The Syr Darya sturgeon (Pseudoscaphirhynchus fedtschenkoi) is a species of fish in the Acipenseridae family. It is found in Kazakhstan, Tajikistan and Uzbekistan, where it is endemic to the Syr Darya River and, before its drainage, the Aral Sea. Due to the loss of its breeding site and damming projects over the length of the river, it is currently considered Critically Endangered and likely extinct, as no sightings have been reported since 1960.[1] The sturgeon is among the 25 “most wanted lost” species that are the focus of Global Wildlife Conservation’s “Search for Lost Species” initiative.[4]
