Yes and No. They are in the same family, but the canebrake usually has a rust-colored/reddish stripe down its back. They are indiginous to North Carolina, down south to Florida and as far west as Texas. Regardless, both are venemous and can be dangerous if threatened/cornered, stepped on. Steer clear of them, they are not likely to attack without being provoked. I have heard that the canebrake venom is more intense and dangerous than the typical timber rattler.
