Anyway, I didn't really give a proper answer earlier, so to clarify, the rankings of the yautja are as followed (from lesser to highest)
Unblood: A predator that has not yet been branded with the "sacred mark" of their first xenomorph kill.
Youngblood: Newly blooded hunters, having not held the title for very long, they are considered young adults in yautja society.
Blooded: An experienced hunter with a high degree of experience & hunting prowess, feared & respected by the majority of their society.
Elder: A small percentage of yautja are known by their brethren as Elders. These fearsome hunters have seen many centuries & in some cases, even a millenium of honourable combat. they are looked up to by the majority of their society as being the most experienced & deadly warriors found in yautja society.
(alternate rankings, not listed in order)
Arbitrators: The yautja law-enforcement. The predator's equivalent of the police. Their role in society is very much the same as the role of law-enforcement on earth, they keep the peace, & bring to justice the despicable & dishonourable.....
Bad Bloods: the lowest caste of Yautja society, considered criminals & vigilante's by their terms & standards. They do not abide by the honour codes of the majority of Yautja civilisation & would not take a second thought of killing an innocent child, woman, or other defenceless prey.
Hope I cleared it up
