A crocodile is a large amphibious reptile. It lives mostly in large tropical rivers, where it is an ambush predator. One species, the Australian saltie, also travels in coastal salt water. In very dry climates, crocodiles may aestivate and sleep out the dry season.[1]
The modern type of crocodile appeared first in the Eocene period, but its ancestors go much further back, to the Upper Triassic. The name “Crocodile” is also used for any member of the order Crocodilia. They are basically Archosaurs, a group which also includes the dinosaurs. There are many species of Crocodiles including the American, slender-snouted and Orinoco crocodile.
The crocodile can snap its jaw shut quickly and with much power. But crocodiles have very little strength opening their jaws and a person could hold the jaw shut with their hands.
Crocodiles range in size from African Dwarf crocodiles that measure rarely over 5 feet to saltwater crocodiles which can approach 23 feet.
Although there is not much difference in their life-style, biologists put alligators in a separate family. Gharials are also in a separate family, and Caimans are a sub-family of alligators.
The difference between an alligator and a crocodile is that one can not see the fourth tooth in the lower jaw of an alligator when the alligator’s mouth is closed. One can see the fourth tooth in the lower jaw of a crocodile when its mouth is closed. Crocodiles are said to have narrower snouts than alligators, but there are also some crocodiles with wide snouts.
Crocodile size, morphology, behaviour and ecology somewhat differs between species. However, they have many similarities in these areas as well. All crocodiles are semiaquatic and tend to congregate in freshwater habitats such as rivers, lakes, wetlands and sometimes in brackish water and saltwater. They are carnivorous animals, feeding mostly on vertebrates such as fish, reptiles, birds and mammals, and sometimes on invertebrates such as molluscs and crustaceans, depending on species and age. All crocodiles are tropical species that, unlike alligators, are very sensitive to cold. They separated from other crocodilians during the Eocene epoch, about 55 million years ago.[3]Many species are at the risk of extinction, some being classified as critically endangered.
Etymology
The word “crocodile” comes from the Ancient Greek κροκόδιλος (crocodilos), “lizard”, used in the phrase ho krokódilos tou potamoú, “the lizard of the (Nile) river”. There are several variant Greek forms of the word attested, including the later form κροκόδειλος (crocodeilos)[4] found cited in many English reference works.[5] In the Koine Greek of Roman times, crocodilos and crocodeilos would have been pronounced identically, and either or both may be the source of the Latinized form crocodīlus used by the ancient Romans. Crocodilos or crocodeilos is a compound of krokè (“pebbles”), and drilos/dreilos (“worm”), although drilos is only attested as a colloquial term for “penis”.[5] It is ascribed to Herodotus, and supposedly describes the basking habits of the Egyptian crocodile.[6]
The form crocodrillus is attested in Medieval Latin.[5] It is not clear whether this is a medieval corruption or derives from alternative Greco-Latin forms (late Greek corcodrillos and corcodrillion are attested). A (further) corrupted form cocodrille is found in Old French and was borrowed into Middle English as cocodril(le). The Modern English form crocodile was adapted directly from the Classical Latin crocodīlus in the 16th century, replacing the earlier form. The use of -y- in the scientific name Crocodylus (and forms derived from it) is a corruption introduced by Laurenti (1768).
Size range and diversity of structure
Crocodiles are the largest and the heaviest of present-day reptiles. The largest representatives, the Nile crocodile (Crocodylus niloticus) of Africa and the estuarine (or saltwater) crocodile (C. porosus) of Australia, attain lengths of up to 6 metres (20 feet) and weigh over 1,000 kg (about 2,200 pounds). Some fossil forms (such as Deinosuchus and Sarcosuchus) may have been between 10 and 12 metres (33 and 40 feet) long. In comparison, the smallest species, the smooth-fronted caiman (Paleosuchus) and the dwarf crocodile (Osteolaemus tetraspis), reach about 1.7 metres (about 6 feet) in length as adults.
All crocodiles have a relatively long snout, or muzzle, which varies considerably in shape and proportion. The scales that cover most of the body generally are arranged in a regular pattern, and thick, bony plates occur on the back. Families and genera are primarily distinguished by differences in skull anatomy. Species are identified principally by the proportions of the snout; by the bony structures on the dorsal, or upper, surface of the snout; and by the number and the arrangement of the scales.
Crocodile of the largest living reptiles. Belongs to the species crocodilians, has a long body and short legs and a long tail that can swim strong, sharp teeth caught out on his prey, and there are 12 species of crocodiles, and wacky that it can not take out his tongue out of his mouth. Wikipedia
