Polar bears are stocky, with a long neck, relatively small head, short, rounded ears, and a short tail. The male, which is much larger than the female, weighs 410 to 720 kg (900 to 1,600 pounds). It grows to about 1.6 metres (5.3 feet) tall at the shoulder and 2.2-2.5 metres in length. The tail is 7-12 cm (3-5 inches) long. Polar bears live along shores and on sea ice in the icy cold Arctic. When sea ice forms over the ocean in cold weather, many polar bears, except pregnant females, head out onto the ice to hunt seals. Polar bears primarily eat seals. Polar bears often rest silently at a seal's breathing hole in the ice, waiting for a seal in the water to surface. A polar bear may also hunt by swimming beneath.

The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300-800 kg (660-1,760 lb).The species is sexually dimorphic, as adult females are much smaller. Polar bears roam the Arctic ice sheets and swim in that region's coastal waters. They are very strong swimmers, and their large front paws, which they use to paddle, are slightly webbed. Some. Polar Bear Physical Characteristics. The Polar Bear is an extremely large animal, with the males weighing up to 1,500 pounds. The females are only about 800 pounds when they are full grown. Males can be up to 10 feet in length with the females only about 8 feet long. The body of a Polar Bear is very different from that of other types of bears. Polar bears have a typical respiratory rate of 15 - 30 breaths per minute. However the breath rates go higher in warmer months. When the bear is asleep rates are only 5 breaths per minute. We have discussed polar bear anatomy such as respiratory system, urinary system, circulatory system, and Gastro-intestinal system.

The largest bear in the world and the Arctic's top predator, polar bears are a powerful symbol of the strength and endurance of the Arctic. The polar bear's Latin name, Ursus maritimus, means "sea bear." It's an apt name for this majestic species, which spends much of its life in, around, or on the ocean-predominantly on the sea ice. They could imagine they are a polar bear adult or cub, and write about their different experiences in the Arctic (e.g. hunting for food, digging/leaving their den, crossing water, the dangers they face, etc.). The children could also draw a picture of a polar bear with annotations explaining how the animal is adapted to life in the Arctic, i.e. Males weigh from 700 - 1,500 pounds, while females are only 300 - 600 pounds. They have huge front paws they use for swimming. Their skin is black and though their fur looks white, polar bears are now known to have transparent fur. This interesting adaptation allows light to be refracted on the clear strands giving it a white appearance. Polar Bear Walking - Polar Bear Anatomy. Young cubs are born with a light brown fur but within a few weeks the white color Polar Bears are well known for will emerge. In the summer they do have a yellowish color to them due to the lighting. Experts though believe the skin is black and the fur is clear because it doesn't have any pigment in it.

Adult females are usually 150-290 kg (330-650 lb). But some can be larger. Researchers in Canada estimated one male bear at 800 kg (1,700 lb)! Polar bears are also tall. Scientists usually measure their height at the shoulder when on all fours. Those heights are typically 1-1.5 m (3.3-5 ft) for adult polar bears. Ten polar bear facts. 1) Polar bears are found in the frozen wilds of the Arctic, in Canada, Alaska (US), Greenland, Russia and Norway. 2) These are seriously big bears, gang. Adult polar bears can measure over 2.5m long and weigh around 680kg. Their huge size and weight make them the largest living carnivores (meat eaters) on Earth! Love animals?
Polar bears are considered adults when they are old enough to mate. For females, this is ages 4-6, for males 6-10. By the time they reach adulthood, adult males normally weigh 350-600 kg (775-1,300 lb). Adult females usually weigh 150-295 kg (330-650 lb), though some can be larger. The diagram below illustrates how polar bears may have evolved from brown bears in response to the last ice age. Despite the fact that the bears now appear quite different physically (most notably in coat color), the genetic differences are very slight. Figure from: Crockford, S.J. 2006. Rhythms of Life:
Pictures Of A Polar Bear's Life Cycle
Collecting polar bear footprints to map family trees. Scientists from Sweden are using DNA in the environment to track Alaskan polar bears. The technique which uses DNA from traces of cells left. Montessori printables about polar bear anatomy, life cycle, andcharacteristics with 3-part cards, information cards, student booklets, and diagrams provide numerous benefits and uses for children. These resources promote hands-on learning, improve fine motor skills, enhance vocabulary and language development, and foster cognizance about the.
