Jockey

Jockey, by definition, refers to an entity riding another entity.

Classification
It refers to a naturally spawned mob riding another mob. Jockeys are named based on the mob being ridden. They also follow the spawning patterns of the bottom mob. The mob on the top controls the mob on the bottom, overwriting its AI and speed attributes. Jockeys cannot be separated unless one of the mobs are killed.

Jockeys can be spawned manually with the command (also see Tutorials/Summoning jockeys).

Official
These compound mobs are officially named by the developers of Minecraft.

Unofficial
These compound mobs don't have an official name, and were never referred to be official jockeys by Minecraft developers.
