EMC ships are all named after dangerous animals of Earth. I've served eleven years on the EMC Pufferfish.

[Dangerous animals selected by the Krakau, who didn't have living, sentient humans to check the specifics of naming conventions.]

The Krakau also give themselves 'human names' based on the names of human music. It's hard for us to remember or say their names. And cured humans name ourselves for famous or important humans.
