Anatomy is a noun for the physical structure of a plant, animal, and sometimes inanimate things such as a building or a script. There is no direct antonym for anatomy. A plant, a creature, or a plot may be 'formless' but its formlessness is its structure.
Questions about the anatomy of specific animals should be placed under the categories for those animals. There is also a zoology category.
One good vet anatomy book that isn't just pictures to memorize and actually explains anatomy is the Textbook of Veterinary Anatomy by KM Dyce. This is an excellent comparative anatomy book that is used by vet students in the United States.
