today i went fishing at a local pond and one my last cast i got my only fish of the day.. maybe a 3-4 lb largemouth..but this one had a thin narrow lateral line like a snook rather then the common bold zig-zag..          explanations??

Bass can adjust amount of patterning and lightness/darkness to match surroundings, or likely to communicate.

Bass are also individuals. Some are unique. I saw a female on a bed this spring that was unique. She had four stripes, alternating with pale ones -she looked like one of those small round striped watermelons!  She was so gravid she was nearly round, and very buoyant, the male could push her around like a balloon.

Also, there are some notable regular color pattern changes I see during the spawn that must mean something, but I'm at a loss to explain what .
