A beast from America
The elk is the largest species of deer, with antlers on adult males weighing in excess of 25 kg. Elks are good swimmers, and are happy diving several metres below the surface of a lake if there is a chance of finding edible aquatic plants. Elks are unable to sweat, so they prefer resting in the shade or cooling themselves in a lake on hot summer days. Their long legs enable them to easily negotiate areas with 60-70 cm of snow. They can run at up to 55 km/h, but deep snow makes them vulnerable to wolves and other predators.
