In a Crocodile picture, you can see many various crocodiles, because there are many species and subspecies of the Order Crocodilia that vary in size, body structure, and occur in various areas. The term Crocodile is often used to include all members of the order Crocodilia, which is not correct. The Order Crocodilia includes the family Alligatoridae represented by alligators and caimans; the family Crocodilidae, represented by crocodiles; and the family Gavialidae, represented by gharials and false gharials. There are also many hybrids between species.
The true Crocodiles (from the family Crocodilidae) are large aquatic reptiles that are found throughout the tropics in Asia, Americas, Australia, and Africa. There are many living species of the Crocodile and several extinct species. Fossil Crocodile picture galleries prove that some ancient relatives of modern Crocodiles were herbivorous and could not compete with other herbivorous animals. Those that survived up to nowadays were very adaptable and efficient hunters.
Body length greatly varies between Crocodile species. The smallest one is the Dwarf Crocodile that reaches up to 3.3 ft, and the largest one is the Saltwater Crocodile with average body length around 16 ft and over 2,600 lbs in weight. Prehistoric ancestors of the Crocodile were twice as large as the largest Crocodile of today. In some Crocodile picture galleries, you can see a size comparison of Crocodile species with humans.
The Crocodile is a very complex reptile well adapted to both aquatic and terrestrial lifestyle. It’s one of the most successful predators in history. Its method of hunting is grabbing and holding onto the prey. Its muscles that close the jaws are very powerful; the teeth are large and very strong. The bite force of the Crocodile is ten times as much as that of the Great White Shark. A streamlined body and webbed feet allows Crocodiles to swim swiftly and make fast turns. The nostrils can be closed when underwater; the entry of water is blocked by a rigid palatal flap. The scales of the Crocodile have sensory pores, though some scientists believe they are glands producing oily substance protecting from mud. Scientists continue to investigate these creatures, as little is known about their adaptations. It’s very difficult to study them and make Crocodile picture galleries in their natural habitats.
