I have seen quite a few of them. Most of the time it means they have been in the shallow water for quite a while, as opposed to moving in and out of the shallows.
It can also be due to the color of the water. Bass that come out of dark, tannic waters tend to be darker.
I suppose in a few cases it could be some do have a genetic tendency to being darker.
