Ganges River Dolphin -- The Finest Aquatic Mammal

The Ganges River Dolphin is blind as its eyes do not have the seeing power that is to say simply it lacks optical lens.

Its Long Snout enables it to browse the banks of the Ganga and its tributaries for River Fish. Its Fin is quite small in comparison to the rest of its body.

The Ganges River Dolphin depends exclusively on Echolocation to detect schools of River Fish for its daily and weekly sustenance.

This Aquatic Mammal has to constantly live in muddy waters of the mighty Ganga River and its associated tributaries.

One gets a thrill as a Wildlife Lover to see it perform different aquatic stunts in the Ganga.

The Female Ganges River Dolphin is bigger in size than the Male. A Female Dolphin on average weighs about 100 Kilos or more.

A Female Ganges River Dolphin is ready to give birth to Calves at the age of 10 years at the earliest and at the age of 12 years at the latest.

Calves, when they are born are usually dark in colour but as they grow to full maturity they become "Pink" in colour.

Since, the Ganges River Dolphin is an aquatic mammal it can survive in River Water of varying temperatures.

In the past, it was assumed that there were 5,000 or more Dolphins existing in the Ganga and Brahmaputra River Systems in North India and North- East India respectively.

But, now it seems only 2,000 Ganges River Dolphins or less exist in these two River Systems namely the Ganga and mighty Brahmaputra.

Let us act to save this Mammal before it is too late.
