The Akritirian chaka emu was a marsupial hybrid animal lifeform from the galaxy's Delta Quadrant, in Akritirian space.
History and specifics[]
Should one of these creatures die before it is fifty-three, then the animal's brains turn into beans. This was discovered by the great chef Kok LaKok "The Kok" LaPokkok. As a food, this was called mool. (ST reference: Star Trek Cookbook)
