An aphid giving viviparous birth, an unusual mode of reproduction among insects. In animals, viviparity is development of the embryo inside the body of the mother, with the maternal circulation providing for the metabolic needs of the embryo's development, until the mother gives birth to a fully or partially developed juvenile that is at least metabolically independent.
The viviparous lizard, or common lizard, (Zootoca vivipara, formerly Lacerta vivipara) is a Eurasian lizard. It lives farther north than any other species of non-marine reptile, and is named for the fact that it is viviparous , meaning it gives birth to live young (although they will sometimes lay eggs normally).

Animals make use of a variety of modes of reproduction to produce their young. Traditionally this variety was classified into three modes, oviparity (embryos in eggs), viviparity (young born live), and ovoviviparity (intermediate between the first two).
Viviparous fish are fish that give birth to live young, the eggs develop whilst receiving nutrition from the parent.. See also:Category:Ovoviviparous fish - fish which give birth to live young which do not receive nourishment from the parent whilst in the womb.
Watsonia meriana, near the end of flowering, has cormlets that eventually drop and root. Red mangrove seeds germinate while still on the parent tree.. In plants, vivipary occurs when seeds or embryos begin to develop before they detach from the parent.
Life on Earth would be so dull without animals. Lucky for us, there are more than 8 million different species of them on the planet, many of which we might never encounter in our lifetime. From ...

Males are 2 mm smaller than females of the same age. The shell colour is dark greenish brown or greyish yellow, with three reddish brown spiral bands.
Ovoviviparity, ovovivipary, ovivipary, or aplacental viviparity is a term used as a "bridging" form of reproduction between egg-laying oviparous and live-bearing viviparous reproduction. Ovoviviparous animals possess embryos that develop inside eggs that remain in the mother's body until they are ready to hatch.
