21、that for more than a hundred years,the olinguito had been wrongly identified.This mammal,which looks a lot like a teddy bear,leaps through trees at night.The smallest member of the raccoon family,the olinguito can be found in Ecuador and Colombia.It is the first species of this type to be discovered

22、 in the Americas in thirty-five years.Finding new species of birds is almost as rare as finding new mammals.Finding one in a major city is rarer still.Yet in 2009,researchers discovered the Cambodian tailorbird in and around Phnom Penhincluding in the middle of a road construction site.A detailed se

23、t of tests revealed that this tailorbird was a separate,new species.Besides studying its genes and feathers,scientists studied its pretty song.While all tailorbirds warble,no two species sound quite the same.Sure enough,the song of the Cambodian tailorbird sets it apart from all the rest.Mistaken Id

24、entityHumans may encounter an unidentified species for years while mistaking it for a familiar species.This often happens because the two species look the same,at least on the outside.These are called cryptic species.They are only found to be distinct when scientists study their genetic code.As DNA

25、technology is used more and more,reports of distinct new species are on the rise.Olinguitos have smaller,rounder faces and shorter tails than the olingos,which they were mistaken for.The Cambodian tailorbird is hard to find because it lives in dense brush.Animal Discoveries Level U34Table of Content

42、iscoveries Level U1112Underwater WondersScientists discovered the Gorgons head starfish in 2010,about half a mile(800 m)beneath the surface of the North Atlantic Ocean.The Gorgons head,a species of basket star,has five curly,branching arms that split off from its body.The five arms include as many a

43、s five thousand tips.The tips help this basket star feed on plankton and shrimp floating by in the water.It also uses its arms to walk along the seabed.They even protect the animal when its disturbed by curling around it to form a tight ball.Since Earths oceans are vast,large portions have yet to be

44、 explored.However,thats not the reason it took until 2013 to discover the walking bamboo shark.Like most sharks,the walking bamboo shark is no threat to humans.It lives off the coast of Indonesia.Scientists discovered it because its coloration differs from that of other bamboo sharks.This new specie

45、s is thought to reach about 30 inches(80 cm)in length.It uses its fins to push itself along the ocean floor in search of food.The wiggling movement makes it look as though the shark is walking.Because these sharks are so rare,the government of Indonesia is taking steps to protect them.The Gorgons he

46、ad starfish is named for the Gorgons from Greek mythology.These creatures had hundreds of snakes on their heads instead of hair.The walking bamboo shark has different patterns of spots and bands than other bamboo sharks.Animal Discoveries Level U56Monkey ManiaIn 2007,a new species of monkey was iden

47、tified in the remote forests of the Democratic Republic of the Congo.The lesula has large,expressive eyes.It is described as shy and quiet.The first one found by scientists was being kept as a girls pet.The lesula was the first new species of monkey found in twenty-eight years.Yet in 2010,scientists

48、 found another new monkey by listening to its complex calls.The Caquet titi monkey lives in the Amazon jungle of Colombia,along with about twenty other species of titi monkey.What sets it apart from other titi monkeys is its bushy red beard and the absence of a white bar on its forehead.Another uniq

49、ue feature of this species:Its babies purr like cats.A healthy population of these monkeys should be in the thousands.However,fewer than 250 Caquet titi monkeys are thought to exist today.So the newly discovered titi monkey is already considered endangered.Freaky,Fabulous FrogsNo bigger than a pea,t

50、he Matang narrow-mouthed frog is one of the smallest known frogs in the world.It was discovered on Borneo,an island in Southeast Asia,in 2010.Although examples of these frogs are found in century-old museum collections,scientists simply thought they were juveniles of a different species.They learned
