Northern water and garter snakes hold their eggs internally until they hatch, this is called. Females in some animals both lay and guard their eggs. Five-lined skinks protect their eggs by laying them inside rocks, and guard them. Red-backed salamanders lay their eggs inside rotting logs and guard them. Wolf spiders carry their eggs on their back in an egg sac, they hatch on the mother. Nursery web spiders build a nursery web in which they guard their egg sac and hatched young. Giant water bugs do and carry the eggs on their back. like a man should.
