Rock monitor lizard



Taxonomy
First described by François Marie Daudin in 1802,[1] these lizards were previously classified as a subspecies of Varanus exanthematicus,[3] but have since been declared a distinct species based upon differences in hemipenal morphology.[4] The generic name Varanus is derived from the Arabic word waral ورل, which is translated to English as "monitor". Their specific name comes from a compound of two Latin words: albus meaning "white" and gula meaning "throat".

Description
The heaviest bodied and second longest lizard (the Nile monitor is longer) in Africa, they reach upwards of 2 metres (6 ft 7 in) in length, with the tail and body being of equal size. The head and neck are the same length, and are distinct from each other. Their bulbous, convex snouts give an angular, box-like appearance. Their forked tongues are pink or bluish,[6] and their scales are usually a mottled gray-brown with yellowish or white markings.

Intelligence
An intelligent lizard, several specimens have demonstrated the ability to count as high as six in an experiment conducted by Dr. John Philips at the San Diego Zoo in 1999. Philips offered varying numbers of snails, and the monitors were able to distinguish numbers whenever one was missing.

Alligator and crocodile



There are 23 species in the crocodile family, including alligator caimans and gavial. All are large reptile with long bodies and short legs. Most alligator and caimans have wide U-shaped snout but crocodile have narrow v-shaped snout. The gavial has very long slender jaw- just right for catching fish. In alligator and caimans the teeth of the lower jaw fit into pit in the upper jaw and cannot be seen when the mouth is closed. In the crocodile the fourth tooth on each side of the lower jaw fit into notch in the upper jaw, so they are always visible. Crocodile are generally bigger and more aggressive than alligator

Dinosaur's fact file



Dinosaurs first appeared about 230 million year ago during the Triassic period, These amazing reptile then dominated life of Earth until they become were Megalosaurus (Great lizard) by William Buckland in 1824 and Iguanodon (Iguana tooth) by Gideon Mantell in 1825 they were named before the word "Dinosaurs" had been invented. The name dinosaurs (Terrible lizard) was suggest by British scientist Richard Owen in july 1841. Since then 700 different species have been identified. Not all dinosaur were enormous- some measured less than 60 cm long about the size of chicken.

The Gaint of the sea



Whales are mammals, they give birth to their young ones. Scientist call them Cetaceans from the Latin word "Cetus" meaning whale. There are mainly two kind of whale Baleen and toothed. Baleen whale have large whale bones hanging from the upper jaw. The baleen whale is a Blue whale. It is the largest animal on earth- 100 feet long from head to tail it weight is 150 tones or 15000 Kilogram- More than 20 African elephant together. Though so big the blue Gray and other baleen whale eat only very small sea animal. The Toothed Whale have two rows of teeth just like us. They hunt and eat different fishes and seal. The Sperm Whale the Orca or Killer whale and Dolphin are all toothed whale. The Dolphin is friendly to man. It is also very intelligent. Pet dolphin perform tricks at many marine circuses

Cobra



The king cobra (Ophiophagus hannah) is the world's longest venomous snake, with a length up to 5.6 m (18.5 ft).[1] This species is widespread throughout Southeast Asia and parts of India, and is found mostly in forested areas. The king cobra can be fierce and agile, and can deliver a large quantity of highly potent venom in a single bite. It is one of the most dangerous and feared Asiatic snakes

Habitat
The king cobra is distributed across South Asia, Southeast Asia, and the southern areas of East Asia (southern China) but is not common. It lives in dense highland forests, preferring areas dotted with lakes and streams. King cobra populations have dropped in some areas of its range because of the destruction of forests. It is listed as an Appendix II Animal within CITES.

Defense
The king cobra can be highly aggressive.[9] When threatened, it raises up the anterior portion of its body, flattening the neck, showing the fangs and hissing loudly. (Bioacoustic analysis of the "growl" of the king cobra has shown that it differs significantly from other snakes. Generally a typical snake hiss has a broad-frequency span (~3,000 to 13,000 Hz) with a dominant frequency near 7,500 Hz, whereas the "growl" of the king cobra consists of frequencies below 2,500 Hz, with a dominant frequency near 600 Hz.) It is easily irritated by closely approaching objects or sudden movements. The king cobra attacks quickly, and the strike distance is about 2 m (7 feet); people can easily misjudge the safe distance. The king cobra may deliver multiple bites in a single attack, or bite and hold on. Although it is a highly dangerous snake, it prefers to escape unless it is cornered or provoked.[

If a king cobra encounters a natural predator, such as the mongoose, which has some resistance to the neurotoxins, the snake generally tries to flee. If unable to do so, it forms the distinctive cobra hood and emits a hiss, sometimes with feigned closed-mouth strikes. These efforts usually prove to be very effective, especially since it is more dangerous than other mongoose prey, as well as being much too large for the small mammal to kill with ease
