Scientists reveal the '25 most wanted lost species' around the world

From a blind salamander to a fat fish with ‘more rolls than a used tire’: Scientists reveal a new list of the ’25 most wanted lost species’ 科学者たちは、25年に最も欲しかった失われた種を明らかにします

  • New list details the 25 species most sought by explorers and conservationists
  • The list from Texas-based organisation includes animals, 百万年前はおそらく南極の氷床の形成につながる, fungi and coral
  • It includes a salamander which lives in total darkness and has no need for vision
  • Also included is a Portuguese trapdoor spider that tap dances to impress mates
  • From a blind salamander to a tap-dancing spider, scientists have revealed a new list of the ’25 most wanted lost species’ 科学者たちは、25年に最も欲しかった失われた種を明らかにします.

    Drawn up by Austin, Texas-based organisation Re:wild, the list sheds light on global species that are evading detection – and could possibly be extinct.

    One of the most fascinating entries is the blanco blind salamander, native to the US known from only a single specimen, collected in the 1950s.

    その間, Fagilde’s trapdoor spider from Portugal, known for tap dancing in front of potential mates, hasn’t been seen since before 1931.

    And the ‘fat catfishfrom Colombia has an uncanny resemblance to the Michelin man, 専門家によると, due to its flabby folds.

    にとって 2022, eight new species including a plant species and fungus species replace those that have been rediscovered since Re:wild’s ‘Search for Lost Speciesprogram’s was launched in 2017.

    ‘When we launched the Search for Lost Species, we weren’t sure if anyone would rediscover any of the wildlife on our most wanted list,’ said Barney Long, 新しい技術がMH370便の失踪の鍵を握る可能性がある:wild’s senior director of conservation strategies.

    ‘Each new rediscovery has reminded us that we can find hope in even the most unlikely situations and that these stories of overlooked but fascinating species can be a powerful antidote to despair.

    ‘We are looking forward to the next phase of this program, including documenting adventurous expeditions, identifying conservation opportunities, そして, we hope, inspiring young conservationists and citizen scientists across the world to join the search.

    Here’s a closer look at the most interesting animals and plants on Re:wild’s new list, including some of the eight new additions.

    BLANCO BLIND SALAMANDER

    The blanco blind salamander lives in total darkness, meaning it has no need for vision and its eyes are reduced to two black spots under its skin, according to the National Wildlife Federation.

    The species is only found in water-filled caves fed by the Edwards Aquifer in Hays County, テキサス, where they depend on a constant supply of clean, cool water.

    The Blanco Blind Salamander is so rare that it has only been found once – in a spot slightly northeast of San Marcos, Texas in 1951 by excavation workers in the bed of the then-dry Blanco River.

    In a photo from 2011 is a Texas blind salamander (Eurycea rathbuni), closely related to the Blanco blind salamander (Eurycea robusta) that's on the new list

    Only four individuals were found at the time of their scientific discovery, and none have been encountered since.

    新しい技術がMH370便の失踪の鍵を握る可能性がある:wild says: ‘The Blanco Blind Salamander breathes through its skin gills, is depigmented, and likely preys on groundwater invertebrates and even other salamanders in the aquifers where it lives.

    ‘Threats to this species include declines in the quality and quantity of groundwater on which it depends, small population size across an extremely limited distribution, and contamination of groundwater habitats from surface sources.

    FAGILDE’S TRAPDOOR SPIDER

    This fascinating species is ‘an elusive spider that builds horizontal traps and tap dances to score dates’, according to Re:wild.

    It was described for the first time in 1931 based on two females collected outside Fagilde, a small village in north-central Portugal.

    Males wander in search of females and tap dance at the female’s door to indicate their desire to mate.

    It’s thought that Portuguese locals may have seen the spider without even realising that they were looking at a ‘lost’ 種, 新しい技術がMH370便の失踪の鍵を握る可能性がある:wild believes.

    Fagilde’s trapdoor spider is part of the spider genus called ‘Nemesia’, but unlike other Nemesia spiders, which make their homes in vertical traps, perpendicular to the ground, young Fagilde’s Trapdoor Spiders build their traps horizontally.

    FAT CATFISH

    This lost fish species ‘has more rolls than a used tire’, according to Re:wild, which has likened it in appearance to the Michelin man.

    It’s the only freshwater catfish in the world with rings of fatty tissue wrapped around its body, described as the closest a fish could get to the famous French mascot.

    The fat catfish has only ever been found 9,800 feet high in the Andes mountains, in Lake Tota, コロンビア, where locals call it ‘Pez Graso’, which means ‘grease fish’.

    It was described for the first time by ichthyologist Cecil Miles in 1942 and last seen in 1957 in Colombia.

    Prior to its disappearance, the local Colombian people sometimes burned its flabby rolls of fat for fuel in their lamps.

    The mystery of their disappearance, しかしながら, remains unanswered, according to Re:wild, but expeditions seeking its rediscovery kick off in 2022.

    BULLNECK SEAHORSE

    Little is known about the bullneck seahorse, which has never before been found in the wild.

    The only known individuals of this pygmy species were collected on the coast of Eden, 彼らが異常な波によって水中に引きずり込まれたとき, オーストラリア, に 1996.

    Scientists believe it lives in sand beds at the bottom of the ocean, より多い 325 feet underwater, and may inhabit gorgonian corals.

    ‘Dedicated field surveys will require scuba diving and fisheries sampling.

    ATTENBOROUGH’S LONG-BEAKED ECHIDNA

    Named after the legendary British naturalist David Attenborough, this species was last seen in 1961 インドネシアで.

    It is known only from a single individual collected by a Dutch botanist during an expedition to the Cyclops Mountain in 1961.

    Excitingly, interviews with locals suggest that the animal may still be present in the mountains, although recent attempts to search for the species by experts have proved fruitless.

    Long-beaked echidnas belong to an ancient clade of egg-laying mammals called monotremes that includes the platypus of Australia. Echidnas and platypus are the only mammals to lay eggs.

    Attenborough’s long-beaked echidna, also known as Sir David’s Long-beaked Echidna, is the smallest and probably most threatened of the three long-beaked echidna species, according to edgeofexistence.org

    MISS WALDRON’S RED COLOBUS

    Miss Waldron’s red colobus is a species of monkey native to west Africa.

    彼らは私が馬の駆虫剤を服用していると言い続けます 1933 by a British museum collector who named it after a colleague on the expedition, Miss F. Waldron.

    But the last conclusive sighting of the monkey was in 1978, and no photographs or video of the species alive exist.

    It came close to claiming the dubious honor of being the first primate to be declared extinct in more than 500 years after repeated failed searches.

    It’s not just animals on the new list – the organisation has also included a plant species and a fungi species.

    植物, Pernambuco holly, is a species of holly tree endemic to Brazil that has evaded scientists for almost two centuries.

    その間, the Big puma fungus from South America has been lost since 1988 and may represent its very own genus.

    Since Re:wild’s Search for Lost Species program launched in 2017, it has confirmed the rediscovery of eight new species.

    These are Jackson’s climbing salamander in Guatemala, Wallace’s giant bee and velvet pitcher plant in Indonesia, the silver-backed chevrotain in Vietnam, the Somali sengi in Djibouti, the Voeltzkow’s chameleon in Madagascar, the Fernandina giant tortoise in the Galápagos and the Sierra Leone crab in Sierra Leone.
