The male of the midwife toad (Alytes obstetricans, top) protects the eggs he fertilized by carrying them between his hindlegs. Females of the marbled snout-burrower (Hemisus marmoratus), also known as the shovel-nosed frog, can build a slide to help tadpoles to the water from an underground breeding chamber.
