canebrakes are considered sub tropical rattlers and are a sub species of timber rattlers and yes they have that same beautiful coloration with high contrast and that orange line down the back .
they tend to grow many times larger than timber rattlers as well .
haven't seen one in many many years , but way back when I would run across a few in the swamps on my hikes to the water to ketch fish and swamp bunny hunts and so on and so forth .they always stayed far away from any population of people .
