Omg, Are These White Round Worms In My White Shrimp Head? Pic

And here is a question to those who pet shrimp, pic below:
Do shrimp developed mature ovaries first, and then it become saddle?
If so, then maybe that is undeveloped ovaries.
I found a pic online of a shrimp that have white saddle. The white mushy blob like the one I see in my devein shrimp.

They develop kind of what are like ovaries, its more like a massive amount of very small eggs that becomes the saddle. Once fertilized they become large eggs that you can see individually. I doubt it's the saddle you're seeing. It really depends on what kind of shrimp that is and how large. Could be some accessory organs or part of the digestive tract or the worms as you suggest.
