Elk are a species of deer found in North America and eastern Asia. They are found mainly in forests, and eat a mixed diet of grasses and leaves. In their natural range, their predators include wolves, cougars, brown bears, tigers and leopards.
During the Seven Years' War, the Assassin-turned-Templar Shay Cormac hunted both male and female elk. When skinned, a male elk carcass would yield an elk pelt, elk meat and elk antlers, while a female carcass would provide him an elk heart. 
During his time in the colonies, the Grand Master Haytham Kenway, also hunted elk, though he was not able to skin them. Haytham's son, Ratonhnhaké:ton, hunted elk and sold their pelts at general stores. After joining the New England Hunting Society, Ratonhnhaké:ton was informed of an overly-aggressive elk. He successfully tracked down and killed "King Edward the Elk".
