Bardakian pronghorn moose
From Memory Alpha, the free Star Trek reference
The Bardakian pronghorn moose is a large terrestrial animal notable primarily for its loud vocalizations, which some consider unpleasant.
Omag once compared Klingon opera, in particular Aktuh and Maylota, to the sound of a Bardakian pronghorn moose. (TNG: "Unification II")
