Kodiak bear
An average adult male measures in length, and stands tall at the shoulder. The largest recorded wild male weighed , and had a hind foot measurement of . A large male Kodiak bear stands up to tall at the shoulder, when it is standing on all four legs. When standing fully upright on its hind legs, a large male could reach a height of . The largest verified size for a captive Kodiak bear was for a specimen that lived at the Dakota Zoo in Bismarck, North Dakota. Nicknamed "Clyde," he weighed when he died in June 1987 at the age of 22. According to zoo director Terry Lincoln, Clyde probably weighed close to a year earlier. He still had a fat layer of when he died.
Spectacled bear
The spectacled bear is the only bear native to South America and is the largest land carnivoran on that part of the continent, although as little as 5% of its diet is composed of meat. South America's largest obligate carnivorous mammal is the jaguar ("Panthera onca"). Among South America's extant, native land animals, only the Baird's tapir ("Tapirus bairdii"), South American tapir ("T. terrestris") and mountain tapir ("T. pinchaque") are heavier than this species. The spectacled bear is a mid-sized species of bear. Overall, its fur is blackish in color, though bears may vary from jet black to dark brown and to even a reddish hue. The species typically has distinctive beige or ginger-coloured markings across its face and upper chest, though not all spectacled bears have "spectacle" markings. The pattern and extent of pale markings are slightly different on each individual bear, and bears can be readily distinguished by this. Males are a third larger than females in dimensions and sometimes twice their weight. Males can weigh from , and females can weigh from . Head-and-body length can range from , though mature males do not measure less than . On average males weigh about and females average about , thus it rivals the polar bear for the most sexually dimorphic modern bear. A male in captivity that was considered obese weighed . The tail is a mere in length, and the shoulder height is from . Compared to other living bears, this species has a more rounded face with a relatively short and broad snout. In some extinct species of the Tremarctinae subfamily, this facial structure has been thought to be an adaptation to a largely carnivorous diet, despite the modern spectacled bears' herbivorous dietary preferences.
