Top-10 new species embrace massive tree, tiny microbes
Print Edition
A cross between a sleek cat and a wide-eyed teddy bear that lives in Andean cloud forests and an eyeless snail that lives in darkness 900-plus meters below ground in Croatia rank among the top-10 new species discovered last year, scientists announced yesterday.
The list, assembled annually since 2008, is intended to attract attention to the fact that researchers continue to discover new species. Nearly 18,000 were identified in 2013, adding to the 2 million known to science.
An international committee of taxonomists and other experts, assembled by the State University of New York College of Environmental Science and Forestry, selects the top 10. The list is released in time for the birthday today of Carolus Linnaeus (1707-1778), the Swedish botanist considered the founder of modern taxonomy.
Scientists believe nature holds another 10 million undiscovered species, from single-celled organisms to mammals, and worry that thousands are becoming extinct faster than they are being identified, said entomologist Quentin Wheeler, president of the environmental science college, part of the SUNY.
“The top 10 is designed to bring attention to the unsung heroes addressing the biodiversity crisis by working to complete an inventory of earth’s plants, animals and microbes,” Wheeler said in a statement.
One top-10, for instance, is the olinguito, the cat-bear amalgam from the cloud forests of Colombia and Ecuador. The 2-kilogram raccoon relative is the first carnivorous mammal discovered in the Western Hemisphere in 35 years.
Scientists had long missed an even bigger quarry such as the 12-meter dragon tree of Thailand, which has soft, sword-shaped leaves and cream-colored flowers with orange filaments.
No one knew about some other top-10s. A submersible exploring beneath Antarctica’s Ross Ice Shelf discovered a yellow 2.5-centimeter sea anemone that burrows into the ice and dangles two dozen tentacles in the frigid water.
“We are very far from having exhausted the knowledge of the biodiversity on Earth,” said zoologist Antonio Valdecasas of the National Museum of Natural Sciences in Madrid and chair of the top-10 committee.
