🐬 Did you know? The Baiji dolphin, now declared extinct, had a stomach divided into three parts – a feature not found in any other dolphin species. A poignant reminder of the unique life we lose with each extinction. BaijiDolphin UniqueNature 🌏
The Yangtze River dolphin, also known as the baiji dolphin , was a white, fresh-water dolphin native to the Yangtze River and Qiantang River in China as recently as the 1990s.
Today, it has not been seen in the Qiantang River since the 1950s. And while scientists spotted at least 400 individuals between 1979 and 1981 in the Yangtze River, a survey in the late 1990s found only 13 animals.The world’s only captive Yangtze river dolphin — So experts have had to declare the baiji white dolphin “functionally extinct” — meaning that even if some individuals still existed somewhere out there, the population is no longer viable.When the team of survey conservationists left the Chinese docks in 2006, they had two ships, each packed with a team of visual observers and acoustic equipment to listen for the whistles of the dolphins.
On the policy side, a lot of time typically passes between the point when researchers suggest a species has completely died off and when policymakers declare that species extinct.Most people are familiar with Shakespeare’s Romeo and Juliet story. Taylor says the tragic ending makes an apt illustration for the challenge of declaring a species extinct.
This creates a dilemma for conservation scientists who want to accurately describe what is happening to biodiversity.
