Katherine Krynak, a PhD student at Case Western Reserve University and her husband Tim Krynak, project manager at Cleveland Metroparks Natural Resources Division, discovered the new species, called the Mutable rainfrog (Pristimantis mutabilis), in 2006 at nature preserve Reserva Las Gralarias. The couple nicknamed the amphibian the “punk rocker” frog for its thorn-like spines. It wasn’t until three years later that the couple discovered the species’ secret shape-shifting skills, which may help the marble-size frog be better camouflaged in its mossy surroundings.
