Snow leopards, or Uncia uncia, are found in mountainous regions throughout Central Asia. These large felines are identified by their white fur and black spots. Snow leopards possess fur on the bottom of their paws, which prevents their paws from being damaged by their rocky habitat. In order to find mates, snow leopards create an odor and claw markings on boulders.
Found in mountains in Alaska and Canada, mountain goats, or Oreamnos americanus, have shaggy white fur and grow up to 5 feet (1.5m) in length, when fully mature. Mountain goats' white fur help these mammals blend in with their snowy environment. Primary dietary items include wild grass, woody plants and moss.
Okapis, or Okapia johnstoni, are found in the rainforest of Africa, particularly forests in Uganda and the Democratic Republic of the Congo. These mammals have elongated necks and large hooves. Okapis manage to stay camouflaged in the forest with their dark brown fur, which has black and white stripes on its hind legs.
Found in western Africa jungles, yellow-backed duikers, or Cephalophus sylvicultor, receive their name from the yellow patch of fur on their backs. These mammals are difficult to find, since they are prone to hide in underbrush when they sense danger. Adult yellow-backed duikers grow up to 5 feet (1.5m) in length.
According to Sea World, the blue whale, or Balaenoptera musculus, is the largest discovered animal on earth and perhaps the largest animal in the history of the world. As adults, blue whales reach lengths of 70 to 110 feet (21 to 34m). These marine mammals are usually found in the northern Pacific Ocean, near Alaska in the U.S. and Russia.
The Florida manatee, or Trichechus manatus latirostris, lives in the waters of the Southeast United States; sightings are usually the Gulf of Mexico and Atlantic Ocean near Florida. As herbivorous creatures, Florida manatees' diets consist of seagrass and algae; these animals eat nearly 8 percent of the their body weight on a daily basis.
Ring-tailed lemurs, or Lemur catta, are only found on the island of Madagascar. This lemur is identified from other lemur species by the black and white rings around its tail. Although they are primarily quadrupeds, ring-tailed lemurs are able to walk on two legs if necessary. When walking on narrow branches, these mammals use their tails for balance.
Found in Southeast Asia, white-cheeked gibbons, or Nomascus leucogenys, live in the upper canopies of the region's rainforests. According to the National Zoo, it is a rare occurrence to see these arboreal mammals on the ground when they are in the wild. White-cheeked gibbons release a loud howling noise when calling for their mates are defending themselves.
