; subclass Archosauria, order Crocodilia)
A monospecific family (Gavialis gangeticus) comprising the Indian gharial (gavial) which is found in the Ganges, Indus, and Brahmaputra river systems. It is a fish-eater, with an elongate, narrow snout widening at the nostrils. Its teeth are all similar in shape and size. Tomistoma schlegeli (false gharial) is sometimes included in this family, but it is more probably a member of the Crocodylidae which has developed a long, narrow snout.
