Appearance
The arctic reefback's appearance seems very similar to the regular reefback. However, there are some key differences. Firstly, the large crest-like structure is something that the average reefback doesn't have, and has an unknown purpuse. It also seems to be substantially smaller, as the alien penguins on top don' t seem to be that much bigger (possibility that penguins might be huge). Thirdly, it seems to mimic the appearance of an iceberg, which could be used as a form of camouflage.
