The Amphibians are a sapient race of bipedal frog-like creatures native to South America. They live in tribal settlements and possess six limbs - two legs and four arms - in addition to a short tail.


  • The Sentōru no Nayami manga series takes place in a universe in which all modern vertebrates evolved from a six-legged ancestral body plan. Besides the Amphibians, other forms which have retained the six limbs include Centaurs, Mermaids (though theirs are modified as fins), "Winged People", "Dragon People", and the extinct "Tigermen". In contrast, races such as the "Horned People", "Long-Ears", Fauns and Antarcticans have lost their central limbs.
