The noun חיה (animal) and the noun בהמה (animal) are sometimes used as the name of a category and sometimes as the name of a species:

That is, the noun חיה sometimes will include all living creatures which are on land, even a bird.

And sometimes, it will include a חיה and בהמה alone.

And sometimes it will be a special name for creatures of the desert.

And moreover, the noun בהמה as a category name will also include the חיה. And sometimes it is a special name for an animal that dwells alone. And any place where the noun בהמה comes versus the noun אדם, it is the name of a category. And all is according to the context of the Scripture - that from the context, it is understood whether it is the name of a category or the name of a species.
