Please tell me if it’s male or female. I’m sorry the photos are terrible. I sat for 10 minutes trying to get these!

I would want to say if there's no "V" shaped pleopods underneath the stomach, then that's a female. Never kept them, so not really familiar with sexing them.

It's pretty easy to sex crawfish, but the photos aren't helpful.
