Crocodiles, A Fighter from Swamp
Crocodiles are large aquatic reptiles that live throughout the tropics in Africa, Asia, Americas and Australia. Crocodiles tend to congregate in freshwater habitats like rivers, lakes, wetlands and sometimes in brackish water. They feed mostly on vertebrates like fish, reptiles, and mammals, sometimes on invertebrates like mollusks and crustaceans, depending on species. They are an ancient lineage, and are believed to have changed little since the time of the dinosaurs. They are believed to be 200 million years old whereas dinosaurs became extinct 65 million years ago; crocodiles survived great extinction events.Crocodiles are ambush hunters, waiting for fish or land animals to come close, then rushing out to attack. Crocodiles eat fish, birds, mammals and occasionally smaller crocodiles.
Komodo, A Dinosaur from Komodo Island
Komodo dragon are protected under Indonesian law, and a national park, Komodo National Park, was founded to aid protection efforts.
Deer, Most Hunted Animal by Hunters
Deer live in a variety of biomes ranging from tundra to the tropical rainforest. While often associated with forests, many deer are ecotone species that live in transitional areas between forests and thickets (for cover) and prairie and savanna (open space). The majority of large deer species inhabit temperate mixed deciduous forest, mountain mixed coniferous forest, tropical seasonal/dry forest, and savanna habitats around the world. Clearing open areas within forests to some extent may actually benefit deer populations by exposing the understory and allowing the types of grasses, weeds, and herbs to grow that deer like to eat.
Deer weights generally range from 40 to 200 kilograms. They generally have lithe, compact bodies and long, powerful legs suited for rugged woodland terrain. Deer are also excellent jumpers and swimmers. Deer are ruminants, or cud-chewers, and have a four-chambered stomach. The teeth of deer are adapted to feeding on vegetation, and like other ruminants, they lack upper incisors, instead having a tough pad at the front of their upper jaw.
Orangutan, Protected by Law
The most recent estimate for the Sumatran Orangutan is around 7,300 individuals in the wild. Orangutan habitat destruction due to logging, mining and forest fires, as well as fragmentation by roads, has been increasing rapidly in the last decade.
Honey Bear, Character of Winnie The Pooh
The Sun Bear or Honey Bear, is a bear found primarily in the tropical rainforests of Southeast Asia.
The Sun Bear stands approximately 1.2 m in length, making it the smallest member in the bear family. Unlike other bears, the Sun Bear's fur is short and sleek. This adaptation is probably due to the lowland climates it inhabits. Dark black or brown-black fur covers its body, except on the chest, where there is a pale orange-yellow marking in the shape of a horseshoe. Similar colored fur can be found around the muzzle and the eyes. These distinctive markings give the Sun Bear its name.
The diet of the Sun Bear varies widely and includes small vertebrates, such as lizards, birds, and other mammals, in addition to fruits, eggs, termites, the young tips of palm trees, nests of bees, berries, sprouts, insects, roots, cocoa, and coconuts. Its powerful jaws can crack open nuts. Much of the Sun Bear's food must be detected using its keen sense of smell, as its sight is poor.
Snakes, A Human Enemy
The skin of a snake is covered in scales. Contrary to the popular notion of snakes being slimy because of possible confusion of snakes with worms, snakeskin has a smooth, dry texture. Most snakes use specialized belly scales to travel, gripping surfaces.
All snakes are strictly carnivorous, eating small animals including lizards, other snakes, small mammals, birds, eggs, fish, snails or insects. Because snakes cannot bite or tear their food to pieces, a snake must swallow its prey whole. The body size of a snake has a major influence on its eating habits.
Zebra, A Unique White and Black Stripes
Like horses, zebras walk, trot, canter and gallop. They are generally slower than horses but their great stamina helps them outpace predators. When chased, a zebra will zig-zag from side to side making it more difficult for the predator. When cornered the zebra will rear up and kick or bite its attacker.
Giraffe, The Tallest Land Animal
Elephants, Symbol of Wisdom
Elephants are a symbol of wisdom in Asian cultures and are famed for their memory and intelligence
The Sumatran Elephant is found only on Sumatra. Population estimates for this group range from 2,100 to 3,000 individuals. It is very light grey in colour and has less depigmentation than the other Asians, with pink spots only on the ears. Mature Sumatrans will usually only measure 1.7–2.6 m at the shoulder and weigh less than 3,000 kg
One thing that interesting from elephants are their trunk which is used for drinking. Elephants suck water up into the trunk up to 14 litres at a time and then blow it into their mouth. Elephants also suck up water to spray on their body during bathing. Beside that, familiar elephants will greet each other by entwining their trunks, much like a handshake.
Kangoroo, Maskot of Australia
The average life expectancy of a kangaroo is about 4–6 years.
Kangaroos have developed a number of adaptations to a dry, infertile continent and highly variable climate.
The kangaroo has been historically a source of food for indigenous Australians. Kangaroo meat is high in protein and low in fat (about 2%). Kangaroo meat has a very high concentration of conjugated linoleic acid (CLA) when compared with other foods. CLA has been attributed with a wide range of health benefits including anti-carcinogenic and anti-diabetes properties, in addition to reducing obesity and atherosclerosis.
Hippo, Character of Gloria in Madagaskar
The hippopotamus is semi-aquatic, inhabiting rivers and lakes. Their specific gravity allows them to sink and walk or run along the bottom of a river. During the day they remain cool by staying in the water or mud; reproduction and childbirth both occur in water. They emerge at dusk to graze on grass. While hippopotamuses rest near each other in the water, grazing is a solitary activity and hippos are not territorial on land.
Iguana, A Lizard from Tropic Areas
Iguanas have excellent vision and are able to see shapes, shadows, colors and movement at long distances. Iguanas use their eyes to navigate through crowded forests, as well as for finding food. They use visual signals to communicate with other members of the same species. Iguanas are often hard to spot, as they tend to blend into their surroundings. The color green helps as a mode of hiding from larger predators.
Jaguar, A Big Cat from America
Like all cats, the jaguar is an obligate carnivore, feeding only on meat. It is an opportunistic hunter and its diet encompasses 87 species. The jaguar prefers large prey and will take deer, capybara, tapirs, peccaries, dogs, foxes, and sometimes even anacondas and caiman. However, the cat will eat any small species that can be caught, including frogs, mice, birds, fish, sloths, monkeys, and turtles.
Tiger, Pooh's Friend in Winnie The Pooh
Camel, Undefeatable Animal in Dessert
The average life expectancy of a camel is 40 to 50 years. They can run at up to 65 km/hour in short bursts and sustain speeds of up to 40 km/hour
Actually, camels do not store water in their humps as is commonly believed. The humps are actually a reservoir of fatty tissue. Concentrating body fat in their humps minimizes heat-trapping insulation throughout the rest of their body, which may be an adaptation to living in hot climates. Their ability to withstand long periods without water is due to a series of physiological adaptations.
