Homo Penguinis

Although it sounds sexual, it is simply the term used to name a species of humanoids who evolved from penguins. They lived in the Delta Quadrant, tried to take Larkin as their god, but refused her once her crewmates crashed a runabout into their leader ("Leader of the Flock" [VEX]), and then were promptly transported to the Alpha Quadrant, where Ardek tried to use them to capture and dominate the human Larkin, using that Larkin as bait to draw in the android Larkin. They finally saw through his ruse and ran away ("BOOK 4: Birds Of A Feather" [VEX]).
