Researchers recently discovered a most unusual parenting method in Boulengerula Taitanus, a blind, worm-like amphibian called a caecilian. It feeds its young by letting them tear off its own skin with hooked white teeth. Scientists say this behavior has never been witnessed in any land-based animal.
Unlike most caecilians, B. Taitanus lays eggs. The skin of the female parent actually becomes thicker and nutrient rich when the eggs are about to hatch, preparing a delicious meal for her cuddly worm-lizard babies. Apparently in live-bearing caecilians, the fetuses feed on the womb-like oviduct of their mothers.

Perhaps most disturbing, researchers suggested that B. Taitanus' parenting behavior may shed light on the evolution of nursing behavior (lactation) in mammals.
