 The ringed caecilian ( Siphonops annulatus ) has developed a unique adaptation for the purposes of reproduction . The progeny feed on a skin layer that is specially developed by the adult in a phenomenon known as maternal dermatophagy . The brood feed as a batch for about seven minutes at intervals of approximately three days which gives the skin an opportunity to regenerate . Meanwhile , they have been observed to ingest fluid exuded from the maternal cloaca .
