A Cameroonian hunter holding a fire-roasted frog (left) and a spear (right) used specifically to hunt this frog species. When in danger, this and several other African frogs have a bizarre defense — claws hidden entirely within the toe can burst through the skin. This frog was captured during a nighttime hunt and was killed by this local hunter by a machete wound to the head. The spear is a heavy wooden pole with three roughly 3-inch nails jutting from the end. Credit: David C. Blackburn
