Went to Just Pets in NY today, they had a few oddballs, but the most odd thing was the 8 or so inch silver. When it's mouth was closed, its lower jaw honestly came a half inch past its the top of it's head (and no not its barbels, its actual jaw). Weirder yet, it's jaw didn't look like it had been damaged, it looked like it was naturally born this way, yet I've never seen another like this. I was just wondering if this happens frequently or not, and if so why? Also sorry for not having a pic, I didn't even think to take one untill I was halfway back.
