About the Baiji . They are beautiful creatures that can grow up to 2.60 m (8.5′) long and weigh about 167 kg (368 lbs). He was rescued in 1980 and spent more than 22 years at the Institute. They are also known as the Whitefin Dolphin, Yangtze Dolphin and White Flag Dolphin. Image credit: baiji.org.Due to their poor vision and the murky waters of the Yangtze River, baiji rely on sound for communication, orientation, and feeding. This particular dolphin has a similar appearance to other river dolphins with a stocky body, narrow upturned beak and a rounded melon with eyes set higher up on their head than most other dolphins. The location where they live, the temperature of the water, food sources, and even the species all play a factor. The baiji’s eyes were tiny and positioned higher up on the head than in other species of dolphin. Your chances of ever seeing a Baiji River Dolphin are incredibly slim. Since Baiji means 'white fin' in Chinese, it means 'white-finned dolphin'. The total teeth ranges from 30 to 36. For females, that age can range from 5 to 13. This particular dolphin is the first species of cetacean (marine mammals) to become extinct as a result of human activity.
