Wow I'm super late, but is it cool if Data scans these delightful creatures with his tricorder?
It would show some basic data - their vitals, genetic makeup of the species, the basis of their biology, brain activity, that kind of thing. Of course, seeing as they're not any species that Starfleet has encountered, the tricorder won't have some information and some of these readings could be totally inconclusive.
The tricorder also has a universal translator, which he would also try to utilize, but... that will obviously fail. :D
