A mother's duty: Guarding the eggs.

The female King Cobra builds a large nest with dry leaves and twigs. She then lays 20 to 40 eggs inside. Unlike other snakes, she doesn't just leave. She guards the nest for weeks. The decaying leaves create natural heat, which helps the eggs hatch faster. Just before the babies emerge, she leaves, as they are venomous and self-sufficient from birth.
