DICHOTOMOUS KEY
[German]
The gharial is classified in a family of its own (gavialinae) on account of its somewhat different morphology, which is particularly evident in the shape of the skull (look at the shape of the cranial platform and the eye orbits). Of course, the jaws are extremely long and slender, but the false gharial (T. schlegelii) has similar jaws yet a more "crocodile-like" head.
