The rarest dolphin is the Yangtze River Dolphin. (Baiji) The Baiji or Yangtze River Dolphin has been declared extinct since 2006.
Like any aquatic animal, the Yangtze river dolphin couldn't travel over land to get into a different river system. The only way to get to another river system would have been to swim out of the mouth of the Yangtze and along the coast until they reached the mouth of another river. However, the dolphins didn't know that there were any other river systems to escape to, and even if they had, they couldn't have crossed the ocean because they were a freshwater species and didn't have kidneys adapted for filtering enough salt out of their bodies that they could drink seawater.
In 2007 there was a reported sighting of a Yangtze River dolphin, or Baiji, which had been previously thought to be extinct.
The Yangtse River has existed since the world has been in its peresent form, so it has beenn there for millions of years.

Dolphins do not live in lakes. They mostly live in the ocean, or sea. There have been river dolphins, however, found in South America.
Yes, the Yangtze River does meander in certain sections, particularly in its middle and lower reaches. These meanders are created by the river's natural flow dynamics, which erode the banks and create bends over time. However, the river's course has also been significantly altered by human activities, such as dam construction and flood control measures. Overall, while the Yangtze exhibits meandering characteristics, its flow has been influenced by both natural and anthropogenic factors.
