- Direct development and viviparity have evolved in all three groups of Lissamphibia: frogs, salamanders and caecilians.
- The evolution of viviparity, which frees the mother from having to deposit eggs on land, and the tailfirst birth of the young imply that Carsosaurus was well on its way to a more fully aquatic lifestyle.

Example sentencesExamples
- During the summer months, pea aphids reproduce parthenogenetically and viviparously.
- Tiger Sharks reproduce viviparously, which means that like mammals, the give birth to live young that have been nourished by a placenta.
- After several months of gestation the young are produced viviparously and the female carries them around on her back for a week or so, beyond their first instar stage.

viviparousness

noun

Origin

Mid 17th century: from Latin viviparus (from vivus 'alive' + -parus 'bearing') + -ous.

viper from early 16th century:
Some vipers give birth to live young which have hatched from eggs within the parent's body, whereas the eggs of most snakes are laid before they hatch. The name viper derives from the fact they are viviparous (‘producing live young’ M17th), coming from Latin vivus ‘alive’, as in vivisection (early 18th century), and parere ‘to bring forth’, the source of parent (Late Middle English). The phrase a viper in your bosom, ‘a person you have helped but who has behaved treacherously towards you’, comes from one of Aesop's fables in which a viper reared close to a person's chest eventually bites its nurturer. See also adder, snake
