I've been around a number of achondroplastic dwarfs during my science days and they are very different in appearance, with the short limbs and large heads than this fellow, but there are different causes of dwarfism.
RIP little guy.
Off the top of my head there are anchondroplasic,pseudo-anchondroplasic,pituitary and primordial dwarfs.
Anchondroplasic are ones with the bulbous heads.Pseudos don't have bulbous heads and are supposed to be quite jolly, Pituitary dwarfs have normal proportions.Primordials are the smallest.
Dev was a primordial dwarf.
All beside the point . RIP to the little man.
