"Yōkai Daizukai, an illustrated guide to yōkai authored by manga artist Shigeru Mizuki, features a collection of cutaway diagrams showing the anatomy of 85 traditional monsters from Japanese folklore."
15 anatomical images (cow, goat, horse, dog, lion) from a series of publications from 1898 and 1911-1925 by Wilhelm Ellenberger and Hermann Baum with illustrations by Hermann Dittrich.
Not that morbid, actually. Very anatomical though.
Theoretician of the synapse, and incredible medical illustrator.
Couldn't type "posthuman" into the tag field fast enough.
