The [[Ganges and Indus river dolphin|Ganges river dolphin]], or "susu" occur in the [[Ganges]] and [[Brahmaputra]], south Asia's largest [[river]] systems. It can now be considered amongst the most endangered [[mammal]]s of the region.<br />
<br />
The [[Ganges and Indus river dolphin|Ganges river dolphin]] ranges from 2.3 to 2.6 meters in length. The tail fluke is on average 46&nbsp;cm in width. [[Female]]s are larger than [[male]]s. The color of this [[dolphin]] varies from lead-colored to black. The undersides are lighter in color. The rostrum is 18 to 21&nbsp;cm in length and the forehead is steep and rises abruptly from the base of the snout. The dorsal fin is rudimentary and ridge-like, and the ends of the pectoral [[fin]]s are squared instead of tapered. The neck is visibly constricted and the blowhole is a longitudinal slit. There are 28 to 29 teeth on either side of the jaw. The eye and optic nerve of the Ganges river dolphin are degenerate. The eye lacks a lens and is therefore incapable of forming images on the retina. However, it functions in light-detection. It is believed that the lack of a true visual apparatus in the river dolphin is related to its habitat; the water in which it lives is so muddied that vision in essentially useless.<br />
<br />
[[Valmiki National Park]], [[West Champaran district]], covering about 800&nbsp;km<sup>2</sup> of forest, is the 18th [[Tiger reserves of India|tiger reserve of India]], and is ranked fourth in terms of density of [[tiger]] population.<ref>[projecttiger.nic.in/valmiki.htm]</ref> It has diverse landscapes, sheltering rich wildlife habitats and floral and faunal composition, with the prime protected carnivores.<br />
