Over 3 years in the making, this 120-page artbook bestiary includes the anatomy, behavior, and origins of over 20 amazing fantasy creatures. Each interconnected through a series of recorded histories, myths, and first-hand encounters that stress the value of exploration and curiosity in the face of superstition.

Here's a close up version of their feet-
 
Since centaurs cannot easily stoop their upper body to reach low lying plants they rely on a peculuiar method of ingestion to eat while on the move. Centaurs graze through grasping mouths on the base of their four hooves. These toothed orifices are attached to a length of esophagus-like tissue that runs the length of the centaur's limbs. The process appears to be automatic, and centaurs continue to graze even while they sleep.

Think of it like a foot-anus with teeth.
Centaur are already wildly impractical creatures, and it got worse when I tried thinking though how they'd eat. Having them bend their human faces down to graze was the stupidest looking thing I could imagine (not to mention impractical biologically). So I went with something a little more unusual, but potentially more elegant.
Remember, I'm having to sort of work backwards from concepts that don't make a lot of sense scientifically and explain how they work in fun/believable ways.
The fun part was imagining a whole lineage of feet eating pseudo-centaur in their evolutionary line.
