"Caribou is the given name of wild reindeer in North America, and they are primarily found in Alaska and Canada. Interestingly, they have never been domesticated despite their importance in native culture. They have the longest migrations of all known land animals with yearly migrations of large herds covering several thousand kilometers. Like the Eurasian reindeer, both male and female caribous grow antlers. Adults measure between 0.85 m and 1.50 m at the shoulder. Females weigh up to 120.00 kg while males can exceed 180.00 kg . Males and females live together in small groups that merge into massive herds when they migrate."
