Crocodiles Rule The Waters With Their Strong Bodies And Thick Armour
Crocodiles are typical large-sized aquatic reptiles found in Africa, Asia, Americas and Australia. Several species of crocodiles have been pushed to the verge of extinction thanks to rampant hunting of crocodiles for their hides.
Crocodiles are quite similar to alligators when it comes to looks and body make-up. Crocodiles have their heads a bit narrower and longer than alligators. Crocodiles have the upper and lower jaws of the same width.
They are deft swimmers, and can tuck in their legs for the purpose of swimming. This way, water resistance is pulled down, and the speed of the crocodile in the water is pushed up. Their webbed feet enable them to propel and push themselves through the water. They enable them to take sudden turns and sharp movements within water while in pursuit of a prey.
The most prominent aspect of crocodiles is that their size, body structure and their adapted behavior varies with different species. But they are similar in several ways also. All of them are semi aquatic in nature. They love to be in habitats like rivers and lakes. All of them are carnivorous, and their diet includes mainly vertebrates like fishes, birds and mammals. But they are also fond of devouring invertebrates like mollusks and crustaceans. All of them are a bit sensitive to cold.
The bellies and sides of crocodiles are lined with smooth skin. The dorsal surface of a crocodile is lined up with osteoderms. They serve as an armour for the crocodile. The armour's ability to absorb sun's heat is explained by the track of minute capillaries that line the scale.
