Hatchlings vs. "neo-nate"??

[mtolypetsupply]

I was wondering if I have my info correct, and also correct terminology.

It's my understanding that although garters appear to be "born live" if you're watching the process, they are actually internally incubated in the egg in the mom. The egg membrane is still present when "born", albeit very thin and not looking at all egg-like. Am I correct in this?

Now, for me, this begs some questions. Are they born or hatched? Are they hatchlings? Neo-nates? Juveniles? When do they transition from hatchling/neonate to juvenile?

I know, I should probably buy a book on this, but I have too many books already, and not enough room for garters so I figured I'd ask y'all!

Technically hatched, but nobody's going to murder you for saying that they're born.

The word neonate is usually used for animals less than one month of age. Technically, neonate does mean newborn, but most of the time it's used to describe humans less than one month old. Animals are also juveniles from the moment they're born/hatched until they're mature.

I did not pay attention in biology class, but as far as I recall from growing up on the dairy, mammals are in a thin membrane during developement as well, which breaks right before or during birth, and they are definitely considered live birth. I've pulled that sack off the mouth of newly born calves many, many times. Then the cats and dogs eat it.

I'm not sure what the difference is between them and garters (as far as live birth vs egg birth). I'm sure there is one- I just dont know what it is.

In ovo-viviparous reptiles there is no ubilical cord... although the babies appear to be born live, they are in fact incubated in a membrane-like 'shell', and delivered at the moment of hatching. There is no physical connection to the mother.

Ah, thanks James.

So, does this mean gravid snakes can smoke and drink without affecting the babies?

You betcha! Actually, I'm not totally sure about that.....

You never know............Chili looks like she's had some pretty wild parties out there. Although that might explain a couple of her kids.

Sure! Pate and soft cheese are on the menu too!

The reason I asked is someone posted on fauna classifieds "hatchling/juvie garters wanted". One of the resident "know it alls" had to "correct" them and tell them they were live birth. I knew he was not as smart as he thinks he is.

He's not really wrong..... ovoviviparity is generally referred to as 'live-birth'.
