Here's a more detailed explanation.
Ovoviviparity is a method of animal development in which the young grow in eggs inside the mother's body, and the mother gives birth to live young. Ovoviviparity is seen in some fish, reptiles, and amphibians around the world. There are a variety of reasons why animals might have evolved to give birth this way, and ovoviviparity is a topic of some interest among researchers as a result. This method of reproduction is also intriguing to many laypeople, since most people assume that egg-layers cannot give birth to live young.
Most people are familiar with vivipary, in which an animal gives birth to live young after it has developed in the uterus for a period which can range from weeks to almost two years, in the case of elephants. Humans, for example, are viviparous animals. Conversely, ovoparity, in which an animal lays eggs and the young hatch out, is the method of reproduction used by many birds, reptiles, amphibians, and others. Ovoviviparity is a blend of both methods, and it is much more rare.
The primary difference between ovoviviparity and vivipary other than the obvious presence of eggs is that ovoviviparous animals do not provide nutrition to their young through a placenta, as is the case in viviparous animals. Instead, the developing young inside the egg feed on the egg yolk, just as their ovoparous cousins do. The mother's body provides protection for the eggs, allowing them to develop without the risk of being eaten or trampled by other animals, and she also provides some gas exchange to the developing egg.
The advantage to ovoparity is that animals can lay large clutches of eggs, ensuring that at least some of their young survive. Ovoviviparous animals can only incubate limited numbers of eggs at a time, typically giving birth to no more than six young. Therefore, the young are more precious to their parents. In contrast with the young of viviparous animals, ovoviviparous young are typically also very well-developed and precocious, able to navigate the world shortly after birth, although they may still require guidance from their parents.
In some ovoviviparous animals, the young are born in larval form, and they metamorphose outside the bodies of their parents. Others are born fully formed, although they may require several weeks or months to mature to the size of their parents. Sharks are among the most notable of animals which exhibit ovoviviparity, although there are numerous other examples in the fish, reptile, and amphibian world, including manta rays, vipers, and some toads.

Deuce is watching!
I have known Vetusvates since he came to the site. I would find it unfathomable that his intent was to personally attack. He is an intelligent caring person with remarkable wit. I will defer to him to explain his intent but rest assured I highly doubt it was to disparage.

Sometimes intent is lost in a message, I'm have no doubt he's a great guy nor do I judge, he made no personal attack to me but my opinion is this ........drop it, he has apologized to the recipient so just move forward, no harm no foul !

Thanks, tsst.
Much appreciated.
But then, knowing a bigger picture, having seen a bigger picture, having watched a bigger picture for years rather than a few weeks....increases one's credibility AND latitude in expressing himself.
Again, I appreciate your insight from years of interaction.
And I must say, you and I both know who the Moderators of the forum are, how they came to be, what their purpose is, and trust them to direct us when to crank it up AND when to shut it down.
They know their job, when to let us iron out our own wrinkles, and when everything has deteriorated to a point of calamity---such that they need to step in and start their jobs as Mods directing traffic.
The seniority of their wisdom, and the wisdom of their seniority is broad, wise, profound, and magnanimous.

Mice! They taste so nice!
Actually, periods (menstruation) are unique to humans and the great apes. (Gorrilas, Chimpanzees and Orangutans) So whilst other mammals have fertile periods, or come 'into season' and you may be familiar with seeing a dog or a horse have a blood-tinged discharge at that time, it's not quite the same physiologically.

I had a female Great Dane that I needed to put a Diaper on when Aunt Flow was in town.

Yep, but that is not the lining of the uterus being shed, which is what a period is. So no periods in snakes, crocodiles, rats, chickens, dogs.......only us apes.

I have known Eric for quite a few years on this site. And I know him as a very caring and intelligent person. He would never attack anyone in such a way as he was accused. I think this is merely a case of misunderstanding. I saw what he said as a form of humor as well.

Thank you, Steph. Nothing like having friends who "know" you and will speak up on your behalf.
Fascinating, Nanci. Both my grandfathers raised cattle. And we have had horses...and the mares pestered even the geldings when they were "ready". Could be humorous to watch.

I added the SmiliesAwkward,...naah.
Stupid,...hung jury.:nyah:
Anthropomorphizing,...yes. :cheers:
Go back off topic for a minute ...........
At my age do I feel a little childish using Smilies, Yeah But I do for this very reason. I tend to use a little humor in some of my responses and without putting a Smilie attached to it then it could be lost in interpretation. The written word is sterile and open to subjectivity without some indicator of how it is intended.
I could see the humor it was intended but I also see how it could be easily mistook.
Lastly, vetusvates, could you please include a link to the "vetusvates to English" translation page for us that are not up to speed yet with the vetusvates language :cheers:
:laugh01: Humor
Back to the OP's question......
I've owned 100's of reptiles and it never occurred to me if the females menstruate.
Good question. It made me go HUH?????

Yeah.....feeling too old to use smilies is very much empathized with. I feel silly using them sometimes. But seriously...much is lost in black and white type print that would be softened by smilies.

ETA : I made it back to rep daddio for what is, for me, the quote of the day. In blue above.

Nanci, one grandfather told us (cousins) the cows were "fighting". But the other grandfather told me in calm wise terms what was happening. He even taught me how to tell when transpired the exact instant that the bull and his respective cow "accomplished" their connection.
Frogman, I'm a city boy too, but it was always great to get away to my grandparents' in the country as a kid growing up. More lizards, snakes, turtles, and yes...frogs.

That didn't work for me, I grandparents on my dads side lived in a house above the jewelry store that they owned in Carteret, NJ. (same city Jerry Lewis lived), my grandparents on my mothers side lived under the "L Train" tracks in Philadelphia. It wasn't until I hit my 40's that I really started enjoying animals and it took me to hit my 50's and a life threatening disease to really find my love for Snakes and Frogs. I call my snake and collection my mid-life crisis.
