I thought they looked like 3 girls, esp the 2 upper ones, based on tail shape & my experince with NC Nerodia spp.
Ive never seen rhombifer until now.
That must seem pretty weird to "regular people" that snakes scared the hell out of you BECAUSE YOU THOUGHT THEY WERE FISH ! (But then i guess you probably dont compare yourself to regular people all that much, esp at 4am covered in fish blood).
I'm used to pulling gar into to boat with their toothy mouth open at me. But when I pull a gar in that turns into a ~52 inch un id'ed snake as its open mouth is an inch from my leg I yell almost loud enough to scare nutria watching me from the bank. Now I can add groups of disgruntled water snakes to the list of things that may attack me while reaching into the water to pick up my traps in the middle of the night.
