dinosours

Dinosaur, one of a group of extinct reptiles that lived from about 230 million to about 65 million years ago. The word dinosaur was coined in 1842 by British anatomist Sir Richard Owen, derived from the Greek words deinos, meaning arvelous or œterrible,‌and sauros, meaning lizard. For more than 140 million years, dinosaurs reigned as the dominant animals on land.Owen distinguished dinosaurs from other prehistoric reptiles by their upright rather than sprawling legs and by the presence of three or more vertebrae supporting the pelvis, or hipbone. Dinosaurs are classified into two orders according to differences in pelvic structure: Saurischia, or lizard-hipped dinosaurs, and Ornithischia, or bird-hipped dinosaurs. Dinosaur bones occur in sediments that were deposited during the Mesozoic Era, the so-called era of middle animals, also known as the age of reptiles. This era is divided into three periods: the Triassic (251 million to 200 mill

whales

Whale, large mammal that lives its entire life in the water. Whales have a fishlike body; however, their tail fins, called flukes, are horizontal rather than vertical, and they have paddlelike front limbs, called flippers. Their skin is smooth and glossy and, depending on the species, may be black, white, or a variety of colors and patterns. Beneath the skin is a thick layer of fat, called blubber, which provides insulation and serves as a source of storLion, one of the largest members of the cat family.

giving these animals the nickname king of beasts. Lions are also known for their mighty roar, a fearsome sound that can be heard by humans more than 8 km (5 mi) away..

Lions once ranged over vast areas on many continents. Fossil evidence shows that until about 10,000 years ago, lions lived throughout Africa, Europe, the Middle East, and into Asia as far as southern India and the island of Sri Lanka. They also lived in North America and northern South America. Since then, however, thelion

Fish

Fish, diverse group of animals that live and breathe in water. All fishes are vertebrates (animals with backbones) with gills for breathing. Most fish have fins for swimming scales for protection,and streamlined body for moving easily through the water. Fishes live in nearly every underwater habitatto have a white background.from near-freeziArctic waters to hot desert springs; from mud in dried-up tropical ponds to the deepest ocean abyss. Special antifreeze chemicals in the blood of Antarctic icefish enable them to survive in water below 0آ° C (32آ° F). Desertpupfish found in hot springs of western North America liveintemperatures higher than 40آ° C (100آ° F).

Cat

Cat, small, mainly carnivorous animal, Felis catus, member ofthe family Felidae, popular as a household pet, and valuable for killing mice and rats. Like other members of the cat family, the domestic cat has retractile claws; keen hearing and smell; remarkable night vision; and a compact, muscular, and highly supple body. Cats possess excellent memory and exhibit considerable aptitude for learning by observation and experience. The natural life span of domesticcaabou15 years. OMG :D EPIC

cobra

Cobra (snake), common name for certain members of a family of venomous snakes, known for their intimidating behavior and deadly bite. Cobras are recognized by the hoods that they flare when angry or disturbed; the hoods are created by the elongate ribs that extend the loose skin of the neck behind the cobras' heads. These reptiles are found throughout the Philippines, southern Asia, and Africa. The king cobra is the world's longest venomous snake. It averages 3.7 m (12 ft) in length but is known to grow to 5.5 m (18 ft). It is olive or brown in color, with bronze eyes; some individuals are banded. It is found in the Philippines, Malaysia, southern China, Myanmar (formerly known as Burma), India, Thailand, and the Malay Peninsula. It eats primarily other snakes. The other cobra of Asia is known variously as the common, Asian, Indian, or spectacled cobra (due to the eyeglass-shaped pattern on its skin). It seldom reaches a length of more than 1.8 m (6 ft). The hood of the common cobra isproportionately, much larger than that of the king cobra and isusually yellow to brown, with a black-and-white spectacle pattern on top and two black and white spots on the lower surface. This snake causes many deaths each year in India, where it is regarded with religious awe and is seldom killed. The common cobra is frequently used by snake charmers. It ranges from the eastern shore of the Caspian Sea to China and Malaysia.

Bat

that serve as wings capable of sustained flight. They have been flitting across the night skies since the Eocene Epoch, some 50 million years ago. In all this time, the physical features of these animals have changed very little. Fossil specimens from Europe and North America are nearly indistinguishable from living forms. There are nearly 1000 living bat species, accounting for almost a quarter of all mammal species. These species are divided among two major groups. The Megachiroptera, or megabats, are large animals, commonly known as Old World fruit bats. They are mainly fruit-eaters and are found only in tropical habitats of Africa, India, and Australasia. The Microchiroptera, or microbats, are smaller, eat a variety of foods from small mammals to fish, and are much more.

Horses

aremarkable variation in size, body shape, and coat color. Traditionally, a horse’s size is measured at the withers—anelevated part of the spine between the neck and theback. The measurement is made in hands; one hand equals about 10 cm (4in). Typical riding horses stand 14 to 16 hands high and weigh 400 to 500 kg (900 to 1,100 lb). The smallest horse on record, a Falabella miniature pony, stood 48 cm (19 in), or just under 5 hands, and weighed 14 kg (30 lb). The largest horse on record was a Belgian that stood 1.8 m (6 ft) tall, or 18 hands, and weighed 1,450 kg (3,200 lb)The horse has a hairy coat and a long mane and tail. A heavy winter coat grows in the fall and sheds in the spring. Typical coat colors include black, brown, gray, cream, gold, and white. The mane and tail can be the same or different from the body color, and many variations in color can result from inherited traits that cause spotting, dilution of the basic coat colors, or a sprinkling of white hairs in the coat. Many color patterns have speci
