Freaky snail situation

[DKoKoMan]

Weird!! What kind of snail is that?

[Dash]

I think it's a turbo? It's a good size, been in my tank for about a year. I haven't read anywhere that they carry babies on their backs.
Here's a side view

I'm with you! Looking at it makes it look like they are definitely riding on the back. I know before o transferred my tank over I had a bunch of babies but they were just on the glass of the overflow.
