Ailao Mustache Toad (Virbrissaphora ailaonica) -named for the spikes they grow above their mouths. The Ailao mustache toad is one of two species, the other being the Emei mustache toad. During the mating season, the males will grow sharp spikes around the mouth and use them as weapons to fight other males. Their front arms also get beefed up. When the mating season is over, they will shed the spikes. The main difference between the two species is the placement of the spikes on the face.
