June 24, 2008—Eleven species of African frogs—including Trichobatracus robustus (top) and Astylosternus perreti (bottom)—sport a Wolverine-like defense mechanism, scientists have announced. When threatened, the amphibians pierce their skin with toe bones, sprouting makeshift claws with which to attack predators. David C. Blackburn, a biologist at Harvard University, came across the frogs while conducting fieldwork in Cameroon. When he picked up one of the fist-size amphibians, it kicked its hind legs violently.
