I saw a theory on this wiki once about the black, "regular" Nargacuga being an all-female species and the Green one the all-male species... meh, I always assumed that monsters, unless being specifically refered to as female like Rathian and Lunastra, could be from both genders... but the thought may come from their names. Najarala and Nargacuga do sound like names for a female.
