The Biggest Animals Kingdom and in The World | Nile crocodile | In antiquity, Nile crocodiles occurred in the Nile delta Zarqa River (Jordan) and recorded by Herodotus who inhabited Lake Moeris. In Madagascar, crocodiles occur in the western and southern parts of the Sembirano in Port Dauphin. Until recently, many permanent waters in the Sahara still housed relict populations. Found in East Africa, particularly in rivers, lakes, wetlands and reservoirs. The species was probably widespread in West Africa, but these populations are now recognized as a distinct species, the crocodile desert. Nile crocodiles have a dark bronze colouration above, with black spots on the back and a dirty purple on the belly. The sides are yellowish green dark spots are arranged in diagonal stripes.
Like all crocodiles, the Nile crocodile is a quadruped with four short legs wide apart, a long tail and powerful, scaly skin with rows of bony shields. Along the back and tail and powerful jaws must protect the nictitating membranes around the eyes and tear ducts to rinse your eyes with tears. The belly is yellow-green, and makes high-quality leather. Smaller specimens can gallop, crocodiles are even more impressive explosions capable of reaching a speed of only 12 to 14 km / h (7.5 to 8.7 mph). The skin has a number of poorly understood organs integumentary (ISO), which can react to changes in water pressure. The bite force of an adult Nile crocodile has been exercised by Dr. Brady Barr demonstrated that measure 5,000 lbf (22 kN).
On each side of the mouth, there are five teeth in the front part of the upper jaw (premaxilla), 13 or 14 in the rest of the upper jaw (OK) and 14 and 15 on each side of the lower jaw (mandible). Out of the water can crocodiles competition from other predators of the savannah dominant, particularly cats such as lions and leopards. Occasionally both big cats and crocodiles and prey are hunted each other, depending on the size, when food is scarce normal The Nile crocodile is the largest crocodile in Africa and is sometimes regarded as the second largest after crocodile saltwater crocodile. The male crocodile usually measure from 3.5 to 5 meters (11-16 feet) in length, but very old, mature ones can grow up to 5.5 meters (18 feet) or more. Like all crocodiles they are sexually dimorphic, with males being larger up to 30% of women, although the difference. Even in some species, such as the saltwater crocodile Mature Nile crocodiles measure 2.4 to 4 m (7 ft 1 in 10-13 ft). Weight typical Nile crocodile is 225-500 kg (500-1100 pounds), although males of large size up to 750 kg (1,700 lb) can be in the crowd.
The proof of Nile crocodiles from cooler climates, such as the southern tip of Africa is small in size and can reach lengths of only 4 m (13 ft). Out of the water, however, the Nile crocodile count on the tip (such as galloping ground) hunting for prey. [16] Most of the hunting must be done at night when lying in ambush near forest trails or roadsides, up to 50 meters (170 feet) from the water's edge puppies usually eat smaller animals, insects prefer and small aquatic invertebrates before the purchase of fish, amphibians and small reptiles. Teens and subadults a wide variety of prey with additions such as birds and mammals of small and medium-sized enterprises. During his life, both young and adult crocodiles on fish and other small vertebrates eat at different times, particularly when food is absent, as food side. Adult predators and prey of other birds, reptiles and mammals, as well as also prey on young people and children are consumed. Among the mammals, caught in gazelles, antelope, antelope, Sitatunga, lechwe, wildebeest, zebras, warthogs, giraffes, buffalo, though. The opportunity known to prey on domestic fowl, goats, sheep and cows Nile Crocodiles eat people too often, much more often than other types of crocodiles (although in some areas of the Philippines and New Guinea, attacked by crocodiles salt water can also common).
Adult Nile crocodiles her body and tail. The dominant crocodile eats first. Their ability to hide most of his body are under water, in combination with their speed over short distances, makes them effective opportunistic hunters of larger prey. They grab prey in their powerful jaws, drag it into the water, and hold it until it drowns. Groups of Nile crocodiles may travel hundreds of meters of a watercourse to enjoy a channel. Once the prey is dead, rip and swallow pieces of meat. If groups share a kill, they use each other to use, bite hard and then twisting their bodies in order to remove large pieces of meat on a "death list".
