Humpback Xatapur

The humpback xatapur replaced it's ancestor, the smaller xatakpa, in the deserts of Barlowe, where the 'hump' served to improve water and energy storage. The humpback's armour was an adaptation for defense and as a source of vital water. The dew collecting on the ridges is licked up in the morning by the herd, which tended to be smaller than it's ancestors. The leathery flesh around vital areas protect the eyes and nostrils from sand storms. Due to the high adaptation shown by the humpbacks, they were relegated to the deserts and high deserts of the region, and no longer ventured into colder areas or near the ocean. However, stronger teeth and longer survival allows them to live in the high regions where their predecessors couldn't survive. Increased size meant that humpbacks consumed significantly larger amounts of flora matter, and thus the population of humpbacks was no where as high as the xatakpa populations they evolved from.
