The Chinese paddlefish, one of the largest freshwater fish has been declared extinct in a study published in the journal Science of the Total Environment.
About:
The Chinese paddlefish (Psephurus gladius) was an iconic species, measuring up to 7 m in length, dating back from 200 million years ago, and therefore swimming the rivers when dinosaurs ruled the Earth.
Its ancestral home was the Yangtze River.
Recently, Chinese researchers declared it extinct based on the Red List criteria of the International Union for Conservation of Nature (IUCN).
Between 1981 and 2003, there were just around 210 sightings of the fish. The researchers estimate that it became functionally extinct by 1993, and extinct sometime between 2005-2010.
