Bears SVG includes the largest of the modern terrestrial predators. Most taxonomists believe that there are currently eight species of bears on Earth (they are divided into many different subspecies), belonging to three different branches.
Features of the Bears SVG
Bears are found on all continents except Africa, Australia and Antarctica. Three species of bears – spectacle, lip and Malay – live in the tropics, but the centre of origin of the bear family is in the Northern Hemisphere. Long ago, a brown bear was also seen in the Atlas Mountains in northwest Africa.
Bears are mainly inhabitants of different types of forests and rare forests. One species, the polar bear, inhabits the Arctic deserts and ice.
The most probable ancestors of modern bears were small predators who lived 25 million years ago (subfamily Agriotheriinae). The oldest representative of this group, Ursavus elmensis, had a long tail and looked like a raccoon, but the animals of a later period already resembled modern bears in size and appearance. This group started three modern subfamilies. The big panda separated from the common trunk first, then the real bears (Ursus and his parents) and spectacle bears (Tremarctos) separated.
Depending on the species, the length of the predator’s body can vary from 1 to 3 meters, the weight of individual polar bears and brown bears can reach up to 1000 kg. Males are much larger than females.
Bears have heavy, clumsy folds. In order to maintain a large mass, their hind limbs are stopping (when walking, the entire sole is pressed against the ground). It also allows them to climb freely and stand on their hind legs. The structure of the front paws varies from one species of bear to another, from staggering bears to semi-finger bears (the back of the foot is partially raised above the ground). All the species have five fingers on each leg, equipped with curved and loose claws.
The skull of bears is massive, larger than that of other predators; the facial part of bears is of medium length or shortened (especially of spectacle bears). Wide root teeth with flat chewing surfaces and rounded fangs are well suited for crushing and rubbing plant foods. Polar bears are exceptionally carnivorous animals, so their teeth are sharper. Depending on the species, the bears’ teeth are 40-42.
Bears’ fur is thick, long; the coloring is usually dark, monotonous, brown to black (exceptionally white or contrast-two-colored), sometimes with a light pattern on the head and chest. Tail is very short; ears are small, rounded; lips are big and very mobile.
Polar Bears SVG and most of the brown New World do not climb trees, only the European brown and all other species climb trees where they feed or sleep, but most of the time they still prefer to spend on the ground. For tree-climbing predators, bears have surprising features – they have too short tails and no facial vibrices.
Most bear species are non-specialized omnivorous animals that feed on berries, nuts, shoots, rhizomes and leaves, as well as meat, fish and insects. They have excellent sense of smell, color vision and good memory, which allows them to remember places rich in food. It should be noted that the vegetable food of bears is not digested very well, because in their gastrointestinal tract there are no symbiotic microorganisms capable of decomposing fiber (these bacteria are present in the stomach of ruminants). Therefore, plant fibers and berries are excreted almost undigested.
