The Indian gavial (Gavialis gangeticus) [see illustration] is confined to the Ganges River and its tributaries and may attain a length of 9 m (30 ft), whereas the Malayan gavial (Tomistoma schlegelii) is found in Borneo and Sumatra and has a maximum length of approximately 4.5 m (15 ft).

(Photo courtesy of Kevin A. Boudreaux) The gavial (also known as gharial) is distinguished from other members of the order by its extremely long, slender snout. The tip of the snout is enlarged, and fleshy elevations surround the openings of the nostrils. The mouth cavity is lined with long, stout, sharp-edged teeth, with the upper set interlocking with the lower set. Gavials feed almost exclusively on fish. They are timid animals and, when alarmed, move with great rapidity into the nearby water. Female gavials lay about 30–40 eggs in nests that have been prepared (by the females) on the riverbanks. The newly hatched young are about 0.3 m (1 ft) in length and quite active. Charles B.
