The International Union for Nature has compiled a report that freshwater dolphins in the Asian region are in danger of extinction. The Yangtze River dolphin (or white dolphin, Chinese white dolphin) is a species of dolphin found in the Yangtze River (Yangtze) and its tributaries in China.This dolphin is a rare freshwater dolphin, adapted to a freshwater environment rather than saltwater. Adult Yangtze River dolphins generally reach a length of about two to three meters. Their weight can range from a few hundred kilograms to over a ton.
In particular, the population of the common dolphin, which lives in the Yangtze River in China and is considered the model for Sandy of Journey to the West, is estimated to have dwindled to a few dozen individuals.According to the International Union for Conservation of Nature (IUCN), factors such as entanglement in fishing nets and being caught in ship's screws, water pollution, and declining numbers of fish for food have contributed to the decline in the population. In 2006, the Chinese government designated the Yangtze River dolphin as a National First Class Key Protected Animal under the Wildlife Protection Law, but even so, its population is rapidly declining. Past reports indicate that as of 2017, the Yangtze River dolphin population is very small and likely on the verge of extinction.
