Polar Glasseater

The polar glasseater split from its ancestor the glasseater. It has moved to Drake Polar Scrub and Drake Tundra. There are only microbe glass flora in Drake Polar Scrub so most of the population is in Drake Tundra. However those in the polar scrub still can get to the micro glass flora by eating the cyan colored snow. Their stomachs have developed a tolerance for eating snow. However they cannot to it too much or risk lowering their core temperature. Eating snow also means they do not have to find a source of water as often. Their bodies have become more stout to reduce heat loss. Their "eye-ears" and "ear-nostrils" have gotten smaller as well as their legs have become shorter. Their hoofs have becomes spades so they can better walk on the ice and snow. And their back "tail-foot" now walks on its toes so the bottom of their feet do not touch the ground. Like their ancestor they have very strong grinding teeth that can break down the outer covering of the glass flora. Their chin-spike can uproot them so they can chew them whole. They also must swallow grinding stones in their newly evolved gizzard. This helps mash up the parts they did not crush with their teeth. Their mouth and digestive tract is very tough in order not to get cut by the glass flora shards and their digestive juices are even stronger to help in digestion. They hear using their "eye-ears" and "ear-nostrils". They communicate with bellowing calls and travel in herds of 30 to 50 members. The males fight over females by jousting with their chin-spikes. Males chin-spikes are much larger than females. When battling they will rear up on their tail and back legs and then come crashing down on their other male's head. This can sometimes result in puncture wounds or even death. They no longer build burrows but build mound nests out of rocks and dirt for their hard-shelled eggs. During incubation females will tend to the mound to make sure it is the right temperature by taking dirt either on or off the mound. They must do this in the summer when the ground is not frozen. Once hatched the female will protect the nest while the male goes to find food for his mate and offspring. They lay around 3 to 4 eggs at a time.
