The Chinese river dolphin is only found in the Yangtze River in China and may be extinct. It has a long, narrow and slightly upcurved snout. Its skin is light bluish-gray above and white on its underside. Adults can grow up to eight feet and can weigh up to 500 lb. Females are slightly smaller than males.
The Chinese river dolphin can only thrive in freshwater. Like most aquatic animals, this species uses echolocation, a process that involves emitting sound waves that bounce off objects in the water revealing their size and distance. The dolphins use this for locating food and recognizing potential danger, such as boats. Chinese river dolphins are opportunistic feeders and eat a large variety of freshwater fish species, including eel-like catfish. They are social and have been seen in groups of up to 16 individuals. Little is known about their reproductive behavior. Females give birth to only one calf after a gestation period of six to 12 months.
Causes of decline include habitat destruction, overfishing, pollution, and accidents during heavy river traffic. Conservation efforts have generally been unsuccessful. The species is legally protected, but
after a six-week scientific survey in the summer of 2007, conservationists concluded that the species may now be extinct.

Twelve Incredibly Odd Endangered Creatures
1. Solenodon The solenodon is a mammal found primarily in Cuba and Hispanola. The species was thought to be extinct until scientists found a few still alive in 2003. Solenodons only prefer to come out at night. They eat primarily insects and they are one of the few mammal species that are venomous, delivering a very powerful toxin. Symptoms of a solenodon bite are very similar to a snake bite, including swelling and severe pain, lasting several days.
