There are estimated to be 400 million dogs in the world. A wolf is a carnivorous mammal. When hunting, they often howl as a signal to other wolves in their pack. Females have four to six pups each spring. In many areas, the wolves are nearly gone because they were killed by humans.
They can weigh up to 350 pounds. They are not able to walk on hind legs. There are only about 1000 left in the wild because of their habitat being destroyed. They spend 14 hours a day eating, which is abut 50 -60 pounds of bamboo in one day. The next oldest bear that evolved was from the Subfamily Tremaratinae, the family of the Adean (or Spectacled Bear).
The gray wolf also called the timber wolf, is the largest of about 41 wild species within the dog family They range in size from 26" to 38" shoulder height, 39" to 80" in length (tip of nose to end of tail), and vary in weight from 57 to 130 pounds. Their coats may vary in color from grey to brown, from white to jet black. They usually hunt at night and feed primarily on large hoofed mammals such as deer, caribou, elk, and moose, but sometimes eat berries, birds, beaver, fish, and insects. Animals that they kill are usually young, old, or otherwise weaker members of their populations because they are easiest to capture. Most pursuits of prey range in length from 110 yds.
Northern forests offer the lowest human density of any tiger habitat, and the most complete ecosystem. The vast woodlands also allow tigers far more room to roam, as Russia's timber industry is currently less extensive than that of many other countries. Tigers are the largest of all wild cats and are renowned for their power and strength. There were once eight tiger subspecies, but three became extinct during the 20th century. Over the last hundred years, hunting and forest destruction have reduced overall tiger populations from hundreds of thousands to perhaps 3,000 to 5,000.
Their natural habitats are old-growth forests and these can be found in places that range from northern California, all the way to British Columbia, Canada. There are only around 2360 Northern Spotted Owls left in the wild. The owls do not migrate or move from their territories unless there is a disturbance in their habitat. An example of a disturbance would be if a lumber company wanted to tear down the forests for the wood.The owls would be forced to leave because those trees are not only home to the owls, but they are also home to the owl’s food source. The Northern Spotted Owls are very territorial.
In the “Little Red Riding Hood” tales and variants, the forest is always the setting in which the girl comes in contact with the wolf. She is put into a situation in which she is not used to, and she must fight to survive. In “The Company of Wolves” it is explained to us that wolves are very clever. They lurk in the forest and prey on those that are weaker than themselves. Aside from the fact that wolves are conniving beasts, the narrator in this story warns us that the worst situation is to run into a wolf that is “more than he seems” (Carter 111).
Polar bears Polar bears (Ursus Maritimus), apart from being found in zoos, polar bears are omnivorous mammals native to only the Arctic Circle. The polar bear is the largest terrestrial carnivore, being more than twice the size of a Siberian tiger. Adult males weigh 350–680 kg (770–1500 lbs) and measure 2.4–3 m (7.9–9.8 ft) in length. Adult females are roughly half the size of males and normally weigh 150–249 kg (330–550 lb), measuring 1.8–2.4 metres (5.9–7.9 ft) in length. When pregnant, however, they can weigh as much as 499 kg (1,100 lb).
But in July 2011, the park experienced its first bear-related fatality since 1986 when a grizzly sow defending her cubs attacked two hikers on the Wapiti Lake Trail. And not long after, Yellowstone wildlife officials had to kill a different grizzly bear when it acted aggressively toward park visitors during several different incidents. The potential for bear encounters is also increasing. More people are out on trails and development along the wildland-urban interface has infringed on bear habitat. And changing patterns in bear behavior are bringing the animals closer to populated areas than ever before.
The Ursus maritimus most commonly known as the Polar Bear, ranges from seven to nine feet long, making them on of the largest mammals on earth. On average a male Polar Bear can weigh over a ton while the females are only one third of the weight sitting on 300-550 pounds. (Roach. J 2007) These carnivorous animals have a diet consisting of seals however they have been known to eat walruses, carcasses of whale and in some cases were they are desperate enough they will eat whatever meat they can find. (Endangered Species List) The Polar Bears live in an Arctic ecosystem as they rely on sea ice for their habitats where they can live twenty to thirty years.
They are rare and endangered and live in some of the most extreme high altitude and cold climate on It is a sad fact that the biggest threat to snow leopards are humans. Humans have hunted them for their fur and their bones; fur to wear as coats and hats, and bones to be used in traditional medicines. They have also destroyed snow leopard habitat and food sources by killing the prey animals they need to feed on. When the natural wild prey animals are not available snow leopards will often kill and eat domestic livestock like sheep and goats belonging to villagers they share the mountains with. The second reason why snow leopards are endangered is the global warming .
