Are there any differences between the species (like motoros, leos, pearls, retics etc.) in design?

I have used toe nail clippers for a dog to trim a stinger one time because it had some netting stuck on it. I have never done anything to my stingers except let them dry out. The ones in my pic are the same way they were when I pulled them out of the tank.
