New Borneo FishOne of 17 new species of fish discovered in central Borneo, the 1.5-inch-long (3.6-centimeter-long) eight-banded barb can be found in shady rain forest streams and swamps.More than 120 new species—including the world's longest insect, a "ninja" slug, and a lungless frog—have been found in Borneo since 2007, according to a new report released on Earth Day by the international conservation group WWF. The world's third largest island, Borneo (map) is divided among Malaysia, Indonesia, and Brunei."On average, there are three new species found every month," said ecologist Adam Tomasek, leader of WWF's team for the 54-million-acre (22-million-hectare) Heart of Borneo region. "What's really compelling is the diversity of these species."(See pictures of Borneo forests in National Geographic magazine.)—Carolyn Barry in Sydney
