Indian Gharial (Gavial) - Gavialis gangeticus
The gharial (Gavialis gangeticus) is a crocodilian of the family Gavialidae that is native to the Indian subcontinent and also called gavial and fish-eating crocodile. The gharial is one of three crocodilians native to India, apart from the mugger crocodile and the saltwater crocodile. It is one of the longest of all living crocodilians. Gharials' well-developed laterally flattened tail and webbed rear feet provide tremendous manoeuvrability in their deepwater habitat. On land, however, an adult gharial can only push itself forward and slide on its belly. Further enhancing its swimming abilities, the body of the gharial is relatively cylindrical in shape, compared with the broader, more powerfully-built body of a saltwater or nile crocodile built for capture various prey from the edges of waterways. The Gharial's elongated, narrow snout becomes proportionally shorter and thicker as an animal ages. The average body weight of the species is from 159 to 250 kg (350 to 550 lb). Males commonly attain a total length of 3 to 5 m (9.8 to 16 ft), while females are smaller and reach a body length of up to 2.7 to 3.75 m (8.9 to 12.3 ft). The three largest examples reported were a 6.5 m (21 ft) gharial killed in the Gogra River of Faizabad in August 1920; a 6.3 m (21 ft) individual shot in the Cheko River of Jalpaiguri in 1934; and a giant of 7 m (23 ft), which was shot in the Kosi River of northern Bihar in January 1924. Such exceptionally larger specimens can scale up to 977 kg (2,150 lb) in mass. While specimens of over 6 m (20 ft) were not uncommon in the past, such large individuals are not known to exist today. Gharials are exceeded in length only by the saltwater crocodile.
False Gharial - Tomistoma schlegelii
The false gharial (Tomistoma schlegelii), also known as the Malayan gharial, or false gavial is a freshwater crocodile of the Crocodylidae family with a very thin and elongated snout. The signature feature of the species is its extremely long and slender snout, which is even slimmer than the snout of the Slender-snouted crocodile's and comparably as slender as that of the Gharial or the Freshwater crocodile. It is dark reddish-brown above with dark brown or black spots and cross-bands on the back and tail. Ventrals are grayish-white, with some lateral dark mottling. Juveniles are mottled with black on the sides of the jaws, body, and tail. The snout is smooth and unornamented, and 3 to 3.5 times the width at the base. All teeth are long and needle-like, interlocking on the insides of the jaws, and are individually socketed. The fingers are webbed at the base. Integumentary sensory organs are present on the head and body scalation. Scales behind the head are frequently a slightly enlarged single pair. Some individuals bear a number of adjoining small keeled scales. Scalation is divided medially by soft granular skin. Three transverse rows of two enlarged nuchal scales are continuous with the dorsal scales, which consist of 22 transverse rows of 6 to 8 scales, are broad at mid-body and extend onto the sides of the body. Nuchal and dorsal rows equals a total of 22 to 23 rows. It has 18 double crested caudal whorls and 17 single crest caudal whorls. The flanks have one or two longitudinal rows of six to eight very enlarged scales on each side. Adult males weigh 150 to 250 kg (330 to 550 lb), while females are about 3.2 m (10 ft) long and weigh an average of 90 kg (200 lb).
