- ‘The viviparous quadrupeds - literally means four-footed mammals bearing living offspring.’
- ‘These may be viviparous, in which case the mother's body provides nourishment to the embryo, or ovoviviparous, in which case the eggs develop without additional nourishment inside the mother.’
- ‘Depending on environmental conditions, it can shift from viviparous to oviparous reproduction, with production of encysted and dehydrated embryos.’
- ‘If only these creatures had been able to develop a viviparous capability, so that they could give birth to their babies at sea, they would have an assured future.’
- ‘Females are viviparous and give birth to a single litter of up to five offspring.’
(of a plant) reproducing from buds which form plantlets while still attached to the parent plant, or from seeds which germinate within the fruit.‘Evidence of a carotenoid mutant of rice was suggested by the phenotype of several mutants for which viviparous seeds germinated into albino seedlings.’‘Two new viviparous mutants showed some signs of precocious germination but did not emerge fully on the cob.’
Mid 17th century from Latin viviparus (from vivus ‘alive’ + -parus ‘bearing’) + -ous.
