MudWings are the biggest tribe, and also the strongest. This is generally speaking - sizes tend to vary. In a clutch of eggs, the Bigwings can be massive, standing a head taller than the others, whereas the smallest sibling could be small enough to stand on the Bigwings' head/shoulders (as was the case with Umber).

SkyWings are the tallest tribe and have the widest wingspan, but their slender builds mean they're much less strong than the other tribes.

IceWings are nearly the same height as SkyWings, but their bright scales and impressive array of spikes make them seem far larger.

SandWings and NightWings are about the same size, all slightly smaller than the latter three. SandWings tend to be more slender, built for stamina and long desert flights, whereas NightWings naturally are more heavyset.

RainWings are the smallest tribe. Like SkyWings, they tend to be quite slender, but unlike SkyWings, their bodies are soft and they tend to have little to no well-developed muscle. In spite of this, they're commonly regarded as the prettiest because of their scales.

SeaWings are the shortest tribe. Their thick builds make them larger than RainWings in mass, but their legs are short and their stance tends to be wide, causing them to stand lower to the ground. They're very long dragons, though, with bodies built to manoeuvre through water.
