On dragon cave why are there two different appearances of black dragons
The skinny kind of black dragons are normal, while the bigger, more aggressive looking kinds are called "alt's" (alternates).
Alt's are rare, only obtainable from bred eggs, an hatchling alt black dragon can have two forms, sitting and curled. some players likes to prove that they have both and simply freeze them.
