History Main / PregnantReptile

SubTrope of ArtisticLicenseBiology. Contrast with WhaleEgg, in which a mammal reproduces the non-mammal way. Can go hand-in-hand with NonMammalMammaries. InterspeciesRomance examples count too if the character giving birth to the non-mammal is oviviviparous, but the partner not giving birth is viviparous (never vice-versa though). See also MrSeahorse for another trope about characters getting pregnant/giving birth when they shouldn't be able to.

** Prehistoric marine reptiles, such as [[UsefulNotes/StockDinosaursNonDinosaurs plesiosaurs, ichthyosaurs, mosasaurs, and pliosaurs]], also reproduced this way.

* In ''WesternAnimation/TheLoudHouse'' episode "Friends in Dry Places", a snake is said to have given birth in Lincoln's sleeping bag. Justified, since some kinds of real life snakes really do give live birth.

* ''Film/AlienResurrection'': It's unclear exactly what taxonomy the [[StarfishAliens Xenomorphs]] would belong to, but they're *clearly* not mammals since they reproduce through eggs and do not rear their young. However, because of retaining some of Ripley's DNA after gestating inside her, the new Queen ends up birthing a life newborn.

* The above image is from ''Literature/{{Froggy}}'s Baby Sister'', which has Froggy's mother shown pregnant with his baby sister. (His baby sister is then shown [[FurryReminder drinking fly mush]].]]

In spite of the title, the non-mammal does not have to be shown pregnant, just birthing live young.

* In ''Webcomic/EnnuiGo'', [[spoiler:Ally is shown to be pregnant in the final right panel of "[[http://ennuigo.thecomicseries.com/comics/1359 Those Guys]]." As a reminder, Ally is half-alligator.]]

Sometimes may be {{justified}} if the non-mammal is stated to have laid and incubated the egg inside them, which is TruthInTelevision (see RealLife section below).

** Certain shark species are also truly viviparous, nourishing their developing young with placenta-analogues.
* The same thing above can be said for amphibians, including a few frogs and toads, the fire salamander and several species of caecilians, give live birth instead of laying eggs.

* Hutts from ''Franchise/StarWars'' are implied to be reptiles or amphibians, [[MrSeahorse and are male, yet they are able to get pregnant and give birth.]]

* ''WesternAnimation/SpongebobSquarepants'':
** In the episode "Truth Or Square", it is revealed that Spongebob's first time tasting the Krusty Krab was when his mother was pregnant with him. He is shown in her womb, being fed Krabby Patties through an umbilical cord. While sponges don't actually give live birth, they ''are'' biological hermaphrodites and are capable of sexual reproduction in addition to the more-well known method of asexual budding that the show itself popularized much earlier in its run.
** In the episode "Pets or Pests", Spongebob adopts a worm whom he thinks is a male, but then she gets pregnant and gives live birth. Spongebob then spends the rest of the episode trying to find someone to adopt the baby worms.

* In EnnuiGo, [[spoiler:Ally is shown to be pregnant in the final right panel of "[[http://ennuigo.thecomicseries.com/comics/1359 Those Guys]]." As a reminder, Ally is half-alligator.]]

* Though not truly live birth, there are some snake, lizard, and shark species which lay and incubate their eggs inside their bodies, in which then their young hatch and come out, giving the appearance of live birth.

* Aphids are tiny insects, that not only incubate their eggs, but they are basically born pregnant.

* Lara Le from ''ComicBook/ArchieComicsSonicTheHedgehog'' is an echidna and has gotten pregnant before.

This trope applies to monotremes, that special order of mammals which lay eggs, living creatures that reproduce by splitting up, mythological creatures that are not usually depicted as giving live birth, and even an AnimateInanimateObject can qualify if they are shown getting pregnant or giving birth.

** In the episode "Truth Or Square", it is revealed that Spongebob's first time tasting the Krusty Krab was when his mother was pregnant with him. He is shown in her womb, being fed Krabby Patties through an umbilical cord, even though sea sponges are asexual and reproduce by splitting up-- something the show itself has pointed out in other episodes.

* Hutts from ''Franchise/StarWars'' are [[MisterSeahorse male]], and are implied to be reptiles or amphibians, yet they are able to get pregnant and give birth.

* Aphids are tiny insects, that not only give incubate their eggs, but they are basically born pregnant.

* In ''WesternAnimation/HotelTransylvania2'' Mavis, a vampire, gets pregnant and gives live birth to Dennis, even though most other media typically portrays vampires as becoming vampires via a bite, rather than reproducing.
