But now is the time to find out. Both groups of worms survive without light, under intense pressures and in water that is often laced with acid and toxic gases. What we do. Pompeii worms were first discovered near the Galapagos Islands known for its famous turtles, the explorations of Charles Darwin, and the basis for Darwin’s theory of natural selection. The worm secrete mucus from its back which feeds the bacteria that protects it. In addition, they can withstand deep-ocean pressures and live in total darkness. 19. Future US, Inc. 11 West 42nd Street, 15th Floor, These worms can reach a length of 3 m (9 ft 10 in), and their tubular bodies have a diameter of 4 cm (1.6 in). They die if brought to the surface. 1992), and is known as being the most eurythermal metazoan (Haddad et al. They are known as extremophiles.. Pompeii worms get their name from the Roman city of Pompeii that was destroyed … Email Becky Oskin or follow her @beckyoskin. The Pompeii worm is a hairy-looking creature about as long as a hand … The worms live in burrows in and amoungst the coral. These bacteria survive in an extreme environment because of their morphology and chemistry. These float free of the coral and shed eggs and sperm into the seawater. Physiological adaptations he Pompeii Worm is a species of animal that can survive under pressure strong enough to crush a person and water hot enough to melt the skin off our bodies and therefore has gone through some pretty impressive physiological adaptations. The worms live in burrows in and amoungst the coral. Be the first to answer this question. 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. Such worms can be 2m long. "We didn't see the common hallmarks associated with other methane and hydrogen sulfide environments, such as various types of clams, mussels and bigger tubeworm species," says Paull. Once there, the AUV moved back and forth over the area, much like a person mowing a lawn. It lies 1250m beneath the sea, much deeper than the volcanoes in the Beaufort Sea. They were clustered around old mud flows. Please refresh the page and try again. Ambient temperature in their natural environment ranges from 2 to 30°C. The Galapagos Islands are made up of thirteen islands located in the Pacific Ocean off the coast of South America. In 2000, researchers found tubeworms that took 170-250 years to grow 2m long. The world's mud volcanoes are estimated to release 27 million tonnes of methane every year, about 5% of annual global emissions. They lived in cold seeps, another type of chemosynthetic environment, around the Gulf of Mexico. Working in October, the team had only a short window before the sea ice became too thick – making the area above the mud volcanoes inaccessible and potentially trapping them there. Superheated water — at temperatures of more than 750 degrees Fahrenheit (400 degrees Celsius) — spews from the vents. "It's like you're taking them from outer space and putting them on a shipboard lab," Lee said. The worms live in large colonies and their heads are protected by the rest of their bodies. The volcanoes are so large that you can only see a small part of them at any one time. I think it's likely that bacteria living inside the tubeworms are doing all the work. The mud has a viscous texture like the top of a very thick stew. One of the volcanoes, which was both the youngest and the most active, was almost devoid of worms. Pompeii worms live on volcanic vents located 2,500 meters below the surface of oceans. Each lasted two hours. But within 10 minutes of the hotter test, the worms crawled out of their tubes — an unnatural behavior — and by the end of the test, all 18 worms were dead. How do siphonophores move around in the ocean? Just better. Pompeii worms get their name from the Roman city of Pompeii that was destroyed during an eruption of Mount Vesuvius in AD 79. Where did pompeii worms get their names from. They have no eyes, no stomach and no anus. Answer. Instead, they somehow feed on the gases pumped out of the volcanoes. The whole setup is eerily similar to another mud volcano, on the other side of the world. The answer may lie in their behavior or in some specialized cellular biochemistry, or both.” (Lutz 2000) “The Pompeii worm is capable of withstanding temperatures as high as 105 ° C (Chevaldonne et al. In 2013 a team of scientists from around the world decided to take a closer look. The pompeii worm is a fuzzy gray animal with scarlet gills on its head. Please deactivate your ad blocker in order to see our subscription offer. These four-inch-long worms attach themselves to hydrothermal vents, where they bask in 80 degree-Centigrade (176 Fahrenheit) heat and a melange of toxic, Earth-born chemicals. antifreeze proteins (AFPs) lower the freezing point of its blood by a couple of degrees. The scientists discovered that the Pompeii worms survived the lower temperatures with no apparent tissue damage and little heat stress. Quite the same Wikipedia. Thank you for signing up to Live Science. Their tails are in the vents, which achieve temperatures up to 176 degrees Fahrenheit. Accès direct à 68900 torrents sans inscription et … Most siphonophores are active swimmers. Their heads however, poke out of the vents in order for the pompeii worms to capture prey. Changes in the sound waves reaching the ship suggested that large volumes of gas were bubbling up from the sea floor: a sign of volcanic activity. Pompeii worms makes a sort of papery colony attached to the chimneys of hydrothermal vents. However, they are distantly related to giant tube-dwelling annelid worms that are found near deep-sea hydrothermal vents. Pompeii worms insert their tails into the side of the vents, leaving their head exposed to the milder waters of 72°F [5]. Hydrates form when the intense pressures at depths of over 500m freeze the methane and water. It lives on deep-sea hydrothermal vents. Next the scientists wanted to see them close-up. The Pompeii worm pokes its head out of its tube home to feed and breathe in the cooler water. Armed with this, the worm grows a centimetre thick thermal blanket across its back that is composed of colonies of filamentous bacteria. A small mechanical arm attached to the ROV grabbed some of these worms and carried them back to the surface. 1995 Scientists have discovered that the bacteria insulate the worms from the extreme heat of the vents, and the worms secrete mucus from glands on their backs to … Pompeii worms are theworld's most heat tolerant animal, living among hydrothermal vents, and can withstand up to 176 degrees Fahrenheit. Tripod fish have two types of specialized fins. But how they do it is only just starting to be revealed. "This doesn't mean it cannot 'adventure out' in higher temperatures, maybe 60 degrees Celsius, but then it would not be permanent. "I personally think that that's because the top of the volcanoes are churning over too fast for worms and other animals to accumulate there.". The worms were primarily found on the flat tops of the mud volcanoes, not on the slopes. Pompeii Worms live on hydrothermal sea vents at the bottom of the ocean ranging from 6,500-10,000 ft. below sea level These worms are extremophiles that thrive within hydrothermal vents located in the depths of the Pacific Ocean. Be the first to answer! Firstly, the Pompeii Worm makes paper like tube colonies that are heat resistant and give it somewhere to hide away from predators. Can survive: The aging process. Interestingly, the tube worms seem to prefer some areas of the volcanoes over others. 20. Scientists from the ArcticNet project were on a research ship, using sonar to map part of the Beaufort Sea, which lies north of Canada and close to Alaska. New York, Mon - Sat 8.00 - 19.00; 1010 Moon ave, New York, NY USA +1 212-226-31261 Its posterior end is exposed to extreme temperatures; the anterior end stays at a much more comfortable 22°C. The team had only a short window before the sea ice became too thick. 19. Attaching themselves to black smokers, the worms have been found to thrive at temperatures of up to 80°C (176°F), making the Pompeii worm the most heat-tolerant complex animal known to science after the tardigrades or water bears, which are able to survive temperatures over 150ºC. [6] Colonies of filamentous Proteobacteria form a protective coating over the worm's mucus glands [7]. The ROV's cameras revealed vast thickets of worms, "When clay minerals get buried they are exposed to increasing pressure and temperature," says Paull. A genetic analysis of the Beaufort tubeworms shows that they are closely related to siboglinid tubeworms living on the Håkon Mosby mud volcano, in the Norwegian Arctic. Normal volcanic eruptions can be triggered by earthquakes and shifting tectonic plates. How do some organisms survive extreme cold? But earthquakes are rare in the Arctic. The Pompeii worm makes its home in a boiling hot, deadly sulfurous soup of heavy metals, at a pressure depth that would crush a man (think of the Hulk squeezing a tube of toothpaste). The head extends out of the worm’s body to eat and breathe but is generally protected from the extreme conditions that the worms live in. The Pompeii worm (Alvinella pompejana) is a deep-sea polychaete worm found only at hydrothermal vents in the Pacific Ocean.Discovered in the early 1980s by French researchers, Pompeii worms are most famous for the current belief that they are the "hottest" animals on Earth. Pompeii, preserved ancient Roman city in Campania, Italy, that was destroyed by the violent eruption of Mount Vesuvius in 79 CE. The most likely culprits were mud volcanoes. Their cell wall is composed of polysaccharide that doesn’t melt in high temperature. Answer and Explanation: Pompeii worms eat microscopic bacteria that grows along deep-ocean trenches where geologic activity brings energy to the sea bottom. Alvinella pompejana, the “Pompeii worm” lives on active hydrothermal edifices at deep-sea vents of the East Pacific Rise.The physical and chemical patterns of its microhabitat were determined from temperature probe measurements, temperature time series, and on-board and shore-based chemical analyses based on discrete sampling (pH, H 2 S, CO 2, CH 4, S 2 O 2-3, Ca, Mg, Cu, Cd, Zn). R. pachyptila lives on the floor of the Pacific Ocean near hydrothermal vents, and can tolerate extremely high hydrogen sulfide levels. B.a process that uses oxygen to break down molecules to release energy.C.a process that breaks down molecules without the use of oxygen to absorb … In order to live within its harhsh home the Pompeii worm makes paper-like tube colonies attached to hydrothermal vent chimneys that are heat resistant. Why are the polychaete worms living near the underwater volcanic vent called Pompeii worms? Since that time, more than 300 new species of giant tube worms were identified. A lot of Earth's methane is trapped below the seabed as "gas hydrate", an ice-like crystal of methane and water. The first thing the team needed was a detailed map of the area. Pompeii worms are theworld's most heat tolerant animal, living among hydrothermal vents, and can withstand up to 176 degrees Fahrenheit. Earlier research had pegged the Pompeii worm's comfort zone as high as 140 F (60 C), far beyond that of other animals. It sounds pretty inhospitable, and to humans it would be, but these strange volcanoes are home to billions of small worms. The worm wears a fleece like covering over its back (which is actually colonies of bacteria) as insulation from the heat and the cold. … They provide a stable, chemical-rich environment for the chemosynthetic bacteria, which in turn serve as food for the worms. Home- The Pompeii worm makes paper-like tube colonies attached to hydrothermal vent chimneys. It is also much flatter, only rising 10m above the ocean floor. Some tubeworms are remarkably long-lived. The first ramped up from 86 to 108 degrees F (30 to 42 C) and the second from 122 to 131 F (50 to 55 C). They set sail aboard the Canadian icebreaker CCGS Sir Wilfrid Laurier (SWL). A bit like you and I, who can stick our finger under a tap with very hot water, but only for a few seconds. An entire ecosystem clings to the chimneylike columns, with worms and many other species consuming each other and the mineral-laden hydrothermal fluids. The Pompeii worm, Alvinella pompejana, is a species of deep-sea polychaete worm (commonly referred to as "bristle worms"). The first wave of interesting discoveries began in November … And then, of course, there's the mud, which spills out onto the cold floor of the Arctic Ocean. The characteristics of Thermophilic bacteria are as follows: They can survive at extremely high temperature, such as 41ºC to 122ºC. They can cope with a wide range of temperatures. The Beaufort Sea tubeworms are only 7-8cm long. The organisms that live around the underwater volcanic vents are completely independent of the sun. They cannot store methane, and have to use it there and then. On 24 August 79 AD, Mount Vesuvius erupted explosively, burying Pompeii under a crust of volcanic ash. Original article on LiveScience.com. They are mud volcanoes, and as the name suggests they are spewing out warm mud – as well as methane gas. But genetic and protein studies showed the worm's tissues would unravel at such high temperatures, just like raw eggs change when cooked. Live Science is part of Future US Inc, an international media group and leading digital publisher. The majority of eggs survive … But having such a slow growth rate would make them slow to colonise the mud flows, explaining why the new mud flows are uninhabited. Visit our corporate site. First on the list is methane, otherwise known as natural gas. Crabs’ teeth are located in their stomachs. 8. The circumstances of its destruction preserved Pompeii’s remains as a unique document of Greco-Roman life. They are commonly found in geothermal high temperature on Earth. "The volcanoes are so large that you can only see a small part of them at any one time," says Charlie Paull of the Monterey Bay Aquarium Research Institute in Moss Landing, California, US. "It means 'welcome,' you see it on the floor in front of houses as a welcome mat [in Pompeii]," Tuck said. The hydrothermal vents upon which Pompeii worms live release jets of "super-heated" (up to 300º C / 570º F) water rich in sulfur and metals compounds. Every year, Håkon Mosby emits several hundred tons of methane. University of Delaware research helped show that the Pompeii worm can survive at scalding temperatures around hydrothermal vents. "Our study concludes that 50 degrees Celsius cannot be tolerated permanently by Alvinella," Shillito told LiveScience in an email interview. Stay up to date on the coronavirus outbreak by signing up to our newsletter today. The worms live in hydrothermal vents. These are formed when a vent in the Earth's surface releases gases. What unusual ability does the dumbo octopus have that helps it conserve energy? Worms. The scientists aren't sure whether it's the methane gas itself that the worms feed on, or hydrogen sulfide, which is made when the nearby microbes oxidise methane. These tube worms, over three feet tall, live off the "smoke" particles from the vent. At the bottom of the Arctic Ocean, in cold dark waters miles away from anywhere, lie five active volcanoes. Ejecting molten rock and gases at 1.5 million tons per second, it’s to imagine how anyone could escape the clutches of Mount Vesuvius. A study published in 2000 estimated that there are between 1000 and 100,000 mud volcanoes in the deep sea – plus all the ones on land. Mud flows from the seafloor and forms a cone-shaped mound around the vent. They discovered large circular structures between 250 and 750m below the surface. One of the most impressive species of life on our planet, Pompeii worms survive at the very bottom of the Pacific Ocean, a place where few other organisms can survive. It is not fully understood how the worms live in the conditions that they do. Salticidae is the largest family of spiders, with over 5,000 species described worldwide. Since their internal temperature has yet to be measured, a Pompeii worm may survive exposure to hot water by dissipating heat through its head to keep its internal temperature within the realm previously known to be compatible with animal survival. To get this, they programmed an autonomous underwater vehicle (AUV) shaped like a torpedo to fly down to 50m above the seabed. In 2000, researchers found tubeworms that took 170-250 years to grow 2m long, The thickets, which Paull describes as "as dense as grass in a hayfield", contained millions of worms. [Life at the Hydrothermal Seep (Video)]. What are the extremes of the deep ocean? They can reach up to 5 inches in length and are pale gray with red tentacle-like gills on their heads. The sea becomes filled with wiggling worms for miles. Yet despite this, mud volcanoes like Håkon Mosby and the Beaufort Sea volcanoes remain mysterious. The Pompeii worms are a species of polychaete worms found in the Pacific Ocean (deep-sea) at hydrothermal vents. The Portuguese Man of War, Physalia, has a sail and is blown by the wind. The Pompeii worm pokes its head out of its tube home to feed and breathe in the cooler water. Animals that can survive the hottest conditions on Earth! ", The world's mud volcanoes are estimated to release 27 million tonnes of methane every year. Exploring the deep-sea vents helps scientists determine the upper temperature limits for life. How is the worm able to tolerate such a range of temperatures? Often one end of a tubeworm can experience near-freezing temperatures, while the other end is exposed to hot fluids flowing out of the seafloor. Physicists recorded the flowing sound of a 'perfect' fluid for the first time, Sprawling 8-mile-long 'canvas' of ice age beasts discovered hidden in Amazon rainforest, Drone catches Arecibo Observatory's last moments, World's largest atom smasher could seed microscopic black holes, Black holes may not exist, but fuzzballs might, wild theory suggests, Biblical Goliath may not have been a giant, Lost islands beneath the North Sea survived a mega-tsunami 8,000 years ago. We are only just scratching the surface of these underwater volcanoes. Register to get answer. Similar chambers could exist below the Beaufort Sea volcanoes. The team then tested heat extremes on the worms, looking at survival and how much stress the different temperatures caused. Creatures » Cellular Organisms » Eukaryotes » Opisthokonts » Animals » Bilateria » Protostomes » Spiralians » Segmented Worms » Sedentaria » Terebelliformia « Pompeii Worms Alvinellidae They can resist temperatures up to 176 degrees Fahrenheit. The water seems to be a mixture of seawater, water from snow and rain, and water from deeply-buried clay. This species lives by clinging around the ‘smokers’ of the hydrothermal vents of the Pacific Oceans mountain ranges, created from the chemicals kicked out at 300 degrees centigrade from the vents that meet cold seawater. Still, the frequent eruptions warm the seas, and water temperatures as high as 9.1 °C were recorded around the flat tops of the volcanoes. Alvinella pompejana, the “Pompeii worm” lives on active hydrothermal edifices at deep-sea vents of the East Pacific Rise.The physical and chemical patterns of its microhabitat were determined from temperature probe measurements, temperature time series, and on-board and shore-based chemical analyses based on discrete sampling (pH, H 2 S, CO 2, CH 4, S 2 O 2-3, Ca, Mg, Cu, Cd, Zn). The methane is a greenhouse gas, but most of it never makes it to the atmosphere, as microbes and tubeworms break it down. While the very hottest water shoots out the top of the chimneys, these structures are so porous that hot water also seeps out the chimney sides and through the worm's tube home. Daily Life in Pompeii. Pompeii Worm (Alvinella Pompejana). The eruptions contain many different chemicals. Every page goes through several hundred of perfecting techniques; in live mode. Their enzymes don’t denature at high temperature and stabilize at high temperature. They can cope with a … 18. The expedition was one of the first of its kind to take place in the Arctic Ocean. The size of these colonies ranged from 10cm across, with only a few dozen worms, to extensive thickets of worms filling most of the ROV camera's field of view. Compared to normal volcanoes, mud volcanoes are much cooler. Both groups of worms survive without light, under intense pressures and in water that is often laced with acid and toxic gases. You may think it would be a disadvantage for a slow-growing tubeworm to live in a dynamic environment such as a mud volcano, as it might not have time to breed before being buried by boiling mud. In fact, mud volcanoes like this may be remarkably common. Learn more about Pompeii… Read about our approach to external linking. A Pompeii worm may survive exposure to hot water by dissipating heat through its head to keep its internal temperature within a suitable range for survival. 20. The "fleece" is actually bacteria. "They erupt frequently and release gas and mud, which bubbles out onto the seafloor. "The tubeworms are using either methane or hydrogen sulfide as an energy source," says Paull. It covers an area of about 2 sq km and belches out mud, water and methane from its centre. More r ecently, Cary et al. So was defined the new phase of excavation to bring the city submerged by Vesuvius back to light. We do not yet know how quickly the Beaufort mud volcano worms grow. Can survive: Extreme heat, variance in temperature. What is the star fish diet? If that is true, the worms are "farming" the bacteria within their guts. The temperature results match up with experiments on related hydrothermal worm species taken from other deep-sea vents, said Ray Lee, a marine biologist at Washington State University who was not involved in the study. However, Lee said there could be other, as yet unknown factors that help Pompeii worms survive hotter temperatures in their deep-sea home. 21. The Great Pompeii Project is the plan to secure the front of the Regio V of the Archaeological Park of Pompeii and from 2017 continues to give great surprises, many more than archaeologists expected.. For this, they used a remotely-operated vehicle (ROV) that beamed back a live high-definition video of the sea floor. © Scientists have discovered that the bacteria insulate the worms from the extreme heat of the vents, and the worms secrete mucus from glands on … Pompeii worms get their name from the Roman city of Pompeii that was destroyed during an eruption of Mount Vesuvius in AD 79. So researchers from the university built a special pressure chamber for the worms to travel to the surface, to recreate the intense pressures at deep ocean vents. They could be used to preserve Organs until ready for transplant. Vent chimneys are very porous, so heat can easily escape from the sides into the papery colonies of pompeii worms. While it is not yet known precisely how the Pompeii worm survives these hellish vent conditions, scientists suspect the answer lies in the fleece-like bacteria on the worm's back; it may be up to a centimetre thick. These jellyfish have the ability to revert back … The handling and chemistry changes during the trip to … Hot pink tube worms living on scalding deep-sea hydrothermal vents actually like to keep things relatively cool, according to a study published today (May 29) in the journal PLOS ONE. But these are not your typical volcanoes, belching out hot molten lava. Since their internal temperature has yet to be measured, a Pompeii worm may survive exposure to hot water by dissipating heat through its head to keep its internal temperature within the realm previously known to be compatible with animal survival. It may be that this mud volcano is so active, and the mud flows on it so young, that the worms haven't yet been able to colonise it. A chain of volcanoes oozing out hot mud may not sound like a nice place to live, but for one group of worms it is paradise. It showed that most of the mud volcanoes had remarkably flat tops surrounded by a circular ridge. Seahorses utter muscular sounds at the time of mating. (University of Delaware College of Marine Studies) 4. The secret lies in a fuzzy hairs along the Pompeii worm's body. The word "have" is Oscan, a dialect that was spoken in Pompeii both before and after the Romans took over the city in 80 B.C. You will receive a verification email shortly. The tube worms seem to prefer some areas of the volcanoes over others, "The tubeworms probably aren't performing the reaction themselves," says Paull. Since their internal temperature has yet to be measured, a Pompeii worm may survive exposure to hot water by dissipating heat through its head to keep its internal temperature within the realm previously known to be compatible with animal survival. "The pressure causes the clay structure to change, which results in a release of water from the clay.". How do Thermophilic bacteria survive? More r ecently, Cary et al. This same water would certainly kill us if we had a bath," Shillito said. The story begins in 2009. 1 Answers. Giant tube worms are marine invertebrates that belong to the family of polychaete annelid worms. The worms perform a chemical reaction, either on methane or hydrogen sulphide, and this releases electrons – which supply energy. Follow us @livescience, Facebook & Google+. The Second Life of Pompeii. they could be inserted into plants to help them survive the winter. Their enzymes work best at high temperature. On one certain night, all the worms simutaneously amputate their back ends which contain eggs and … The Pompeii worm is one of the most heat-tolerant animals on Earth. When mud volcanoes erupt near gas hydrates, the methane in the hydrates can escape, along with methane from deep underground. The tubeworms may simply be growing very slowly. Was it possible that people managed to survive the infamous 79 AD eruption? And they could be put into ice cream to prevent ice crystals from forming . It is an extremophile found … Did anyone survive in Pompeii? Polynesians gather as much as they can and concider them a tasty delicacy. Back in 79 A.D., the citizens of Pompeii were met with a loud burst of smoke on top of the nearby mountaintop. This is different from the Oligochaeta, which are similar in form, but only have a few bristles. Though the tests mean Pompeii worms like their homes a little cooler than thought, the creatures are still one of the most heat-tolerant animals on the planet. "I think it's likely that bacteria living inside the tubeworms are doing all the work. Pompeii worms simultaneously keep their heads (including the gills) in much cooler water while their tails are exposed to hot water. 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. Scientists took seismic measurements of Håkon Mosby from 2008 to 2010, and found no clear evidence that tremors triggered eruptions. This animal is 2 inches (5 cm) long. All of the experiments took place inside a high-pressure aquarium aboard a research ship. Mud volcanoes like Håkon Mosby and the Beaufort Sea volcanoes remain mysterious. It seems the volcanic activity acts as a beacon, attracting life to the area. The scientists discovered that the Pompeii worms survived the lower temperatures with no apparent tissue damage and little heat stress. The ROV's cameras revealed vast thickets of worms. Pompeii worms simultaneously keep their heads (including the gills) in much cooler water while their tails are exposed to hot water. The fleshy pink Pompeii worm (Alvinella pompejana) is one of the most extreme of the deep-sea creatures, perching its long, bristly tubes right next to the shimmering vent fluids. They can survive without water for up to ten years, can survive radiation, and thrive in temperatures as frigid as -272 degrees Centigrade (-457 Fahrenheit) and as thermal as 150 degrees Centigrade (302 Fahrenheit). "The gas coming out of the volcanoes is biogenic methane, which means that it is produced by the decomposition of organic matter and bacteria, and not from oil deposits trapped underground," says Paull. "The hottest animal on the planet, but the most difficult to study, summarizes the Alvinella enigma," said Bruce Shillito, a marine biologist at the University Pierre and Marie Curie in France. The whole setup is eerily similar to another mud volcano, on the other side of the world. The worms are covered by a layer of bacteria. However, there were no worms around the newer mud flows, even though they are richest in methane. Pompeii worms, Alvinella pompejana, live in tubes along hydrothermal vents on the sea floor. These unusual creatures were discovered in 1977. The hydrothermal worms, from the East Pacific Rise,were given two heat tests. not propose that Pompeii worms can live and prosper at such temperatures, but that they can withstand brief exposures to extreme heat. First discovered in the 1980s near the birthplace of evolutionary theory, the Galapagos Islands, Pompeii worms have only ever been found … The worm lives inside a papery tube that it has burrowed into the side of the vent. Shillito and his colleagues now plan to examine the worm's tissues and genes to understand how the animals thrive at the edge of hydrothermal vents. We do not even understand why they are so active. The handling and chemistry changes during the trip to the surface could also affect how the worms respond to the tests, he said. How has the Pompeii worm adapted? There was a problem. Hydrogen sulfide has the advantage that the worms can turn it into sulfur, which they can store much like our bodies store fat.
