A large tree frog, Nyctimystes, with enormous eyes is pictured in this undated handout photo. The Nyctimystes was found next to a clear running mountain river during a Conservation International (CI) led Rapid Assessment Program (RAP) expedition of Papua New Guinea's highlands wilderness in 2008 and is believed to be new to science. Jumping spiders, a striped gecko and a chirping frog are among more than 50 new species discovered in Papua-New Guinea, the environmental group Conservation International reported on March 24, 2009.[Agencies]
