Blorthogs are quadrupedal, terrestrial creatures. Their large ears indicate an excellent ability to hear, while their large eyes may indicate excellent eyesight, as well. Oddly, the spiked rump of the creature lead one to consider a possible genetic connection to the Boarmards of the planet Bilzac, and in that aspect, possibly the local Aawkwards of the same world. These rump spikes can be fired at any potential predators who might give chase to them.
They may have gone extinct.
