Desert Scraptors are the physically the same as their counterparts, but with more clawed feet, yellow eyes and desert camouflage; other than their coloration and the fact that they have horns, Desert Scraptors are just like regular ones. One thing that can be considered a curiosity / mystery is the appearance of a strange scraptor in season 4 episode 6:Gearwigs. What is intriguing about this scraptor is the fact that although he did not have horns like desert scraptors, he possessed the same color / camouflage, same paw type / shape, same eye color and same desert scraptor mouth. Was it a variation of desert scraptor or a new subspecies of common scraptor ? One explanation is that the animation intended to make it a Desert Scraptor, but forgot to add horns. Naturally, the computer filled in the gap.
They are obviously smarter than regular Scraptors, since they build traps that are advanced, at least for a Scraptor; they also dig complex tunnels underground. Also, they have an Alpha, the leader of the pack. One of their most well-known tactics is placing volcanic ore in deserted areas and waiting for any unsuspecting creatures to move by, and when this happens, through some sort of motion-detection, perhaps sensing vibrations, the pack attacks whoever or whatever is nearby. http://img.rtve.es/v/3630695?w=400&preview=1465586505297.JPG
