The Arctic hare is a heavyweight in the hare family. Adults weigh, on average, 4 to 5 kg (9 to 11 lb.), and they are longer than 70 cm (23 in.) from the nose to the tip of the tail. Females tend to be slightly bigger than males. Otherwise, males and females look so similar that they are difficult to tell apart at a distance. During the breeding season and the nursing period, males and females can be more easily identified by their behaviour.
