You can have several names from the ones the scientists call it to nicknames given by the personel who see them (or who are attacked by them)

The caverns are otherwise dark so good ole bioluminescence can be used again along with other lifeforms in a whole ecosystem  (fungus as the base level) in the underground area

I dont know if you should tap into the whole UFO thing from the 50s  (could explain how theos living things got there originally as the lifeless moon is kindof a hard environment for them to form on their own  (though within realm of possibility that bacteria from earth escaping with atmosphere into space could have reached the moon )
