"Not really invasive, though we apparently have weird privacy intuitions so that might not go for everyone? Hm, biologically, most common differences - our physical sexes exist on a spectrum with three ends, and we don't all look like me, but our phenotypes don't vary thanks to inheritable characteristics, unlike most species. General phenotype is determined by astrological circumstance - I was born when our largest moon Himsu was waxing gibbous, our middle moon Kaeshi was a sliver of a crescent, and our smallest moon Azoko was waning crescent, so I'm mostly towards the sex-point that rounds off to 'female.' The constellation Kanzu was ascendant, so I'm the shape I am, and the planet Rymni was closest to apogee, so I'm furred in a certain pattern, and the wandering star Shianxo was in the first house, so I'm yellow."
"We put a lot of importance on the stars, because they determine - well, everything. We're mostly nocturnal, though a few are more diurnally adapted - that depends on a combination of shape, pattern, and color. We structure our governments a bit different, too, we're predominantly a tribal people. Each person is a member of a tribe, which is rarely more than a hundred people. Each tribe elects a chief, who is a member of a tribe of tribes, which contains a hundred or so tribes. Each such tribe of tribes also elects a representative, who is a member of a geographically defined tribe, which elects a representative, and so on, until you reach the Council of Thirteen Stars, which is the highest tribe, and is the polity we joined under. Almost everything is resolved at the lowest level, and our population density's low enough people can just get up, walk off, and find food elsewhere if they don't like how their tribe's run. Disputes that involve multiple tribes or that otherwise can't be negotiated within each level get referred to higher groups."
"We have an average of about one to two kids per adult when we're not space-stressed, but we get antsy if there's too many people around and stop being able to reproduce, so our population fluctuates a bit around a set point. There's not really problems with fighting over space, though, like some species get? Probably because the amount of space we need to reproduce is higher than the amount we need to feed ourselves, so there's no pressing need to fight."
"Socially, we pretty much have chiefs, story-keepers, and everyone else, so there's no - set position in society. I wanted to be an explorer, so I became one."
"Geographically - hm, unlike this one. There's a variety of terrains, but it's effectively normal for a temperate rocky planet, I can look up the exact classification, there should be a briefing on it somewhere in the mess the scientists were trading..."
