Of course, snake hunters go to a densite looking for Rattlesnakes.  Timber Rattlesnakes are our largest snake species, exceeding 4 feet long and some monsters approach five.  Coupled with their length, Rattlesnakes are a heavy bodied species.  There are two color phases.  The color phase shown here is what is known as the "Yellow Phase" and there is a very dark variety, "Black Phase."  Juveniles hatch somewhere in between.
