Cheetahs’ sprints have been measured at a maximum of 114 km (71 miles) per hour, and they routinely reach velocities of 80–100 km per hour while pursuing prey. Nearly all the cheetahs remaining in the wild live in Africa. Cheetahs are covered almost entirely with small black spots on a background of pale yellow and have a white underbelly. Their faces are distinguished by prominent black lines that curve from the inne

Extensive work was subsequently done to straighten the tower, and its lean was ultimately reduced to less than 4.0 degrees. The bell tower, begun in 1173 as the third and final structure of the city’s cathedral complex, was designed to stand 185 feet (56 metres) high and was constructed of white marble. Three of its eight stories had been completed when the uneven settling of the building’s f

 quokka Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Infraclass: Marsupialia Order: Diprotodontia Family: Macropodidae Subfamily: Macropodinae Genus: Setonix Species: S. brachyurus The quokka also known as the short-tailed scrub wallaby (Setonix brachyurus), is a small macropod about the size of a domestic cat. It is the only member of the genus Setonix. Like other marsupials in the macropod family (such as kangaroos and wallabies), the quokka is herbivorous and mainly nocturnal. A quokka weighs 2.5 to 5.0 kg (5.5 to 11 lb) and is 40 to 54 cm (16 to 21 in) long with a 25-to-30 cm-long (9.8-to-12 in) tail, which is quite short for a macropod. It has a stocky build, well developed hind legs, rounded ears, and a short, broad head. Its musculoskeletal system was originally adapted for terrestrial bipedal saltation, but over its evolution, its system has been built for arboreal locomotion. Although looking rather like a very small kangaroo, it can climb small

 Dragon Illustration of a winged, fire-breathing dragon by Friedrich Justin Bertuch from 1806 dragon, in the mythologies, legends, and folktales of various cultures, a large lizard- or serpent-like creature, conceived in some traditions as evil and in others as beneficent. In medieval Europe, dragons were usually depicted with wings and a barbed tail and as breathing fire. In Greece the word drakōn, from which the English word was derived, was used originally for any large serpent (see sea serpent), and the dragon of mythology, whatever shape it later assumed, remained essentially a snake. In general, in the Middle Eastern world, where snakes are large and deadly, the serpent or dragon was symbolic of the principle of evil. Thus, the Egyptian god Apepi, for example, was the great serpent of the world of darkness. But the Greeks and Romans, though accepting the Middle Eastern idea of the serpent as an evil power, also at times conceived the drakontes as beneficent—sharp-eyed dwellers in

 pangolins Ranges of living species COMMON NAME:  Pangolins DIET:  Insectivore SIZE:  45 inches to 4.5 feet long WEIGHT:  4 to 72 pounds Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Mirorder: Ferae Clade: Pholidotamorpha Order: Pholidota pangolin, (family Manidae), also called scaly anteater, any of about eight species of armoured placental mammals of the family Manidae (order Pholidota). The name pangolin, from the Malay meaning “rolling over,” refers to this animal’s habit of curling into a ball when threatened. Pangolins—which are typically classified in the genera Manis, Phataginus, and Smutsia—are found in tropical Asia and Africa. Pangolins are 30 to 90 cm (1 to 3 feet) long exclusive of the tail and weigh 5 to 27 kg (10 to 60 pounds). Across all eight species, adult tail length ranges from about 26 to 70 cm (approximately 10 to 28 inches). Except for the sides of the face and underside of the body, they are covered with overlapping brownish scales
