A black rat snake WILL "rattle" its tail if its afraid or angry. They'll coil up and strike, similar to a cobra as well (as will many other harmless snakes). But they're WAY more afraid of you than you are of them, so they have to do SOMETHING to defend themselves!!
Another myth about black snakes is that they will breed with copperheads and create venomous hybrids. Alot of the old farmers around here believe this, I'm assuming because young black snakes do have that grey/white/black diamond pattern before they go all black. But black snakes breeding with copperheads and producing offspring is genetically impossible. Black snakes are egg layers, and copper heads are live bearers. Can't be done.
