The 36 pages that link to Viviparity, each with the reason it gives.

• OviparityCompared with: It contrasts with eggs developing outside the parent after being laid.

• AmnioteRelated: Some amniotes replace egg-laying with internal development and live birth.

• Amniotic eggCompared with: Live-bearing mammals show that amniotic development does not require a laid egg.

• External fertilizationCompared with: It contrasts with the usual external development associated with external fertilization.

• IncubationCompared with: Viviparity shifts embryonic support inside the parent rather than relying on an incubated egg.

• OvoviviparityCompared with: Unlike ovoviviparity, viviparity involves live birth rather than hatching from retained eggs.

• Internal fertilizationRelated: Internal fertilization may be followed by prolonged development inside the parent.

• IchthyosauriaRelated: Live birth let ichthyosaurs reproduce at sea without returning to land to lay eggs.

• OvipositionCompared with: Viviparity retains developing young internally instead of depositing eggs externally.

• AphidRelated: Many aphid females give birth to live young, accelerating colony growth.

• Marsupial pouchCompared with: Marsupials are viviparous, but their short internal development makes postnatal pouch care distinctive.

• Sea snakeRelated: Most fully marine sea snakes give birth at sea rather than laying eggs on land.

• Marsupial reproductionNarrower topic: Marsupial birth is one form of live-bearing reproduction.

• Brood pouchCompared with: Pouch brooding involves parental retention, but does not always provide nourishment like viviparity.

• GestationNarrower topic: Gestation is the developmental period characteristic of viviparous reproduction.

• YolkCompared with: Some viviparous embryos receive substantial maternal nourishment rather than relying mainly on yolk.

• CaecilianRelated: Several caecilian species nourish developing young internally before live birth.

• EomaiaRelated: Eomaia's eutherian affinity bears on the early history of live-bearing mammals.

• PlacentaliaNarrower topic: Placentalia is a major living radiation of viviparous mammals.

• BoidaeRelated: Many boas give birth to live young rather than laying eggs.

• FetusNarrower topic: Fetal development occurs within the broader reproductive strategy of viviparity in many mammals.

• Requiem sharkRelated: Many requiem sharks give birth to live young after internal development.

• Bull sharkRelated: Bull sharks give birth to live young rather than laying eggs.

• IchthyosaurusRelated: Ichthyosaur fossils preserve evidence that these reptiles gave birth in water.

• Animal embryonic developmentCompared with: It contrasts with embryos that complete development in eggs laid externally.

• Cownose rayRelated: Female cownose rays give birth to live young after internal development.

• Fire salamanderCompared with: A few populations give birth to fully developed young, unlike the more common larval birth.

• Viviparous lizardNarrower topic: This broader reproductive strategy gives the species its common name.

• AnguinaeRelated: Several slow worms give birth to live young rather than laying eggs.

• Blue sharkRelated: Blue sharks give birth to live young after embryos develop within the uterus.

• Blue-tongued skinkRelated: Female blue-tongued skinks give birth to live young rather than laying eggs.

• Fish pregnancyNarrower topic: Fish pregnancy is one form of viviparity, though the embryos’ sources of nourishment vary.

• HoundsharkRelated: Many houndsharks give birth to live young rather than laying eggs.

• Jackson's chameleonRelated: Females retain developing young and give birth instead of laying eggs.

• PotamotrygonidaeRelated: Freshwater stingrays give birth to live young rather than laying eggs.

• SebastinaeRelated: Many Sebastes species release live larvae rather than laying eggs externally.
