vi•vip•a•rousvaɪˈvɪp ər əs, vɪ-(adj.)
bringing forth living young rather than eggs.
producing seeds that germinate on the plant.
Origin of viviparous:
1640–50; < L vīviparus. See vivi -, -parous
producing living young (not eggs)
Being born alive, as are most mammals, some reptiles, and a few fish (as opposed to being laid as an egg and subsequently hatching, as do most birds and many other species).
Arising from an embryo that develops from the outset (rather than from a true seed that then germinates).
Origin: From viviparus, from vivus + pario.
producing young in a living state, as most mammals, or as those plants the offspring of which are produced alive, either by bulbs instead of seeds, or by the seeds themselves germinating on the plant, instead of falling, as they usually do; -- opposed to oviparous
