Well, something's gnawing on it, but not stink bugs. As you've learned, only skin deep & is fine to eat.

It looks like scratches on a cucumber. Was it rubbing on a trellis or the ground as it grew?

Those are sort of old wounds that have healed.
Maybe some slugs (or other insects scratched/ ate the skin.

Thanks! they are really not hurting anything... so for now I'll leave them be... there is a insect war going on out there (I've seen some pretty amazingly huge insects out there this year) so hopefully there will be some casualties in my favor.
