The Baiji, or Yangtze river dolphin, is a species of freshwater dolphin that was once abundant in the Yangtze River in China. It is believed to be the first mammal species to become extinct in modern times due to human activity.
The Baiji was an important part of Chinese culture for centuries and was even mentioned in ancient Chinese texts. It had a large body with a long, thin beak and could grow up to 2 meters long. Its diet consisted mainly of small fish and invertebrates, which it caught using its highly developed echolocation capabilities.
Unfortunately, the population of Baiji began to decline in the mid-20th century, due to overfishing and pollution in the Yangtze River. By the 1980s thir numbers had declined drastically and conservation efforts proved fruitless as no individuals could be located after a survey in 2006. Scientists declared them functionally extinct at this point as there were no known individuals left in the wild or captivity.
The Baiji’s extinction serves as a stark reminder of the dangers posed by human activities on wildlife populations and ecosystems arond the world. This tragedy highlights how important it is for us to work together to protect our planet’s biodiversity and ensure that species like the Baiji are not lost forever.
Estimating the Remaining Population of Baiji
At this time, it is believed that thee are less than 10 Baiji left in the world. The last confirmed sighting of a Baiji was in 2004, when Chinese scientists conducted an expedition on the Yangtze River in search of the species. After a six week survey, no Baiji were found and it is now feared that this species may be extinct. The decline of the Baiji population has been attributed to a number of factors such as pollution, overfishing and construction projects in its natural habitat.

Are There Any Remaining Baiji?
Unfortunately, the answer to the question is no. The baiji, or Chinese River Dolphin, was last sighted in August 2004 and there have been no confirmed sightings sice then. This has led to the conclusion that the species is now extinct. The baiji was listed as an endangered species by the U.S. government under the Endangered Species Act and its extinction is thought to be due to overfishing, water pollution and boat traffic in the Yangtze River where it lived. Conservation efforts have been unsuccessful and its extinction highlights how important it is for us to protect our environment and look after endangered species before it’s too late.
The Extinction of the Baiji River Dolphin
The baiji, also kown as Yangtze River Dolphin, is a freshwater dolphin species endemic to China’s Yangtze River. It was declared functionally extinct in 2006 due to a combination of factors that caused its population to decline drastically over the past few decades.
The primary cause of the baiji’s extinction was unsustainable fishing practices. Fishing nets with hooks were used to catch fish in the river, and thee nets often snagged and drowned dolphins as bycatch. Additionally, pollution from heavy industry and agricultural runoff had a detrimental impact on the water quality of the Yangtze River, reducing the available food sources for the baiji and further contributing to their decline.
Habitat fragmentation caused by construction of dams and other human development activities along the river also likely played an important role in the baiji’s extinction. These activities disrupted migration patterns and reduced available habitat for them, making it difficult for the dolphins to find sufficient food or mates for reproduction.
Finally, overfishing reduced fish stocks throughout the Yangtze River basin, furthr limiting prey availability for baiji. The combination of these factors created an unsustainable situation for this species, leading to its ultimate demise.
The Fate of Captive Baiji Dolphins
No, there are currently no baiji in captivity. Qi Qi was the last known baiji in captivity when he died in 2002. He had been living at the Institute of Hydrobiology in Wuhan, China since 1980. The species is now considered to be functionally extinct due to rapid declines in population size caused by a combination of habitat loss, pollution, and overfishing. Conservation efforts have been unsuccessful in preventing the extinction of this species.

Last Sighting of the Baiji
The last confirmed sighting of the baiji was in 2004 in the Yangtze River in China. The baiji had been declining in population since the mid-20th century, and by 1998 there were only seven individuals believed to remain. The last known living baiji, Qi Qi, was kept in captivity at the Institute of Hydrobiology in Wuhan, China until his death in 2002. Despite extensive searches and conservation efforts, no wild baijis have been seen since 2004 and the species is now considered functionally extinct.
The Extinction of the Dolphin
The Baiji (Lipotes vexillifer) was a species of freshwater dolphin that was once found in the Yangtze River in China. It is believed to have been around for 20 million years, but it was declared extinct in 2006. This made it the first dolphin species to be declared extinct in modern times.
The Baiji had a long narrow body, a curved dorsal fin, and light grey-blue skin with white patches on its belly. It measured up to 2 metres long and weighed up to 230 kilograms. The Baiji usually travelled in small pods of two or three individuals and fed on carp and other fish near the surface of the river.
Unfortunately, the decline of this species has been attributed to human activity such as overfishing, boat traffic, water pollution, and habitat destruction. In 1997, a survey estimated that only thirteen individuals were left in the wild before they were declared functionally extinct – meaning that they no longer had any reproductive viability left – by scientists. Despite various conservation efforts during the 1990s, there were no confirmed sightings after 2002 until an expedition in 2006 failed to find any evidence of its existence. As such, the International Union for Conservation of Nature officially declared the Baiji extinct in December 2006.
Conclusion
The Baiji, also known as the Chinese river dolphin, was once a common species of freshwater dolphin found in China’s Yangtze River. Unfortunately, due to human activity such as overfishing and pollution, the species is now considered to be functionally extinct. The last confirmed sighting of a Baiji was in 2002, and many experts believe they have been extinct sine then. This is a great example of how human activities can lead to the extinction of an entire species, and serves as a reminder of how much care we must take with our environment.
