These can get to 9', but I haven't seen one that length for 20 years. To many cars and people. My brother had rattle snakes in a big pen when we were young. I threw one of those 6 foot king snakes in and it ate a 4 foot rattler. I was kind of in trouble. The difference between these and the big rattlers is that the scales on this one are still small and the skin is still thin. Ill bet Eddie has some snakes that would eat them all. Justin
