* For animals that walk on four legs (quadrupeds): The bottom is usually referred to as the ventral side, which is the underside of the animal.
* For animals that walk on two legs (bipeds): The bottom is typically considered the posterior or dorsal side, which is the back of the animal.
However, the term "front" is usually used to describe the anterior side of an animal, which is the head and chest area.
Here's a breakdown:
* Ventral: Bottom or underside
* Dorsal: Top or back
* Anterior: Front or head
* Posterior: Back or tail
It's important to consider the animal's specific anatomy and movement when determining what the bottom or front is.
