Some sharks are ovoviviparous (they make eggs, but they have the eggs hatch inside their reproductive tracts). The inner turmoil is real. Imagine your offspring eating each other before they leave your body! Mom deserves a break

Lizard of the day: Limpopo girdled lizard!
A Southern African species! They are arboreal and are pretty good at climbing despite their rather tiny hands! They're ovoviviparous and feed mostly on winged insects, including winged termites and ants!

@catwif3.bsky.social "ovo" is a pretty good approximation of my face perking up reading this about ovoviviparous mermaid bio

......... also the implications of the amount of species difference of xie lian having an ovipositor is. like that seems to imply a sort of seahorse-like ovoviviparous approach to breeding whereby his species might have a "womb"/pouch/chamber for holding eggs until they hatch for live birth,

Damn, in Vertebrate Reproduction it was always something like "Ovoviviparous". You were tough on us older siblings.

Lizard of the day: Mayan tropical night lizard!
A Mexican species! They're called nocturnal scorpions in Spanish, although they don't sting with their tails at all. Like other night lizards, they're ovoviviparous and nocturnal!

If you're referring to internal development of embryos, that's MUCH earlier than mammals. It's evolved >150 times, in sharks, reptiles, sort of all over the animal world. It's just a sort of delayed egg laying in most of those species (oviviviparity).
There's also various forms of 'matrotrophy'..

This western blue-tongued skink was spotted on a recent field trip in the AW region. Blue-tongues are among the largest members of the skink family. They are ovoviviparous – their young develop in eggs and hatch inside the mother’s body and are then born live.

Fun fact about hissing cockroaches is that they are ovoviviparous, which means they lay eggs that they incubate in their bodies until the young hatches, at which point they’re born live

Ovoviviparous reproduction is when embryos develop inside eggs that remain within the mother’s body.
This type of birth occurs in a few chameleon species, such as the Jackson’s chameleon (Trioceros jacksoni) from East Africa.

Lizard of the day: Peers's girdled lizard!
A South African species! They have a pretty well armored skin! They mostly feed on caterpillars and other insects, and are ovoviviparous. Their skin tone may vary from grey to black.

They owe their name to their peculiar pose when basking in the sun! Their scientific name, Smaug Giganteus, was taken from the legendary dragon from TLotR! They're South African, dig their own burrows and are ovoviviparous!

Ooh, I didn't know it about garter snakes either (despite them being the main native snek around my home), I just knew about boas being ovoviviparous from when I did reptile handling at the zoo. Learning lotsa cool snake facts today, thanks!

Tiger sharks are the only sharks in the family Carcharhinidae that are ovoviviparous, which means they grow their embryos internally and nourish them from a yolk sac before giving birth to live, independent young.

Today's aquatic friend is: Lamna ditropis, the Salmon Shark! these ~7' weigh around 400lbs on average. They are also ovoviviparous, which means they give live birth! They are capable of temp. regulation, a rarity among fish. Cold blood from their gills is heated by warm blood from their body. #fish

Pretty guy and a nice fly...
A the noon fly, Mesembrina meridiana.
It lays eggs in cow dung, feeds on nectar and pollen, and is ovoviviparous.
It contributes to controlling the populations of other coprophagous insects.

Do you plan to hatch them internally an ovoviviparous manner like many snakes and sharks or do you plan on laying them once they’re ready?
