Gharial Hatchlings seen in Odisha
Forest Department of Odisha has witnessed an adult Gharial surrounded by 28 hatchlings at Satkosia gorge in Mahanadi river which is considered as southernmost limit of gharials’ home range in India.

How is it significant?
Ø Forest department
has been trying for 15 years to increase the population of gharials in their
natural habitat in Odisha. For long, the State Forest Department has been
trying to increase the population of gharials in their natural habitat in
Odisha. However, it yielded desired result. Thus, sight of mated gharials and
their hatchlings becomes significant.

The Gharial
Ø Gharial, also
called as gavial or fish-eating crocodile, is a crocodilian of family
Gavialidae. It is one among longest of all living crocodilians. Mature females
are 2.6–4.5 m long while and males are 3–6 m long. They are called as Gharial
because they have a distinct boss at the end of snout, resembling an
earthenware pot or ghara. They are well adapted to catching fish.
Ø
Background
Ø It is believed that
gharial evolved in northern Indian subcontinent. Because, Fossil gharial
remains were collected from Pliocene deposits in Shivalik Hills and Narmada
River valley.
Ø
Natural Habitat
Ø Currently, Gharials
inhabit rivers in northern plains of Indian subcontinent. They are most
thoroughly aquatic crocodilian. They leave water only for basking and building
nests on moist sandbanks.
Ø
Concerns
Ø Population of
gharial is declining dramatically since 1930s. they are limited to only 2% of
its historical range now. Loss of habitat is occurring because of sand mining
and conversion of agriculture, decreasing fish resources etc. Though, India and
Nepal started conservation programmes with focused on reintroducing
captive-bred gharials. But they are listed as ‘critically endangered’ in IUCN
Red List since 2007.
