Arctic Tyrannosaurus

The Arctic Tyrannosaurus is a breed of Tyrannosaurus rex that has been adapted to an arctic environment, likely through purposeful genetic manipulation as opposed to any natural process. Its primarily-white coloration harkens back to the Indominus rex, a hybrid created for Jurassic World before it destroyed the park.

It is possible it was developed with help from Dr. Henry Wu for inGen's military applications program.

Description and Statistics
As far as size goes, the Arctic Tyrannosaurus is considered to be on par with regular t. rexes in terms of overall size statistics such as length, height, and weight. Given its requiring DNA from creatures able to survive in arctic conditions, it may have blubber in its body or may instead come to hibernate during the cold winter months like a wood frog.

Like other JP-developed t. rexes, they are believed to display some level of sexual dimorphism, with males having more prominent lacrimal ridges than females. Males also have a tendency to have visible facial scarring (possibly due to battles over territory with other T. rex and carnivores or mates). Females may or may not be brown in color, but are considered to most likely be somewhat larger than other breeds. Males are perhaps slightly smaller than females and are a mostly-white color, with splotches of varying shades of blue across its muzzle and dorsal section. A head crest displays a vibrant orange. They also have a large throat pouch that females seem to lack.
