Exactly. Plus, y'know, the fact that they have faces, vocal cords, etc. I mean, if you're ignoring massive physical differences, you could just equate all birds, all fish, whatever.

Perhaps you meant that an un-Awakened Naga would be broadly *like* an anaconda?
Not that it has anything to do with the topic.

Re: hybrids, they *have* classifications. A tiger/lion is either a tigon or a liger, depending on the parent sexes. A zebra/horse is either a zorse or a horbra. These are sterile (mules), so they're not a species. A half-wolf is wolfdog, and they're both already the same species in the first place.
