They are viviparous animals, giving birth to young that possess external gills. Of the five genera in the family, Atretochoana, Potamotyphlus and Typhlonectes are entirely aquatic, while Chthonerpeton and Nectocaecilia are semiaquatic.[1] Atretochoana reaches 100 cm (39 in) in length, but other species in the family range from 20 to 60 cm (7.9–23.6 in).[1]
