Black Bear Vs Polar Bear

As members of the mammal family, the giant panda and the polar bear share many of the same physical characteristics. On the other hand their appearances set them apart from one another in many ways. To start with pandas and polar bears are well alike and different in many ways. When being born pandas are about 15-17 centimeters long. Polar bears on the other hand though are born about 30-35 centimeters long. Pandas over the time grow and are white with big black spots around their body.

The bear have evolved along time ago and now there is only eight species existing. They evolved from early canids during the late Oligocene and early Miocene, about 25 million years ago. The earliest ancestors where the Dormaalocyon Latouri. An intermediate ancestor was the short faced bear, very similar to the modern day bear. It lived through the pleistocene period. It grew to thirteen feet long and was a herbivore. The ancestors to the modern day bears lived in the same climate and ate the same things. The modern bear contrast from the ancestor because the ancestor was more skinny and was smaller, and it was more cat like. The eight species of bear that still exist. They are the Polar bear, Brown bear, American black bear, Asian

Outside the british Columbia only about one in a million black bears are white. One of these bears,a subadult male lived near Orr, minnesota in 1996.Hair samples showed him to be genetically different from white Kermode bears.

Prior to the late 1900s they roamed throughout Florida, over 53,000 square miles of land. From the Panhandle to the Keys, to the southern edges of our neighboring states. At that time an estimated twelve to twenty thousand black bears roamed throughout Florida.

In September, the bears will eat up to twenty-thousand calories to build fat layers for winter. Which is ten times a normal human's daily intake. (animals) Bears spend most of the year pursuing a patchwork of habitats throughout the year, feeding on vegetation, insects, and other more reliable, though lower calorie food sources. These food sources include nuts, carcasses, plants, berries. Plants make up the majority of a bear’s incredible diet.

Currently, most Louisiana black bears live in St. Mary and Iberia in south Louisiana, Tensas, and West Carroll Parishes in northeast Louisiana and Pointe Coupee in central Louisiana.(figure 4) However, male bears often wander long distances, so the sighting of Louisiana black bears are now common all over Louisiana, and west and southern Mississippi.

Black bears are the smallest North American bears however; they are the largest land mammal in New Jersey. Black bears evolved in thick forest and live in mixed hardwood forests, dense swamps and forested wetlands. They naturally like to eat fresh leaves, berries, fruits, nuts, roots, insects, bird eggs and small mammals. Black bears are generally solitary animals, with the exception of a sow and her cubs. They tend to be crepuscular, meaning they are most active shortly before sunrise and again after sunset. Black bears are typically not aggressive and tend to be wary of humans.

The black bear, ursus americanus, roams in different places in America including Texas. Its North America the black bears habitat ranges from Mexico all the way to Canada. In the state of Texas, the black bear is under threatened status, it also has the same status under the United States (Texas Parks and Wildlife Department). According to the Texas Parks Wildlife Department (2016) in the state of Texas they are usually found in the Western area in the Trans Pecos ecoregion. The Texas Parks and Wildlife Department (2016) has reported that there have been recent sightings of the Louisiana Black Bear in the Eastern part of Texas, where they used to have a strong population. This comes as surprising since the Louisiana Black Bear has an endangered status in the United States, as well as in the state of Texas. Even though the black bear species population in Texas is not as strong as it used to be in the past, many efforts are being done to recolonize the black bear in the South Western region of Texas by, studying their habitat as well as their eating habits, checking the DNA of the bears already in the area to see their genetic structures, regulating protection policies for black bears, and educating the people on the species.

and Canada offer, black bears can live in both coniferous and deciduous forests, as well as the open alpine habitats. Basically anywhere near a river or some water source, has plenty of trees, and are able to find food. Black bears usually forage alone, even as young cubs. They will stick together with their mother if there is an abundance of food in one are.

Black bears are omnivorous, meaning they eat both plants and animals. One way to distinguish the pawprint is that of a black bear is to check for five toes with claws, a pointed heel in the back, and a rounded front. The size of a black bear ranges from one hundred twenty-five to five hundred

Lifespan: Black bears can live up to 30 years in the wild but most only live around 10 years because of circumstances involving humans. Over 90% of young bear deaths are the results of gunshots, traps, vehicles and various other human interactions.

The favorite food of the polar bear is the ringed seal, however if hungry enough, they will eat other breeds of seals including bearded, harp, hooded and harbor. Polar bears will also eat beluga whales and walrus (Field Guide 2002). At times, they will even eat eggs, crabs and kelp (Milius 1994). The polar bear is strong enough to lift a beluga whale, several times its own weight, out of the water for a meal

After reading both of the stories I found that both the animals the Polar Bear and the Angler fish are Carnivores. They both have a harsh envirorment.Since they are both Carnivores thet dont have to good of a food supply, like if they live in a grassey green place since the only eat meat . They adapted to those harsh envirorments very well by,the anglerfish having to atract fish with the light on there head.Allthough the Polar Bear lives in -50 degrees.But the polar bear has black skin that absorbes the heat and 4 inches of blubber to go with that , the Polar Bear has to lay down in the snow to cool off. The Polar Bear has long strong legs and huge curved claws are especially adapted for striking and killing their prey. Now you know that theese

The polar bear lives up in the Arctic region where global warming and climate change are melting the ice caps that the bears thrive on. They use the ice as a platform from hunting and rest. The random pocket holes in the ice, where the seals pop up at, is where the polar bear catches its prey. With this reduction of ice, “the abundance of seals, and increases the amount of energy and time needed for hunting, leaving less energy for reproduction” (Endangered Species and Habitats).

Bear is a true carnivore, but if not prevented the black bear could be a huge problem to humans.
