The Rio Cauca caecilian is a fully aquatic legless amphibian from South America. It has a long body without limbs, which allows it to swim easily in rivers and streams.
Unlike terrestrial caecilians, this one lives only in water and gives birth to live young. It helps maintain balance in rivers by eating small animals.
Immature form that undergoes metamorphosis before adulthood.
