Just dropping off to comment about UVB
Wolf, the evidence you tell us about nocturnal reptiles being spotted under sunlight or having burrows facing sundown are correct, but not in the way you think.
They are found there not because of the UVB need, but because of the HEAT they need.
Basking in nocturnal and carnivorous reptiles is related to temperature regulation.
Saying that they all benefit from UVB is a generalization that shoulnd't be done, for a group as large and as parafiletic as Reptilia
Not all reptiles benefit from UVB, but neither are they harmed. Some of them just don't need it nor they need to avoid it.
Snakes, for example, don't have any use for it, and their methabolism simply ignores UV. Even most diurnal snakes won't benefit from it.
