What environment do Pompeii worms live in?
hydrothermal vents
Pompeii worms were initially discovered by French researchers in the early 1980’s and are described as deep-sea polychaetes that reside in tubes near hydrothermal vents along the seafloor. They can reach up to 5 inches in length and are pale gray with red tentacle-like gills on their heads.
How do Alvinella pompejana survive?
A. pompejana specifically inhabits chimney walls of hydrothermal vents on the East Pacific Rise. To survive, Alvinella has developed numerous adaptations at the physiological and molecular levels, such as an increase in the thermostability of proteins and protein complexes.
How do Pompeii worms eat?
Thought to subsist on vent microbes, the Pompeii worm pokes its head out of its tube home to feed and breathe. Its posterior end is exposed to extreme temperatures; the anterior end stays at a much more comfortable 22 °C (72 °F).
Why are Pompeii worms called that?
Pompeii worms get their name from the Roman city of Pompeii that was destroyed during an eruption of Mount Vesuvius in AD 79.
How do these giant tube worms survive in the thermal 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 Pompeii worms sessile?
The species are among the most abundant and common sessile organisms of the vent system, although they colonize distinct areas with different chemical and physical conditions in terms of pH, temperature, level of hydrogen sulphide and dissolved oxygen (Hessler et al., 1988; Desbruyères et al., 2000; Le Bris et al..
Are Pompeii worms invertebrates?
Alvinella pompejana, the Pompeii worm, is a species of deep-sea polychaete worm (commonly referred to as “bristle worms”)….

How are tube worms adapted?
One of the remarkable adaptations contributing to the ability of tubeworms to thrive in chemosynthetic habitats involves their specialized hemoglobin molecules that can bind oxygen and sulfide simultaneously from the environment and transfer it to the bacterial symbionts.
What adaptations do giant tube worms have to live near deep sea vents?
How do tube worms survive?
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.
Why are polychaete worms transparent?
A common feature is that many of the worms that inhabit the open ocean are transparent. This is because there is no concealment in the midwater zone, and so some worms like the green bomber worm have adapted to use bioluminescence as a way to startle and distract predators.
How do giant tube worms survive?
Where do tube worms like to live?
Giant tube worms have been found throughout the Pacific Ocean where deep sea hydrothermal vents have been discovered. The average depth of these vents is 5,000 feet (1,500 meters). Entire communities of shrimps and crabs have been found living around these giants.
How do polychaetes survive in the wild?
The researchers suspect that these polychaetes survive by feeding on free-living bacteria on the gas hydrate’s surface. They may also encourage the growth of their own bacterial food; their waving parapodia create water currents along the surface of the hydrate, delivering fresh oxygen for themselves and the bacteria.
