The yeti crab was discovered in 2005 when a team of researchers from the Monterey Bay Aquarium Research Institute and Institut français de recherche pour l’exploitation de la mer journeyed to the bottom of the South Pacific Ocean with the submarine DSV Alvin. Lipid and isotope analyses provide evidence that epibiotic bacteria are the crab's main food source and K. puravida n. sp. A second species was discovered in 2006, and four more have followed since, until the fifth in 2013. January 16, 2020 – Little red jellies are commonplace near the deep seafloor in Monterey Bay. crab, after the legendary shaggy ?snowman? (Photo courtesy of Michel Segonzac, IFREMER) The rising lava heats water within these fractured subsurface rocks, which eventually seeps or gushes out of the seafloor, carrying minerals that are rich in sulfur and metals. The yeti crab was discovered in March 2005 by a group organized by Robert Vrijenhoek of the Monterey Bay Aquarium Research Institute in Monterey, California and Michel Segonzac of the Ifremer and a Census of Marine Life scientist using the submarine DSV Alvin, operating from RV Atlantis. "The Hoff" is the newest type of yeti crab to be discovered along the Southern Ocean floor near Antarctica. The Yeti Crab. Its discoverers dubbed it the "yeti lobster" or "yeti crab". This map shows the locations of hydrothermal vents along the Pacific-Antarctic ridge that scientists explored during the Easter Microplate expedition. They found that the crab was not only a new species (which they named Kiwa hirsuta), but an entirely new family (Kiwaidae). The yeti crab (Kiwa hirsuta), an unusual, hairy crab with no eyes, was discovered in 2005 on a hydrothermal vent near Easter Island. Most of the crabs were living at depths of about 2,200 meters (7,200 feet) on recent lava flows and areas where warm water was seeping out of the sea floor. It is very difficult to breathe, let alone find food. The "hairy" pincers contain filamentous bacteria, which the creature may use to detoxify poisonous minerals from the water emitted by the hydrothermal vents where it lives. This drawing shows the Yeti crab that was collected by scientists on the Pacific-Antarctic ridge. Subsequently, question is, how far down do yeti crabs live? (Related picture: "'Yeti Crab' Discovered in Deep Pacific.") Yeti crabs heaped in piles, predatory sea stars stalking the perimeter, and ghostlike octopuses are among the extraordinary species discovered clustered … Jun 24, 2015. During one Alvin dive, marine biologist Michel Segonzac, from Institut français de recherche pour l’exploitation de la mer (IFREMER) in France, noticed an unusually large (15-cm-long) crab with hairy arms lurking on the seafloor. The human-occupied submersible Alvin is launched from a special crane on the transom of the research vessel Atlantis. Image: (c) 2005 Mark Spears. A new species of yeti crab piles around the hydrothermal vents in Antarctica. All but one of the yeti crab species are found on one of the most extreme habitats on earth, deep-sea hydrothermal vents, which release boiling-hot … Learn more about the Census of Marine Life and see other species found during this 10-year project. Quite unfortunately, the truly astounding Yeti Crab appears to only inhabit a highly specific and rather restricted habitat range. 7700 Sandholdt Road, Moss Landing, California, 95039 U.S.A. | Phone: 831-775-1700 |, Institut français de recherche pour l’exploitation de la mer, Consejo Superior de Investigaciones Científicas, Mysterious little red jellies: A case of mistaken identity, Five new species of sea slugs found in the ocean depths. Now scientists are finding that their evolution and relationships to one another are probably incorrect. Research article: The drawing was created by scientific illustrator Karen Jacobson, who worked with the scientists on board the research ship Atlantis. This crab was first observed in March 2005 by marine biologists using the research submarine Alvin to explore hydrothermal vents along the Pacific-Antarctic ridge, south of Easter Island. Moreover, when was the Yeti Crab Discovered? The vents may be a safe haven for crabs, which typically can't tolerate cold waters. Exactly how the Yeti crabs fit into hydrothermal-vent ecosystems is still a mystery. Discovery of the Yeti Crabs These crabs were observed for first time in March 2005, by the marine researchers in the submarine Alvin, who were exploring hydrothermal vents along the Pacific Antarctic ridge, in the south of Easter Island. Image: (c) 2005 Karen Jacobsen ISSI. [7] Alternatively, it may feed on bacteria, although it is generally thought to be a carnivore. The vent sites are indicated by black dots with labels indicating their latitudes. An international team of scientists recently announced the discovery of a new species of blind deep-sea crab whose legs are covered with long, pale yellow hairs. Segonzac asked the Alvin pilots to collect this crab and bring it back to the surface. The second species were discovered in 2006, and four more have followed since and until the fifth in the year 2013. Their white coloring and strange hair patterns are thought to be adaptations to these extreme environments. Research programs at the Monterey Bay Aquarium Research Institute (MBARI) encompass the entire ocean, from the surface waters to the deep seafloor, and from the coastal zone to the open sea. [1] Based on both morphology and molecular data, the organism was deemed to form a new biological family (Kiwaidae);[4] a second species, Kiwa puravida, was discovered in 2006 and described in 2011. June 5, 2018 – In honor of World Oceans Day, MBARI researchers highlight the discovery of over 200 deep-sea animal species over the last 30 years. Hydrothermal vents often form near mid-ocean ridges, where hot lava rises up beneath the seafloor, causing the Earth’s crust to split apart. The crabs were found in piles around hydrothermal vents on the seafloor during a 2010 expedition conducted by British scientists. [5] Yeti Crabs live in the deep oceans, in hydrothermal vents, which are deep within the ocean. The Yeti crab, Kiwa hirsuta Macpherson et al., is the single known species in a recently discovered crab family Kiwaidae (Decapoda: Galatheoidea) from deep-sea hydrothermal vents. First species of yeti crab found in Antarctica named after British deep-sea biologist. Vrijenhoek and his team were addressing this question by comparing the DNA of animals at hydrothermal vents in different parts of the Pacific Ocean. Identification: The Yeti Crab. This animal now resides in a sample jar at the French National History Museum in Paris, as part of its large reference collection of deep-sea crabs. The expedition was led by Monetary Bay Aqaurium Reasearch Institute (MBARI) scientist Bob Vrijenhoek. The ε- and γ- proteobacteria that this methane-seep species farms are closely related to hydrothermal-vent decapod epibionts. This decapod, which is approximately 15 cm (5.9 in) long, is notable for the quantity of silky blond setae (resembling fur) covering its pereiopods (thoracic legs, including claws). Yeti Crab Distribution, Habitat, and Ecology. The need to understand the ocean in all its complexity and variability drives MBARI's research and development efforts. The term "furry lobster" is more commonly used for the family Synaxidae.[8]. The kiwa hirstu use their blonde setae to gorw bacteria for chemosynthetesis, "A new squat lobster family of Galatheoidea (Crustacea, Decapoda, Anomura) from the hydrothermal vents of the Pacific–Antarctic Ridge", "Easter Microplate Expedition March 12–April 6, 2005", "Dancing for food in the deep sea: bacterial farming by a new species of yeti crab", "Dancing for Food in the Deep Sea: Bacterial Farming by a New Species of Yeti Crab", "The biogeography of the yeti crabs (Kiwaidae) with notes on the phylogeny of the Chirostyloidea (Decapoda: Anomura)", https://en.wikipedia.org/w/index.php?title=Kiwa_hirsuta&oldid=1001580680, Creative Commons Attribution-ShareAlike License, This page was last edited on 20 January 2021, at 09:28. But on inspection, they've usually been attributed to other wildlife, such as bears, antelopes and monkeys. [2], K. hirsuta was discovered in March 2005 by a group organized by Robert Vrijenhoek of the Monterey Bay Aquarium Research Institute in Monterey, California and Michel Segonzac of the Ifremer and a Census of Marine Life scientist using the submarine DSV Alvin, operating from RV Atlantis. Zoosystema, 27:4 (2005). These vents provide hot water which makes up the environment of where these crabs live.The crabs regulate their ecosystem by using their hairy arms to collect toxins released from the hydrothermal vents. This process is known as chemosynthesis. The R/V Atlantis is operated by Woods Hole Oceanographic Institution and is used by scientists from around the world. Image: (c) 2005 Ifremer / A. Fifis. Its discoverers dubbed it the "yeti lobster" or "yeti crab". THE DISCOVERY In March, 2005, the research submarine Alvin was used to explore hydrothermal vents along the Pacific-Antartic ridge, which is south of Easter Island. of the Himalayas. Jones and his coauthors saw the crabs eating mussels that were cracked open when Alvin landed on the seafloor. Less formally, the newfound creature has become known as the ?Yeti? Amazingly, a variety of deep-sea animals have found ways to incorporate the sulfur-loving bacteria within their bodies, so that they too can obtain nutrition from the chemicals flowing up out of the seafloor. Kiwa hirsuta is a crustacean discovered in 2005 in the South Pacific Ocean. Their hairy arms make them look like the mythical abominable snowman. Most of the crabs were living at depths of about 2,200 meters (7,200 feet) on recent lava flows and areas where warm water was seeping out of the sea floor. In 2006, a species of yeti crab called Kiwa puravida was found around a cold seep in deep water near Costa Rica.It also has hairy legs. Macpherson et al. The yeti crab — so-called because of the hair-like bristles that cover its arms — is only the second of its family to be discovered. The yeti crab (Kiwa hirsuta), an unusual, hairy crab with no eyes, was discovered in 2005 on a hydrothermal vent near Easter Island.It represents not only a new species but also a new genus—Kiwa, after the mythological Polynesian goddess of shellfish.Learn more about the Census of Marine Life and see other species found during this 10-year project. 2005 on . Scientists have officially described four species of yeti crabs, the first of which was found in 2005, and all of which sport furry claws. The name of the new family of deep-sea crab discovered in March 2005 is Kiwaidae, which comes from Kiwa, a Polynesian goddess of crustaceans. London: The first species of Yeti crab from hydrothermal vent systems in Antarctica, has been discovered by a team of British scientists. named the genus Kiwa after "the goddess of the shellfish in the Polynesian mythology", although "Kiwa" is a male guardian of the sea in Māori mythology. According MBARI biologist Joe Jones, Many of the crabs were hiding underneath or behind rocksall we could see were the tips of their arms sticking out. Feb 12, 2018. The researchers saw more of these unusual crabs during subsequent Alvin dives. [2], Although it is often referred to as the "furry lobster" outside the scientific literature,[2] Kiwa hirsuta is a squat lobster,[1] more closely related to crabs and hermit crabs than true lobsters. The yeti crab was first discovered by the group of scientists in the year 2005. Ever since deep-sea hydrothermal vents were first discovered in the late 1970s, marine biologists have been fascinated by the unique animals that live in these areas. [1] This decapod, which is approximately 15 cm (5.9 in) long, is notable for the quantity of silky blond setae (resembling fur) covering its pereiopods (thoracic legs, including claws). This decapod, which is approximately 15 cm (5.9 in) long, is notable for the quantity of silky blond setae (resembling fur) covering its pereiopods (thoracic legs, including claws). It was an off Easter Island in the hydrothermal vents along the Pacific-Antarctica Ridge on the ocean floor. Named after world-renowned British deep-sea and polar biologist professor Paul Tyler, the species Kiwa Tyleri belongs to an enigmatic group of squat lobsters known as Kiwaidae. The researchers saw more of these unusual crabs during subsequent Alvin dives. The first species of Yeti Crab from hydrothermal vent systems of the East Scotia Ridge in the Southern Ocean, Antarctica, has been described by a team of British scientists. December 12, 2018 – Marine biologists recently discovered five new species of colorful nudibranchs on the deep seafloor offshore of California and Baja California. Yeti crabs are found in several locations in ocean trenches, with 4 species on the Pacific Antarctic Ridge, on the Pacific continental slope off Costa Rica, on the SW Indian Ridge, at the Dragon hydrothermal vent and in the far South Atlantic, on the East Scotia Ridge. Deep-sea fish use hydrothermal vents to incubate eggs. Meanwhile, crab expert Joe Jones is just hoping for another chance to go back and see what else is lurking around the hydrothermal vents of the Pacific-Atlantic Ridge. Discovered in 2010, the yeti crab (Kiwa hirsuta) lives in thermal vents near Antarctica that reach temperatures of up to 720 °F (380 °C). The researchers saw more of these unusual crabs during subsequent Alvin dives. Putative Yeti skulls have been found, as well as bone fragments and hair samples. It's only the third known species of yeti crab, a group of shaggy-armed creatures first discovered in the South Pacific in 2005. Yeti Crabs, Ghost Octopi Found at 1st Antarctic Deep-Sea Vents Share 1 The white-eared opossum has a longevity quotient of 0.3, making it unusually short-lived for its size. This crab must live only near the hydrothermal vents which provide it warmth, as otherwise, the crab … According MBARI biologist Joe Jones, “Many of the crabs were hiding underneath or behind rocks—all we could see were the tips of their arms sticking out.”. has highly-modified setae (hairs) on its 3rd maxilliped (a mouth appendage) which it uses to harvest these bacteria. 831-775-1835, kfb@mbari.org. The Yeti crab was discovered during the Easter Microplate expedition to the southeast Pacific, led by MBARI scientist Bob Vrijenhoek. Because of its hairy legs, this animal was nicknamed the “Yeti crab,” after the fabled Yeti, the abominable snowman of the Himalayas. Most of the crabs were living at depths of about 2,200 meters (7,200 feet) on recent lava flows and areas where warm water was seeping out of the sea floor. The Yeti Crab is a crustacean discovered in 2005 in the South Pacific Ocean. Specialized bacteria live off of these hot, metal-rich hydrothermal fluids. This is not as far-fetched as it sounds—at least two other crab species have similar habits. Alternatively, lacking eyes, the crabs may use their hairs (which are actually flexible, hair-like spines called setae) as tiny chemical and physical sensors that help them find food or mates in the deep sea. The thermal vents, while ridiculously hot inside, are surrounded by freezing waters. The feathery hairs or “setae” on the Yeti crab’s arms are covered by dense colonies of filamentous bacteria. Web link, For additional information or images relating to this article, please contact: Kim Fulton-Bennett It was found along the Pacific-Antarctic Ridge, 1,500 kilometres (930 mi) south of Easter Island at a depth of 2,200 metres (7,200 ft), living on hydrothermal vents. In 2010, a third species of Kiwa was discovered near the coast of Antarctica around a hydrothermal vent.This species has hairs on its undersurface and has been named Kiwa tyleri, or the Hoff crab. In fact, to date, the only known populations of this impressive animal occur along the Pacific-Antarctic Ridge, south of Easter Island. It was off Easter Island in the hydrothermal vents along the Pacific-Antarctic Ridge on the ocean floor. A nonprofit oceanographic research center. After returning to shore, researchers Segonzac and Jones worked with Enrique Macpherson from the Consejo Superior de Investigaciones Científicas (CSIC) in Spain to identify the crab they had collected. The Yeti Crab Discovered in 2005 in the South Pacific, the yeti crab (or kiwa hirsuita) lives 7,000 feet deep, somehow thriving and flourishing in ocean thermal vents that can heat up … The modern Yeti Crabs are well adapted to the toxic waters of hydrothermal vents and cold seeps (think of undersea volcanoes). Here, toxic sulfurous hydrocarbons poison most animals and reduce dissolved oxygen. It represents not only a new species but also a new genus—Kiwa, after the mythological Polynesian goddess of shellfish. But they also saw Yeti crabs holding their hairy claws out over plumes of warm water from hydrothermal vents. [3] The discovery was announced on 7 March 2006. [9] Hirsuta is Latin for "hairy". [6], The animal has strongly reduced eyes that lack pigment, and is thought to be blind. 1.) So far, scientists have only had a first-hand look at the one Yeti crab that was brought up by Alvin. E. Macpherson, Jones, W., and Segonzac, M. A new squat lobster family of Galatheoidea (Crustacea, Decapoda, Anomura) from the hydrothermal vents of the Pacific-Antarctic Ridge. This unimaginable environment is home to "yeti crabs", clawed crustaceans first discovered in 2005. The Yeti crab is a distant relative to the hermit crabs commonly seen lurking in tide pools. Scientists speculate that the Yeti crab might cultivate and eat these bacteria. Kiwa hirsuta is a crustacean discovered in 2005 in the South Pacific Ocean. The yeti crab was only first discovered by a group of scientists in 2005. Image: (c) 2005 MBARI. Because the crab’s arm hairs support large colonies of filamentous bacteria, the scientists speculated that the crabs might be “farming” the bacteria, perhaps as a source of food. The primary goal of this expedition was to learn how bottom-dwelling animals from one deep-sea hydrothermal vent are able to colonize other hydrothermal vents hundreds or thousands of miles away.
