Glommer

The Glommer is a predator genetically engineered by the Klingons to hunt, kill and eat Tribbles. The first Glommer of its kind was stolen by Cyrano Jones[] in 2269 claiming it under the space salvage laws.

That same year, Captain James T. Kirk[] rescued Cyrano Jones from the Klingons. Cyrano brought the Glommer with him onto the USS Enterprise. After the Tribbles grew to be enormous, the Glommer did not seem so eager to eat them. (TAS: "More Tribbles, More Troubles")

The biology of the glommer is fairly simple on the bottom of the glommer a hole with many pulsating teeth witch goes straight into a holeless ring shaped stomoch were the leftovers are egected as a waste oil egected throgh the skin.The brain is slightly larger than tribbles allowing them to outsmart (but not by much) it's prey (tribbles) it is assumed the heart is bigger than a tribbles acounting for the glommers four legs. It might walk in a crab like style but assumingly in any derection.
