A group of walruses is known as a herd. Walruses are highly social mammals, and they are often found in large herds. These mammals spend much of their life in aquatic environments.
Walruses have a widespread geographic range. Many walruses are located in the vicinity of the Arctic Circle. Atlantic walruses live from Greenland to the northeastern part of Canada along the coast, while Pacific walruses are found in the waters north of Russia and Alaska. These large mammals have unique features that permit them to exist in their extremely cold environments. Walruses have a great amount of fat for insulation, reaching a maximum weight in excess of 3,000 pounds, and they are also able to decrease their heartbeat.
