“ | And here let me say that if I have given the impression that the Akka are simply magnified frogs, I regret it. Frog-like they are, and hence my phrase for them—but as unlike the frog, as we know it, as man is unlike the chimpanzee. Springing, I hazard, from the stegocephalia, the ancestor of the frogs, these batrachians followed a different line of evolution and acquired the upright position just as man did his from the four-footed folk. |

The Akka, or Frog-men, are a sapient species of bipedal frog-like vertebrates which inhabit the subterranean realm of Muria. Speculated to descend from labyrinthodonts or primitive stegocephalians, their ancestors were brought to Muria by the Taithu, who recognized the Akka's sapience and helped them develop their civilization.
Biology[]

The Akka are superficially frog-like bipeds, albeit with scaly skin and spikes. Females stand about 6 ft tall (~ 1.82 m), while the males tower over even taller-than-average humans. Their eyes are proportionally huge, round and blue with green irises, and their bodies are colored in orange and white bands.
Unlike actual frogs, the Akka have sharp teeth and well-developed foreheads protected by a horny helmet-like carapace. Their hands sport five webbed fingers tipped with long yellow claws. They have a pouch on their throats which produces vocalizations and don't speak the same language as the humans of Muria.
The Akka are monogamous and viviparous. Reproduction takes place only once every five years and they never give birth to more than two offspring at a time.
