Hidden in the murky waters of the Yangtze River in China dwells an ancient species of dolphin unchanged by 20 million years of evolution. The Baiji Dolphin is the most endangered Cetacean in the world. The Baiji has a very long, narrow beak, with abrupt forehead and tiny eyes set high on the sides of the head. The triangular dorsal fin has a blunt peak. They are blue-grey in color, fading to white below. They grow to lengths up to 8 ft. and can weigh 200 lbs. The Baiji hunt for small fish in the river but it has been becoming increasingly difficult because of pollution in the water.
