context_page_description: The gharial, sometimes called the Indian gharial, common gharial or gavial, is one of two surviving members of the family Gavialidae. They are a group of crocodile-like reptiles with long, narrow jaws.
  The gharial is the second-longest of all living crocodilians: a large male can be nearly six meters in length. Only saltwater crocodiles and the Nile crocodile can grow larger.
context_section_description: The Gharial has a long, narrow snout. This is the feature that is most different from most other Crocodilia. The only other species who has such a snout is the False gharial (Tomistoma schlegelii), which is closely related. The shape of this snout changes when the animal grows older. The snout becomes progressively thinner the older the gharial gets. There is a  bulbous growth on the tip of the male's snout. This is called a 'ghara' (after the Indian word meaning 'pot'). It is only present in mature animals. It is used for different activities, such as making a resonant hum during vocalization. It is also used for attracting females. The mating ritual includes a section where the male uses this ghara to make bubbles.
  The long jaws are lined with many interlocking, razor-sharp teeth. This is an adaptation to the diet (predominantly fish in adults). This species is one of the largest of all crocodilian species, approaching the saltwater crocodile (Crocodylus porosus) and the Nile crocodile in maximum size - males reach at least 5 metres in length, and often approach 6 metres. Reports of 7 metre animals exist, but are unconfirmed. The leg musculature of the gharial is not suited to enable the animal to raise the body off the ground (on land) in order to achieve the high-walk gait - being able only to push its body forward across the ground ('belly-sliding'), although it can do this with some speed when required. However, when in water, the gharial is the most nimble and quick of all the crocodiles in the world. The tail seems overdeveloped and is flattened on the side, more so than other crocodiles. This enables it to achieve the excellent swimming abilities.
  The gharial has 27 to 29 upper and 25 or 26 lower teeth on each side. These teeth are not received into interdental pits; the first, second, and third mandibular teeth fit into notches in the upper jaw. The front teeth are the largest. The gharial's snout is narrow and long, with a dilation at the end and its nasal bones are comparatively short and are widely separated from the pre-maxillaries. The nasal opening of a gharial is smaller than the supra-temporal fossae. The gharial's lower anterior margin of orbit (jugal) is raised and its mandibular symphysis is extremely long, extending to the 23rd or 24th tooth. A dorsal shield is formed from four longitudinal series of juxtaposed, keeled and bony scutes.
  The length of the snout is 3.5 (in adults) to 5.5 times (in young) the breadth of the snout's base. Nuchal and dorsal scutes form a single continuous shield composed of 21 or 22 transverse series. Gharials have an outer row of soft, smooth or feebly-keeled scutes in addition to the bony dorsal scutes. They also have two small post-occipital scutes.
  The outer toes of a gharial are two-thirds webbed, while the middle toe is one-third webbed. Gharials have a strong crest on the outer edge of the forearm, leg and foot. Typically, adult gharials are of a dark olive hue while young ones are pale olive, with dark brown spots or cross-bands.
