Kineski slatkovodni delfini iz reke Jangce se sada smatraju izumrlom vrstom, pošto najnovija opsežna ekspedicija nije uspela da pronađe ni jednog jedinog živog predstavnika.
Ovo je prvo izumiranje jedne krupne životinjske vrste u skorijoj istoriji.
Postoji još mala nada da se poneki pripadnik vrste krije negde u drugim vodenim tokovima na istoku Kine, ali nada je slaba. Naučnici procenjuju da čak i da se nađe par jedinki koje bi se razmnožavale u zatočeništvu, genetska baza ne bi bila dovoljna za opstanak vrste.
Poslednji put ove životinje su potvrđeno viđene 1997.
Citat:The rare Chinese river dolphin has gone extinct, according to scientists who could not find a single one of the animals during a six-week search on China's Yangtze River.
"It's possible that we missed one or two animals [during the search], but we can say the baiji is functionally extinct," August Pfluger, a Swiss economist-turned-naturalist who financed the expedition, said in a telephone interview from Wuhan, China.
(See China map)
"If there are any baiji left in the river, they won't have any chance of survival."
If Pfluger's team is correct, the baiji will be the first large aquatic mammal to have gone extinct since hunting and overfishing killed off the Caribbean monk seal in the 1950s.
Yangtze Dams, Ship Traffic to Blame?
