High Quality Content by WIKIPEDIA articles! Ganges and The 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 mammals of the region. The Ganges River dolphin ranges from 2.3 to 2.6 meters in length. The tail fluke is on average 46 cm in width. Females are larger than males. The color of this dolphin varies from lead-colored to black. The undersides are lighter in color. The rostrum is 18 to 21 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 fins are squared instead of tapered. The neck is visibly constricted and the blowhole is a longitudinal slit.
