Crocodiles (subfamily Crocodylinae) or genuine crocodiles are huge sea-going reptiles that live all through the tropics in Africa, Asia, the Americas and Australia. Crocodylinae, the greater part of whose individuals are viewed as genuine crocodiles, is delegated an organic subfamily. A more extensive feeling of the term crocodile, Crocodylidae that incorporates Tomistoma, is not utilized as a part of this article. The term crocodile here applies just to the species inside of the subfamily of Crocodylinae. The term is some of the time utilized much all the more freely to incorporate every single surviving individual from the request Crocodilia, which incorporates Tomistoma, the gators and caimans (family Alligatoridae), the gharials (family Gavialidae), and all other living and fossil Crocodylomorpha.
In spite of the fact that they seem, by all accounts, to be like the untrained eye, crocodiles, gators and the gharial have a place with isolated natural families. The gharial having a tight nose is less demanding to recognize, while morphological contrasts are more hard to spot in crocodiles and gators. The most evident outside contrasts are unmistakable in the head with crocodiles having smaller and more heads, with a more V-molded than a U-formed nose contrasted with gators and caimans. Another evident characteristic is the upper and lower jaws of the crocodiles are the same width, and teeth in the lower jaw fall along the edge or outside the upper jaw when the mouth is shut; in this manner all teeth are unmistakable dissimilar to a gator; which has little dejections in the upper jaw where the lower teeth fit into. Likewise when the crocodile's mouth is shut, the expansive fourth tooth in the lower jaw fits into a tightening in the upper jaw. For difficult to-recognize examples, the jutting tooth is the most dependable element to characterize the family that the species has a place to.[1] Crocodiles have all the more webbing on the toes of the rear feet and can better endure saltwater because of specific salt organs for sifting through salt, which are available however non-working in gators. Another attribute that isolates crocodiles from different crocodilians is their much more elevated amounts of aggression.[2]
Crocodile size, morphology, conduct and biology to some degree contrasts between species. Notwithstanding, they have numerous similitudes in these zones too. All crocodiles are semiaquatic and have a tendency to assemble in freshwater living spaces, for example, streams, lakes, wetlands and now and again in salty water and saltwater. They are rapacious creatures, encouraging for the most part on vertebrates, for example, fish, reptiles, fowls and warm blooded creatures, and some of the time on spineless creatures, for example, molluscs and scavangers, contingent upon species and age. All crocodiles are tropical species that not at all like gators, are exceptionally delicate to frosty. They initially isolated from different crocodilians amid the Eocene age, around 55 million years ago.[3] Many species are at the danger of annihilation, some being delegated fundamentally imperiled.
