dolphin

When global famine sent humans looking for new food sources on old Earth, dolphins shocked humanity by fleeing the planet in aquaships they'd built in secret on the ocean floor. Dolphins subsequently colonized the oceans of numerous worlds, ultimately becoming the catalysts for the foundation of the Confed. Their smarmy, condescending attitudes and obsessive tidiness, not to mention the whole can't-live-more-than-a-few-minutes-out-of-water thing, make dolphins complete buzz-kills at parties.
