Caecilian

These burrowing creatures look remarkably like earthworms, but are actually amphibians like frogs, toads and salamanders. Rare and reclusive, we still have much to learn about their lifestyles. It wasn’t until recently that we discovered how at least one species rears its young; wrapped around her babies in an underground nest, the mother continuously grows extra layers of skin that her sharp-toothed babies strip off and eat every three days.
