- This is one of the largest crocodilians, reaching up to 6 metres occasionally and weighing over 1000kg. These crocodilians however, are piscivores meaning that they primarily eat fish. This is because of their long elongated and relatively weak snout that is not suited to grabbing large, struggling prey like mammals. As a result this is a relatively safe crocodilians to approach as long as you do not disturb or harm it it will leave you lone but this is no reason to become complacent as they have nearly a hundred long needle sharp teeth and they still have a vicious bite so should be treated with some caution.

- The fossil history of the Gavialoidea is quite well known, with the earliest examples diverging from the other crocodilians in the Late Cretaceous. The most distinctive feature of the group is the very long, narrow snout, which is an adaptation to a diet of small fish. Although gharials have sacrificed the great mechanical strength of the robust skull and jaw that most crocodiles and alligators have, and in consequence cannot prey on large creatures, the reduced weight and water resistance of their lighter skull and very narrow jaw gives gharials the ability to catch rapidly moving fish, using a side-to-side snapping motion.

- The fossil history of the Gavialoidea is quite well known, with the earliest examples diverging from the other crocodilians in the Late Cretaceous. The most distinctive feature of the group is the very long, narrow snout, which is an adaptation to a diet of small fish. Although gharials have sacrificed the great mechanical strength of the robust skull and jaw that most crocodiles and alligators have, and in consequence cannot prey on large creatures, the reduced weight and water resistance of their lighter skull and very narrow jaw gives gharials the ability to catch rapidly moving fish, using a side-to-side snapping motion. The earliest gharial may or may not have been related to the modern types: some died out at the same time as the dinosaurs (at the end of the Cretaceous), others survived until the Early Eocene The modern forms appeared at much the same time, evolving in the estuaries and coastal waters of Africa, but crossing the Atlantic to reach South America as well. At their peak, the Gavialoidea were numerous and diverse, they occupied much of Asia and America up until the Pliocene. One species, Rhamphosuchus crassidens of India, is believed to have grown to an enormous 15 meters (~50 feet) or more.

This species has never killed a human because they are usually a shy species that would rather swim off than attack as more aggressive crocodilians like the nile and cuban crocodile. In fact this is one of the most aquatic of all crocodilians, spending its entire life in water and only coming out to lay its eggs and to bask. This species lives alongside the mugger crocodile (crocodylus palustris) successfully because they occupy 2 different ecological niches and have different types off food whereas the gharial tends to go for fish-the mugger prefers larger prey like bovines.
