The 2015 Top 10 Species list is compiled annually by the International Institute for Species Exploration or IISE. It calls attention to discoveries that are made even as species are going extinct faster than they are identified. Scientists believe 10 million species await discovery, five times the number that are already known to science. IISE founding director Quentin Wheeler says, “The Top 10 is a reminder of the wonders awaiting us.”
