Exempel på hur man kan använda VIVIPARITY i en mening

• The name "viper" is derived from the Latin word vipera, -ae, also meaning viper, possibly from vivus ("living") and parere ("to beget"), referring to the trait viviparity (giving live birth) common in vipers like most of the species of Boidae.
• Recently, it was discovered that some species even exhibit viviparity, where the embryos are incubated in the coelom of their mother's tube and the "hatch" to produce feeding actinotroch larvae.
• This is the reproductive mode of insects such as tsetse flies (Glossinidae), keds (Hippoboscidae) and bat flies (Streblidae and Nycteribiidae), as adenotrophic viviparity is a characteristic feature of the superfamily Hippoboscoidea.
• The exact mode of reproduction ranges from ovoviviparity through to viviparity, and in some species, oophagy is known, as well.
• It exhibits a specialized form of aplacental viviparity with oophagy: the females produce a single capsule in each uterus that contains 30–80 ova, of which one ovum develops into an embryo that consumes the rest of the ova and stores the yolk material in its external yolk sac.
• Like other stingrays, the estuary stingray exhibits aplacental viviparity, with the developing embryos sustained initially by yolk and later by histotroph ("uterine milk") produced by the mother.
• The Opisthopatus genus exhibits matrotrophic viviparity (also called ovoviviparity), in other words the eggs remain inside the uterus until hatching, so hatching and birth happen simultaneously.
• In particular, this genus exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta.
• This genus exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta.
• No populations of this skink exhibit normal scincid oviparity behavior with greater-than-30-day incubation periods, which could further indicate this skink is truly making the transition to exclusively viviparity.
• It is one of the three major modes of elasmobranch reproduction encompassed by "aplacental viviparity", and can be contrasted with yolk-sac viviparity (in which the embryo is solely sustained by yolk) and oophagy (in which the embryo feeds on ova).
• In histotrophic viviparity, the zygotes develop in the female's oviducts, but she provides no direct nutrition; the embryos survive by eating her eggs or their unborn siblings.
• Traditionally this variety was classified into three modes, oviparity (embryos in eggs), viviparity (young born live), and ovoviviparity (intermediate between the first two).
• Velvet worms in this genus exhibit matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta.
• This genus exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta.
• This genus exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta.
• sedgwicki species complex exhibit matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta.
• Fertilization occurs by means of haemocoelic insemination and reproduction occurs by means of haemocoelous viviparity.
• The large egg with a relatively thin eggshell may indicate a reproductive investment linked with gigantism, and lepidosaurian viviparity, in which an egg is laid and hatches immediately.
