Sperm whales of the Harvard Museum of Natural History

Check this baby out:
I know, I know what you’re thinking. “Enough with the vulgar overexposed skull of this beast, Taylor”, you cry: “Show us its zygapophyses!”
But of course.
This is from the anterior part of the tail, in right lateral view: the vertebrae that you see here are the third to seventh of those that carry chevrons.
The hot news here is of course that sperm whales go to all the bother of developing zygapophyses, right up at the top of their neural arches, down in a region of the body where they don’t come close to articulating and are of no conceivable use.
Anyone know why? Care to hazard a guess?
