as well as sulfide through the worms’ circulatory system. Symbioses involving chemolithotrophic bacteria have also been found in various marine invertebrates living in shallow waters. Hosts include bivalves (especially lucinid and thyasirid clams), gastropods, crustaceans, polychaetes, nematodes and oligochaete worms, in addition to two types of ciliates. Some of these animals are gutless and totally dependent on the production of organic matter by the symbionts, such as the bivalve Solenomya and some oligochaetes, whereas others combine organic substrates from their symbionts with more conventional food sources. These topics have been reviewed extensively (Bright, Lallier, 2010; Bright, Giere, 2005; Dubilier et al., 2008; Petersen, Dubilier, 2009; Stewart et al., 2005; Van Dover, 2000 ).
How do vents work?
Vents occur where tectonic spreading and subduction create fissures in the Earth's crust, allowing sea water to percolate through the crust and become heated by the mantle ( Figure 4 ). When this water percolates out through the crust again, it is rich in minerals and reduced compounds such as hydrogen sulfide. Water temperature is extremely high (200–400°C), and is prevented from boiling by the extreme pressure. It cools quickly, however, as it mixes with the ambient sea water that is typically ∼4°C. The mixture of sedimentary and hard substrate habitats that are characteristic of vent fields often support a large biomass of a very specialized fauna.
Which hosts gall-building parasitic copepods?
After molluscs, echinoderms constitute the second most important hosts for gall-building parasitic copepods ( Anton et al., 2013) ( Fig. 14.4 A and B ). Gall-building endoparasites of the genus Pionodesmotes infest echinothuriids.
