I have a male and a female and both of them are just the sweetest snakes ever and a total joy to watch and handle. Neither one of them have ever shown any signs of aggression or defensiveness. They say that there isn't sexual dimorphism in Woma Pythons, but my female has always been way bigger than my male for some reason. It is said that Womas can reach up to 8 1/2', but 4' - 6' is definitely much more common. Mine are only about a year old, so they still have a lot of growing to do...
