Crocodile: Habits, Diet and Other Facts
The order crocodilia is an order of reptiles that brings together all crocodilians, mainly represented by crocodiles, alligators and gharials (found in India) - animals that live in warm environments and inhabit freshwater rivers and lakes, with few species found in salt water .
Crocodilians are carnivorous animals that have horny scales reinforced by dermal bony plates, which, when worn, are replaced by others. They have a heart divided into four cavities and well-developed senses. They have 30 to 40 teeth and the palate bone extends, separating the nasal cavity from the oral cavity. When underwater, the animal's nasal orifices close and the eardrums are protected by a fold of skin. With its muscular tail and flattened on both sides, the animal is able to defend itself with violent slashes, in addition to moving with precision in the water.
Crocodilians are animals that spend most of their lives underwater, but they like to stretch out on the sand along riverbanks to sunbathe.
In Brazil, the representatives of this order are the alligators, found in various regions of the country, such as the alligator-açu, alligator-of-oculars or alligator and alligator-de-papo-amarelo.
Unfortunately, many people appreciate the leather of these animals for making objects such as bags, shoes, belts, wallets, among others. For this reason, several species of crocodilians are threatened with extinction.
Some bird species, such as Pluviailis aegyptus, maintain a symbiotic relationship with some species of crocodilians. By keeping its mouth open, the crocodilian allows the bird to enter its mouth and eliminate the food debris that accumulates between its teeth, obtaining food in a plentiful and easy way. For the crocodilian this is very valid, as he is free of food debris, leeches and other parasites that invade his gums.
