Crocodiles (lat. Crocodilia) are an order of tropical predators. Along with birds, they are the only surviving "descendants" of a large group of reptiles, Archosauria. Therefore, their recent closest relatives are birds. Their kinship is provable by a whole range of characteristics, but above all by the structure of the blood circulation system. Because of their bone armor, crocodiles are also called armored lizards.All crocodiles living today live in rivers and lakes of tropical areas and subtropical areas, only the estuarine crocodile (Crocodylus porosus) can live in the sea and often appears along the shores of various islands. In order to adapt to the environment, these animals swim very well and hide in the water by resting immersed in water, with only their eyes and nostrils emerging from the water. Today's living crocodiles are divided into three groups with the status of a family (alternatively, they are often shown as one family Crocodylidae and three groups as subfamilies within it): true crocodiles, alligators and gavials.
