The Zandalari trolls, being the civilized, pureblood ancestral race, look much less monstrous, and actually stand upright. Forest and Ice trolls are notably larger and more muscular. Sand and Jungle trolls, including the playable Darkspear tribe, are hunched and lanky.
There are several sub-species of trolls, mainly differing by skin color but sometimes with more pronounced differences.All Trolls Are Different: In this case, a savage yet spiritual people with ties to the elves who happen to have Cuban and Jamaican accents.

Dragons, or at least the Aspects, seem to be undying as well.Their high elven cousins made this switch long before this, when they were exiled from Kalimdor and the lands to which their immortality was tied.
