[Star Wars] [SPOILERS] How common are unidentified species?

In the mandalorian series we see the people first seeing the kid pretty blasé about it, in EP 5 the mechanic gives this a nod by telling a droid she has no idea of what the kid is, so I can imagine in smaller worlds without large traffic people not knowing about a species makes sense, but even in somewhat larges ones with more traffic, people are still uncaring about the kid's species.

Is the sense of wonder and discorery gone? Or are unkown species that common that people don't really ask about it?

It's a big universe, with a ton of species living in it, and there are probably very few people, if any, who know all of them. Seeing a species you don't recognize doesn't mean it's an undiscovered oddity, just a species that you've never seen before. Living on a world with a lot of travellers coming and going, you probably get used to it.
