Eurasian Brown Bear Physical Description

The wondrous Eurasian Brown Bear immediately draws the attention of anyone fortunate enough to encounter it in the wild. Certainly, it’s a beautiful mammal, of course. Yet it principally garners attention due to the sheer size that the species remains capable of reaching in some cases.

It additionally follows a pattern that’s well established by its many kindred found around the world. That’s in the fact that it displays a certain degree of the physiological characteristic of sexual dimorphism. In its specific case, this natural trait manifests itself mainly in physical measurements.

More exactly, males of the species typically attain a larger size than their female counterparts. This extends to both weight and length of body. The males sometimes reach a total length equaling up to 8.2 ft (2.5 m). Female specimens, however, usually reach somewhat shorter lengths than this.

Weights also naturally differ markedly between the sexes, given these facts. Males typically range from around 550 – 660 lb (250 – 300 kg). A few mass as much as 1,060 lb (481 kg), though. Meanwhile, the females of the animal generally range in mass from 331 – 550 lb (150 – 250 kg).

Both genders of the stunning Eurasian Brown Bear display the same general pattern of coloring. That consists of brown fur that covers the entirety of the body, save for the soles of the feet. The shades of this coat vary between specimens, ranging from yellow-brown to almost black.

The relatively largely head also develops as highly rounded in shape. The ears develop as comparatively small, and rounded as well. Its powerful jaw holds 42 extremely sharp, predatory teeth. The mighty animal also possesses strong, sharp claws that reach up to 3.9 in (10 cm) in length.

Eurasian Brown Bear Distribution, Habitat, and Ecology

The captivating Eurasian Brown Bear evolved as endemic to a large portion of the surface of the globe, relatively speaking. Given its name, the location of that zone of habitation comes as no surprise. As alluded to, the animal inhabits the majority of the continents of Europe and Asia.

Within that greater range, however, its current presence appears to be sporadic. The largest known concentration presently exists in Russia. Other groupings appear in such countries as Greece, Serbia, Poland, Turkey, Albania, and along the border between France and Spain, among others.

Nature and evolution did provide this mammalian marvel with an impressive adpatability regarding its choice of habitat. That’s so far served it well in its struggle to survive. Generally speaking, though, it often lives in regions composed of wetlands, sparsely vegetated areas, and grasslands.

Yet perhaps its most highly favored type of environment is even more specific. That’s due to the fact that the largest percentage of individuals choose to make their home within areas of mountain woodlands. It typically does tend to avoid the highest altitudes however, due to the scarcity of food.

Intriguingly, the dietary habits of the Eurasian Brown Bear today aren’t what they once were. In the past, studies showed that meat comprised about 80% of its diet. Today, though, that only forms about 10-15% of it. The notable change likely occurred due to reduced number of prey animals.

Being technically omnivorous, the large mammal mainly feeds on large quantities of roots, seeds, insects, fruit, and fish. When it does eat meat, the powerful predator seems to favor sheep. Yet it also feeds opportunistically, having no qualms about eating carrion when it comes across it.
