What, and Rustacean doesn't? When we Uplift our Cetacean friends, is this sort of awkward appropriation really how you want to meet the newly-conscious masters of 3/4s of the planet?
I parse 'Rustacean' as appropriating crustaceans, not cetaceans. I'm rather less worried about annoying them, because i eat enough prawn toast that i'm already on their shitlist.
