Marsican brown bear
The Marsican Brown Bear lives its life in isolation. With their existence dwindling, the 50 bears that remain in the Abruzzo National Park have characteristics that differ from their sibling subspecies. The Marsican Brown Bear, otherwise known as the Abruzzi Brown Bear, has a relatively calm temperament, with no aggression shown towards humans. In terms of size, the male Marsican Bear is larger than most of the brown bear subspecies, with a weight of around 217 kg (480 pounds), while the female is significantly smaller, at around 140 kg (310 pounds). These bears are known to be omnivorous in nature, mainly eating berries, while occasionally eating small animals such as chickens and other livestock. All of these traits the bear shows can likely be attributed to its existence in isolation. Baby Marsican bears tend to grow up fairly quickly.
