What horse has one less vertebrae?

Arabian horses
Arabian horses don’t just look like they have shorter backs than other horses; they actually do. This is because they have one fewer vertebrae than other horses, as well as one less pair of ribs. Their shorter backs make them stronger because they have a better structure for supporting weight on their back.
