Pygmy Sperm Whale Skull

^{Ink and acrylic
anterior view of Kogia breviceps skull, after my own reference photos.
Minor digital editing, I had to scan it in sections.}

Notice the skull forms asymmetrically. One of the nares has grown to be dominate, a single blowhole. It is certainly not obvious from outside the animal, so I find their skulls very interesting and beautiful.
