Informations on the organs and such of foxes and other animals?

Question

I'm trying to learn what I can about all the inner bodily workings of foxes and lynxes especially, but other animals as well.

Differences between the fox/lynx and human heart, stomach, and things like that.

Answer 1

Sounds interesting!   There may not be as many differences as you'd think.  The digestive tract and heart are quite similar among all three species.  Teeth will be different, in that the fox has a few more premolars and molars than the lynx, and the lynx has more incisors than the human (search "dental formula" for details.)  Reproductive anatomy is slightly different; you can expect the lynx to be fairly typical for all cats.  Foxes are more dog-like.  Good luck.
