  Gharial - Wikipedia, the free encyclopedia
If the three surviving groups of crocodilians are regarded as separate families, then the gharial becomes one of two members of the Gavialidae, which is related to the families Crocodylidae (crocodiles) and Alligatoridae (alligators and caymans).
Alternatively, the three groups are all classed together as the family Crocodylidae, but belong to the subfamilies Gavialinae, Crocodylinae, and Alligatorinae.
Finally, palaentologists tend to speak of the broad lineage of gharial-like creatures over time using the term Gavialoidea.

 RedOrbit NEWS | Combined support for wholesale taxic atavism in Gavialine crocodylians
However, the molecular topology implies a suspiciously large number of evolutionary character reversals, i.e., taxic atavisms (Stiassny, 1992), that are concentrated in Gavialinae (Densmore, 1983; Hass et al., 1992).
The anatomical distributions of characters that unequivocally supported a grouping of Gavialinae and Tomistominae (red circles) and traits that were consistent with widespread taxic atavism in Gavialinae (purple and blue circles).
When fossils were excluded from analysis, the different states in G. gangeticus and T. schlegelii were each equivocally optimized as uninformative autapomorphies, but in the combined evidence topology with extinct taxa considered the state in G. gangeticus was most simply interpreted as an accentuation of the primitive "tomistomine" condition (Fig.

 What are Dermal Pressure Receptors?
In these species Dermal Pressure Receptors are restricted to the head area, mainly found along the jawline, eyes, nose and upper palate.
Animals in the Crocodylinae and Gavialinae families, which include crocodiles, have DPRs distributed over their entire bodies.
Dermal Pressure Receptors were previously called Integumentary Sense Organs (ISOs) because of their location in the integumentary or outer layer of the skin.

There are 22 species in the Crocodylidae Family which is divided into three subfamilies, namely: the Crocodylinae, the Alligatorinae, and the Gavialinae.
Crocodiles and alligators are found between the latitudes of Cancer (23.5º north) and Capricorn (23.5º south), in the rivers and lakes of South America, Africa, Asia and Australia.

 Palaeos Vertebrates: 290.400 Crocodylomorpha: Crocodylia
Introduction: There is some dispute over what taxa to include in this family of relatively unspecialised eusuchians.
Rodney Steel (1973) in Encyclopedia of Paleoherpetology vol 16 (Crocodylia) included five subfamilies - Crocodylinae, Alligatorinae, Gavialinae, Thoracosaurinae / Tomistominae (false gavials), and the extinct terrestrial Pristichampsinae.
Sometimes the Gavialidae was considered a distinct family, as in the wonderful (and long out of print) natural history book The Living World of Animals, (1970, The Reader's Digest Association).

The family Crocodylidae consists of small to very large amphibious carnivorous reptiles that contain twenty-two species in three subfamilies: Alligatorinae (alligators, caiman, from the New World), Crocodylinae (crocodiles, pantropical), and Gavialinae (gavials, from India and Burma) and may also be regarded as separate families.
The family Crotalidae consists of pit vipers and sidewinders with about 130 species of snakes (Serpentes) that possess heat-sensitive organs just behind the nostrils and feed on small vertebrates.

In fact, the twenty-three species of crocodilians all over the world (except Europe) are, fascinatingly, the closest thing to a dinosaur left.
There are three subfamilies: alligatorinae (the alligators of China and the USA, whose lower teeth cannot be seen when their mouths are closed, and South America's caimans); crocodylinae, "true" crocodiles; and gavialinae, the pin-nosed gharials.
All have integumentary sense organs, sensory cells in their thick scaly skin, but alligators and caimans only have them around jaw, nose, and eyes, while crocodiles and gharials have them all over the body.826
