Schematic teaching diagrams drawn in code: they show organ relationships and differences, not measured dimensions.
What the evidence labels mean
Evidence labels used throughout: Established well documented in the listed sources · Approximate a typical value or range · Varies depends on individual, breed, season or population · Not available no verified source for this project · Speculative fiction, not biology. No anthropomorphic or fictional anatomy is drawn in the atlas; speculation is confined to the Hybrid lab.
Anatomy atlas
Choose a species, sex, view and layers. Select any structure, in the drawing or in the list, to read what it does and how it differs between species.

How to read the atlas
Silhouettes are drawn at different scales so the organs stay legible. The internal drawings use the canid, felid or equid body plan; the three canids (fox, wolf, dog) share one plan because species-specific anatomy was not verified for the fox and wolf. Relative proportions such as “long horns” or “short horns” are qualitative.
Process studio
Step through a process, jump to any stage, or press play. Timings are approximate unless labelled Established.
Tissues and histology
Cell-level motifs for the main reproductive tissues, and organ cross-sections for any structure.

Species comparison
Compare any two species, or all five at once. Every cell says how well it is supported.
Hybrid lab Speculative
A fictional sandbox. The real-biology verdict is shown first and separately; the traits below it are random worldbuilding draws, not genetics.
Trait choices are random picks from illustrative lists for each parent. They are not genetic probabilities and not predictions. A real inheritance model needs defined genes, alleles and species-specific data.

Known limitations
- All diagrams are original schematics. Silhouettes are not to scale or to one common scale; relative proportions inside organs are qualitative, not measured.
- Fox- and wolf-specific anatomy was not verified. Their tract plan is assumed from the dog and other carnivores and is labelled Approximate.
- Cat implantation timing, cat vaginal cytology and the extent of the cat ovarian bursa have no verified source here and say so.
- Textbook-level statements cite textbooks that were not consulted directly while building; check them against your edition.
- Links were confirmed from search results, not by live link checking, and some pages are paywalled.
- This is a learning tool. It is not veterinary guidance; labour or breeding problems need a veterinarian.
