The GHARIAL, CROCODILE at BABAI river.
The GHARIAL,
also known as the gavial, and the fish-eating crocodile,
is a crocodilian of the familyGavialidae, native to the
northern part of the Indian
Subcontinent.
The Gharial is characteries by its extremely long, thin
jaws, which are regarded as an adaptation to a primarily piscivorous diet.
Males reach up to 6 m (20ft) with an average weight of around 160 kg (350lb).
It is dark or light olive above with dark cross-bands and
speckling on the head, body and tail. Dorsal surfaces become dark, almost
grey-black, at about 20 years of age. Ventral surfaces are yellowish-white. The
neck is elongated and thick. The dorsal ridges are more or less restricted to
the median regions of the back. The fingers are extremely short and thickly
webbed. Males develop a hollow bulbous nasal protuberance at the tip of the
snout upon sexual maturity. The name Gharial is derived from the resemblance of
the nasal growth to an earthen pot known locally as 'ghara'. Gharials are the
only extant crocodilian with visible sexual dimorphism. Although the function
of the nasal boss is not well understood, it is apparently used as a visual sex
indicator, as a sound resonator, or for bubbling or other associated sexual
behaviours.
