There are many types of bears. Some are large, some are small and some have fur while others don’t. When we think of bears without hair, most people think they would be very scary looking creatures. But when a bear loses its fur, it doesn’t become bald – it just looks naked! Did you know that the color and thickness of a bear’s coat depends on where it lives? For example, polar bears have white fur because they live in snow-covered areas with little sun exposure. However, if their skin is exposed to sunlight for prolonged periods (such as by losing their coat), both male and female bears can develop skin cancer or suffer from hypothermia due to increased water loss through their skin surface area which increases dramatically when there’s no longer any fur covering them up!

Like humans, bears have two layers of skin.

Like humans, bears have two layers of skin. The outer layer (epidermis) contains cells that produce new skin cells and protect the body from bacteria and viruses. The inner layer (dermis) contains fat cells which help to keep your bear warm in winter months.

The dermis also produces Melanin – a pigment found in many mammals including humans, dogs and cats as well as bears! Melanin controls how much ultraviolet radiation gets through our epidermis so it can help prevent sunburns when we’re out in the sunshine but sometimes too much exposure to UV rays can lead to skin cancers like melanoma or basal cell carcinoma if not protected properly with sunscreen!

The inner layer is called the dermis and the outer layer is called the epidermis.

The inner layer is called the dermis and the outer layer is called the epidermis. The dermis contains blood vessels, nerves, hair follicles and sweat glands. It also contains special cells called melanocytes that produce pigment (color) in your skin or fur.

The epidermis provides a barrier between you and your environment so that harmful substances cannot get into your body through it. It also helps regulate body temperature by absorbing heat when it’s hot out or releasing heat when it’s cold outside!

Both layers are made up of keratin–a tough protein found in hair, nails, horns and feathers as well as human skin–so even though bears don’t have any fur on their bodies they still have plenty going on underneath!

Bears have special glands that secrete oil which helps protect their skin.

Bears have special glands that secrete oil which helps protect their skin. The oil is called sebum and it’s secreted by sebaceous glands in the skin. Sebum is a mixture of fats, waxes and dead skin cells. The purpose of this natural moisturizer? To keep the bear’s fur from drying out or getting tangled up with each other when they’re sleeping together in winter hibernation caves (which can get pretty tight quarters).

The undercoat protects against cold weather by trapping air close to the body’s surface where it provides insulation against heat loss through conduction or convection throughout winter months when bears are hibernating together underground

The oil leaves a distinct scent on their fur that attracts mates during mating season.

The oil, which is secreted by a special gland and used to attract mates during mating season, also provides some protection against insects.

It’s not just for attracting mates: bears use their scent as a form of communication. They’ll mark territory with it and even rub up against objects to leave their mark on them–a behavior called “scratching.”

The oil also acts as a sunscreen and offers some protection against insect bites and bacteria.

The oils in the bear’s fur help it to retain water, which helps prevent dehydration. This is important since bears have large bodies with relatively small mouths, so they need to drink lots of water every day.

When bears don’t have any fur, they become vulnerable to water loss, sunburn and infections from biting insects such as ticks and flies.

The brown bear (Ursus arctos) is one of the largest terrestrial mammals on earth and can grow up to 1.8 meters (6 feet) tall at the shoulder. It lives throughout Europe Russia Asia North America Canada Alaska Yukon Territory Nunavut Northwest Territories Greenland Scandinavia Norway Sweden Finland Estonia Latvia Lithuania Belarus Ukraine Moldova Romania Bulgaria Macedonia Greece Albania Serbia Croatia Bosnia Herzegovina Montenegro Slovenia Hungary Slovakia Czech Republic Austria Liechtenstein Switzerland Germany Luxembourg Netherlands Belgium France Portugal Spain Italy Malta

If you see a bear without fur, it means that something is wrong with it.

If you see a bear without fur, it means that something is wrong with it. Bears are supposed to have thick layers of fur for protection from the cold and rain. If your bear doesn’t appear to have any fur at all, it may be sick or injured–or even dead!

Bears without fur can also be old and molting at this time of year; this means that their old outer layer will fall off so they can grow new one underneath it. This process takes several months (though some bears can go through several molting periods in their lifetime). During this time period, you shouldn’t approach or touch any animals because they might bite back if they feel threatened by humans getting too close to them

If you see a bear without fur, it means that something is wrong with it. If you find one in the wild, call your local wildlife agency or police department immediately so they can help get it back to safety before its health deteriorates any further!
