You are correct. It is caused by incubation. Too hot to be precise. In other species, the tail is missing altogether. I have only studied outer appearance in relation to incubation, and have no information as to any ill effect or damage to the inside of the animal. Snappers, at least the common snapper, is the most tolerant of high temperature. North American wood turtles produce the most defects(of those I've studied) if the temps are not exactly perfect. It does not bode well for many turtles if global warming continues at its current rate. that is unless they can adapt quickly. Snappers, it seems, are the least prone to defects from temperature. Most of the time, they just are Dead in shell rather than a visual defective hatchling, unlike many other species. I have not studied the alligator snapper, but since defects in the tail seem to be found with every species I've studied, I would hazard a guess that this is the cause. Pay close attention to the eyes. They are usually smaller when there is a tail defect.
:Here's a picture, sorry I don't know why they has tails like that my guess is incorrect incubation.
