কিছু নতুন আবিস্কৃত রেয়ার প্রাণীর ছবি : ০১. এই টিউব নাকওয়ালা বাদুডটি পাপুয়া নিউ গিনিতে ধরা পড়ে ২০০৯ সালে । ০২. Camouflaged in a Muller Range forest on Papua New Guinea, a new leaf katydid species peers pinkly at the camera in 2009. The animal likely eats flowers in the forest's tall trees. ০৩. A feather-tailed opossum clings to a tree branch in Papua New Guinea's Muller Range in September 2009. Though it has yet to be scientifically documented, the elusive species has been reported once before before, on a nearby mountain in 1985. ০৪. Rare Jewel Found in the Muller Range in September 2009, a new, unnamed species of katydid glimmers dark emerald—a color Naskrecki, director of Conservation International's Invertebrate RAP, had never before seen in katydids. Katydids, which are related to crickets and grasshoppers, play an important role in the rain forest's food chain, providing protein to monkeys, bats, birds, rodents, and even other insects. ০৫. Country Mouse This new species of long-tailed mouse resembles tree mice of Papua New Guinea, but don't be fooled: The rodent, found in the Nakanai mountains in 2009, lives on the ground. The researchers came to that conclusion after noticing the mouse's narrow feet and forward-pointing front teeth—useful for digging and moving soil. Its white-tipped tail is unique among all the mice in the area and may suggest the species belongs to an entirely new genus. ০৬. A "Most Exciting" Find Unlike most of its relatives, which chirp at night, this new, 0.8-inch-long (2-centimeter-long) frog species sends out its mating calls right after afternoon storms. The unnamed species was the "most exciting and surprising herpetological discovery" of the Nakanai RAP, herpetologist and RAP team leader Stephen Richards said in a statement—the amphibian belongs to a group of frogs previously documented in only the Solomon Islands, hundreds of miles to the east. ০৭. Major Discovery A huge-headed "major" ant of a thorny new species collects food from smaller workers in Papua New Guineau's Muller Range during a 2009 expedition. The majors use their muscular jaws to crush seeds that the smaller workers bring back to the nest. Like other species in the Pheidole genus, the newfound ants are all divided into workers and majors, and the new species is very opportunistic, RAP director and Conservation International entomologist Leeann Alonso told National Geographic News. "Some ants have a specialized diet," Alonso said. But the new ants "catch live insects, scavenge for dead insects and seeds. ..." The new species was also the first to discover the crumbs researchers had inadvertently dropped near camp. "That's actually one of the best ways to find ants," she said. "Sit down there, drop some food on the ground, and wait for them to come." ০৮. New Species Aims for the Eyes? Unlike most katydids, which use a combination of camouflage and "startle displays," such as flashing their wings, to avoid being eaten, this new species uses its muscular, spike-covered legs to jab attackers into submission. "I got jabbed quite a few times," Naskrecki, the invertebrate expert, told National Geographic News, adding that the new species probably evolved this defense mechanism to ward off birds and bats. "It probably aims for the eyes." ০৯. Tiny New Frog A frog small enough to sit on a thumbnail rests on a leaf in Papua New Guinea's Muller Range in 2009. This species "nearly eluded the RAP team altogether," as the scientists had to search the forest floor in pouring rain to trace the sound of the "soft, scratching, cricket-like" call, according to a Conservation International statement. The frog and all its closest relatives are found only on the island of New Guinea.
