Caecilia interrupta Cuvier, 1829
Distribution and habitat
Widely distributed east of the Andes: originally discovered in Brazil, reported to exist in Argentina, Bolivia, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, moist savanna, subtropical or tropical moist shrubland, subtropical or tropical seasonally wet or flooded lowland grassland, pastureland, plantations, rural gardens, and heavily degraded former forest.
Nestlings are equipped with 44 spoon-shaped teeth to feed on the outer layer of their mother's skin. Young feed all at once for some seven minutes; then they all rest for three days as the female grows a new outer skin layer. This phenomenon is known as maternal dermatophagy. This practice and morphological similarities are shared with its African relative Boulengerula taitana, suggesting it evolved over 100 million years ago.
