In 2019, the New Scientist LIFE magazine wrote about the superpowers of reindeers. Do they really have superpowers?

The Reindeer, or Caribou, is a large mammal in the Cervidae family of deers. Nearly 5 million Reindeers live in the freezing climate of the Arctic, from Alaska to Siberia and Greenland, where there are more periods of night-time darkness than day-time light. 

Genetic scientists know that Reindeers can change the colour of their eyes from gold in summer to blue in winter. They are also working on the Ruminant Genome Project to study Reindeer genes – their DNA – to compare their genes to human genes and other animals, especially other ruminants. Ruminants are animals that chew their cud, such as deer, cattle, goats, sheep, giraffes, gazelles, and antelopes.
