Viviparous means giving birth to live offspring that develop inside the mother's body, and this is what hammerhead sharks and guppies do. Oviparous means laying eggs that hatch outside the mother's body, which doesn't apply to these species. Ovoviviparous means retaining eggs inside the mother's body until they hatch, but the offspring are still nourished by the egg yolk and not the mother, so this isn't the correct term either. Omnviviparous and aviviparous are not recognized scientific terms.
