Chompacabras are a predatory species found only on Nexus. With a frighteningly inverse ferocity-to-size ratio, these diminutive, cuddly-looking omnivores represent an unpredictable menace to Dominion and Exile alike. Though chompacabras are small, they are able to take on creatures many times their size, using their expandable jaws to engulf their food in massive gulps that vanish impossibly down their tiny gullets. Fortunately for all life on Nexus - and perhaps all life in the galaxy - chompacabras are fairly rare. Most are solitary creatures that rarely interact with their own kind and have never been observed mating or rearing young. It is unknown how their life cycles begin or end, in fact. The mysterious chompacabras will no doubt continue to provide ample subject matter for scientists on Nexus for decades to come.
The chompacabras' digestive secret was only recently determined by xenobiologists. Chompacabras possess a hyperaccelerated digestive system that processes food into energy more quickly than it can be consumed - making their digestive tracts essentially bottomless. While this provides incredibly efficient nutrition for the chompacabra, it effectively eliminates whatever the chompacabra eats from existence forever.
