Caecilians are legless amphibians that spend most of their lives underground. Some give birth to live young, whereas others lay eggs. When certain species of caecilians hatch, they eat via maternal dermatophagy-peeling off and consuming their mother's outer layer of skin. The skin is rich in nutrients and causes the larvae to grow rapidly. The mother, meanwhile, isn't injured, and regrows her skin every three days.
